MODERATE SEISMICITY EXPANDS IN CENTRAL AND NORTHERN CALIFORNIA

 

EARTHQUAKE SUMMARY FOR OCTOBER 15, 2019

 

The strongest earthquake in California today was an M 4.7 south of San Francisco. NEIC reported it was felt with maximum intensity VI in the epicentral area and V in Gonzales with IV in Hollister, Soledad and San Juan Bautista. Intensity II-III was also felt in Salinas, Paicines and other areas of central California. This is not a classical aftershock of yesterday's M 4.6 in San Francisco but is a separate mainshock. It was probably triggered by stress redistribution following yesterday's event. It occurred within minutes of local solar noon, a time when tidal stresses maximize and may have been promoted by stresses associated with the full moon as noted in previous issues of this summary:

 

 

"The full moon arrived on October 13 at 21:08 UT. Longitudes which were sub-solar at this time area near 45 East and 135 West longitude. These include areas of Turkey and Iran in the east and the northwestern edge of the North American Plate in the west. These are most likely to see tidal triggering at this time but tidal triggering can occur in a number of tectonic settings. Seismic enhancement is most likely a promoter of seismicity near local solar noon and local solar midnight." (October 11-14, 2019)

 

An earthquake of M 3.4 was also felt with intensity II-III in northern San Francisco Bay today according to NEIC. Felt reports came from Pleasant Hill, Concord, Walnut Creek, Lafayette and in general within about 50 km of the epicenter. This is north of the M 4.6 mainshock yesterday but could be part of the aftershock series. Forecast 119284 had expected this event within about 15 km was likely around October 18.

P: 18OCT2019 119284    38.0N  122.3W 2.5-4.3 AAAAA  Central California         

 

In the previous issue of this summary it was noted that this activity is near the culmination of a period of enhanced seismicity in central and northern California as:

 

 

"It is likely that moderate earthquakes in the area including to the south will continue for several more days. Several days ago this summary had warned of this type of activity in the San Francisco Bay area was likely in mid-October when an M 3.4 occurred in the area as:

 

"A light earthquake of M 3.4 was widely felt in the area of San Francisco Bay area of California today. NEIC reported this earthquake of M 3.3 in the San Francisco, California area  was felt with intensity II-III in the area(s) of the San Francisco, California area at San Jose, Milpitas, Livermore, Santa Clara, Fremont, Sunnyvale, Morgan Hill and in general within about 50 km of the epicenter. This continues regional seismicity which has been at enhanced levels during October. The area often sees elevated seismicity in mid-October, perhaps related to  meteorologic promoters. The Loma Prieta quake of M 7.2 on October 20, 1989 was probably triggered by strong solar flares of X10+ which occurred on the same day." (October 10-11, 2019)

 

Several days earlier a series of events in the San Francisco area was noted as follows in this summary:

 

"When a similar event of M 3.5 hit north of this on October 1, 2019 this summary noted:

 

"An unusual earthquake of M 3.5 hit off the coast of Northern California today but south of the normal seismicity in the region. Unusual earthquakes in this area can indicate a built-up stress in need of release in a larger earthquake. This is the farthest event to the west in the area 39-40N 139-142W in the past 30 years. It may be related to the energetic swarm currently occurring in the Hayward area of the San Francisco Bay region which also continued today." (October 1, 6, 15, 2019)

 

A strong nor-easter is occurring in New England at this time. It is thought it may reach atmospheric pressures never before encountered in October. Nor'easter's have been linked in this summary to enhanced seismicity in the northwestern portion of North America and this could extend the activation of central California to the north over the next several days.

 

The M 4.8 occurred in a creeping section of the San Andreas Fault zone where moderate or large earthquake are rare. The last earthquake of M>=4.8 within about 75 km of today's epicenter was an M 4.8 on August 27, 2011 and prior to that an M 4.8-4.9 on May 14, 2002. The last of significantly larger magnitude in the region was an M 5.2 on August 12, 1998. Forecast 119283 had expected a moderate earthquake was possible within about 25 km of today's epicenter around October 17.

 

A number of light aftershocks followed the M 4.8. An M 2.7 foreshock was also felt with intensity IV in Salinas and II-III in Soledad, San Juan Bautista, Watsonville, Santa Cruz and San Jose, California.

The strongest earthquake in the world today was an M 5.1 in northern Vanuatu. It was not reported felt in this area. The last earthquake within about 150 km of this epicenter with M>=5.1 was an M 6.0 on August 24, 2019. Forecast 119406 had expected this event within about 100 km was likely around October 16.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES SAN FRANCISCO BAY, CALIFORNIA

 

EARTHQUAKE SUMMARY FOR OCTOBER 14, 2019

 

A moderate M 4.5 earthquake in the San Francisco Bay, California region today was widely felt in the San Francisco area. Minor damage was reported. NEIC reported more than 68,000 people reported felt effects from this earthquake. It was felt with maximum intensity V in Pleasant Hill, Concord, Walnut Creek, and IV in Lafayette, and within about 150 km of the epicenter. A series of light to moderate foreshocks and aftershocks were also lightly felt.

 

It is likely that moderate earthquakes in the area including to the south will continue for several more days. Several days ago this summary had warned of this type of activity in the San Francisco Bay area was likely in mid-October when an M 3.4 occurred in the area as:

 

"A light earthquake of M 3.4 was widely felt in the area of San Francisco Bay area of California today. NEIC reported this earthquake of M 3.3 in the San Francisco, California area  was felt with intensity II-III in the area(s) of the San Francisco, California area at San Jose, Milpitas, Livermore, Santa Clara, Fremont, Sunnyvale, Morgan Hill and in general within about 50 km of the epicenter. This continues regional seismicity which has been at enhanced levels during October. The area often sees elevated seismicity in mid-October, perhaps related to  meteorologic promoters. The Loma Prieta quake of M 7.2 on October 20, 1989 was probably triggered by strong solar flares of X10+ which occurred on the same day." (October 10-11, 2019)

 

Several days earlier a series of events in the San Francisco area was noted as follows in this summary:

 

"When a similar event of M 3.5 hit north of this on October 1, 2019 this summary noted:

 

"An unusual earthquake of M 3.5 hit off the coast of Northern California today but south of the normal seismicity in the region. Unusual earthquakes in this area can indicate a built-up stress in need of release in a larger earthquake. This is the farthest event to the west in the area 39-40N 139-142W in the past 30 years. It may be related to the energetic swarm currently occurring in the Hayward area of the San Francisco Bay region which also continued today." (October 1, 6, 2019)

 

The activity in San Francisco began several hours before local solar midnight and was probably promoted by strong tidal stresses associated with the full moon as noted in this summary in the new moon seismic forecast in previous issues:

 

"The full moon arrived on October 13 at 21:08 UT. Longitudes which were sub-solar at this time area near 45 East and 135 West longitude. These include areas of Turkey and Iran in the east and the northwestern edge of the North American Plate in the west. These are most likely to see tidal triggering at this time but tidal triggering can occur in a number of tectonic settings. Seismic enhancement is most likely a promoter of seismicity near local solar noon and local solar midnight." (October 11-14, 2019)

 

The last event in the San Francisco Bay area within about 75 km of today's epicenter which exceeded M 4.5 occurred on August 24, 2014 when an M 6.0 hit the Napa area. The last within the San Francisco Bay area was an M 5.6 more than 11 years ago on October 31, 2007. Forecasts 119065 and 119284 had expected today's event in mid-October within about 10 km of the mainshock epicenter. The activity in the San Francisco Bay area is near 103-105 degrees from the Banda Sea and Seram in Indonesia and may have been promoted by recent strong earthquakes in that area. It may also be related to regional stress redistribution following the M 7.1 in Ridgecrest, California of July 6, 2019.

Minutes before the San Francisco Bay quake an M 2.6-3.2 was widely felt on the south shore of Lake Erie, Ohio. NEIC reported intensity II-III in Ohio at Madison, Thompson, Perry, Geneva, Painesville, Ashtabula, Willoughby, Eastlake, Conneaut and Cleveland. The relation between these two events is not well known, but this summary has previously noted that earthquakes in the Ohio-Pennsylvania area are often followed by significant seismicity in the area of California. Several P-phases from Ohio could have been present at the epicenter in California (including PcP) at the time of the subsequent quake 8.5 minutes later. A similar event of M 2.6 in Pennsylvania followed the San Francisco quake today.  The last earthquake of M>=2.6 within about 150 km of today's epicenters occurred as an M 4.0 on June 10, 2019 but the last within the southern event in this range was an M 3.4 on June 3, 2017. Forecast 119352 had expected today's activity within about 25 km was likely around October 21.

The strongest earthquake in the world today was an M 5.9-6.0 in Southern Sumatra, Indonesia. NEIC reported it was felt with intensity II in Bengkulu, Indonesia. This is the strongest earthquake in Southern Sumatra within about 200 km of this epicenter since an M 6.4 on August 13, 2017. Three earthquakes of M 5.9, 5.9 and 6.1 hit about 250 km northwest of today's epicenter on February 2, 2019, the only such events since 2017.  Forecast 119233 had expected today's event was likely within about 100 km of the epicenter around October 17.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKES IN SOUTHERN OCEANS

 

EARTHQUAKE SUMMARY FOR OCTOBER 13, 2019

 

The strongest earthquake in the world today were of M 5.2 in the Kermadec Islands, New Zealand and of M 5.1 in the Prince Edward Island region of the South Indian Ocean. Neither was reported felt in these remote areas.  The earthquake in the Prince Edward Islands region is the strongest in that area since an M 5.7 on October 23, 2015. Forecast 119204 had expected activity in the are in early October.

An M 6.0 occurred near the epicenter in the Kermadec Islands on September 27, 2019 and today's event is probably an aftershock of that. Forecast 119426 had expected today's event within about 100 km around October 14.

The strongest earthquake in the U.S. or Canada today was an M 4.2 in the Alaska Peninsula. The last earthquakes in the Alaska Peninsula within about 150 km of this epicenter with equal or greater magnitude occurred as a series in July, 2018 and included three events of M 4.5. Forecast 119367 had expected today's event to the west was likely around October 15.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE TOKYO, JAPAN QUAKE PROMOTED BY TYPHOON HAGIBIS

 

EARTHQUAKE SUMMARY FOR OCTOBER 12, 2019

 

The strongest earthquake felt in the world today was an M 5.3 in the region southeast of Tokyo, Japan. NEIC reported it was felt with intensity IV in Chiba and II-III in Kanagawa, and Tokyo, Japan. It was probably triggered by the passage of Typhoon Hagibis near this epicenter earlier in the day. Typhoon Hagibis was deadly in Japan with more than 30 killed and hundreds injured with much property damage as this storm passed through the Tokyo region. This summary had expected enhanced seismicity in eastern Honshu with the passage of Typhoon Hagibis in previous issues as:

 

"A Super-typhoon (Hagibis) is moving up southern Japan threatening the Izu Islands and then Tokyo in the coming several days. This has been a promoter of a number of moderate earthquakes in the region of Guam and the Mariana Islands already." (October 10, 2019)

 

and

 

"Super-Typhoon Hagibis continued today in the region of the Honshu, Japan with winds up to 80 kts. It killed several and produced massive flooding in southern Honshu with much damage today. It is expected to track to the  north. Seismicity is expected to be enhanced in southern  and eastern Japan in the next week." (October 10-12, 2019)

 

The last earthquake within about 100 km of today's epicenter which exceeded magnitude M 5.3 occurred more than a year ago on July 7, 2018 with M 5.9. Earthquakes of M 5.3 have hit the area most recently on June 24, 2019; May 17, 2018 and February 19, 2017. Forecast 119082 had expected today's event was likely around October 8 but this was changed (see above) by more recent updates to around October 13.

The strongest earthquake in the U.S. or Canada today was an M 3.8-4.1 off the coast of southeastern Alaska near Juneau, Alaska. NEIC reported this earthquake of M 3.8-4.1 in Southeastern Alaska was felt with intensity II-III in the area(s) of Elfin Cove, Alaska. The last earthquake within about 150 km of today's epicenter with M>=4.1 was an M 5.9 on September 10, 2019 with the last full moon. Today's event is probably the largest aftershock to date of that event.  Forecast 119152 had expected this activity within about 100 km was likely around October 5-11.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE EARTHQUAKE IN GULF OF ALASKA - STRONGEST IN MORE THAN A YEAR

 

EARTHQUAKE SUMMARY FOR OCTOBER 11, 2019

 

The strongest earthquake in the U.S. or Canada today was an M 5.0 in the Gulf of Alaska. It may have been felt lightly in Kodiak and Homer, Alaska. This earthquake is the strongest in the Gulf of Alaska aftershock zone in nearly 1.5 years - since an M 5.5 on May 8, 2018. These are both aftershocks of the M 7.9 in the Gulf of Alaska which occurred January 23, 2018.

An unusual earthquake of M 2.5 occurred today in British Columbia, Canada.  NEIC reported this earthquake of M 2.5 in British Columbia was felt with intensity II-III in the area(s) of British Columbia at Nelson. This is the strongest earthquake within about 100 km of this epicenter since a similar M 3.2 on November 22, 2017 the only other such event in the past five years.

A pair of events of M 4.5 in the Ionian Sea of Greece was widely felt today. NEIC reported maximum intensity V in Goumeron Ilia, Greece and IV in Kalamakion, Poros, Ketallina, Katastrion, Kalamakion, Lithakia, Pantokrator, and Planos, Zakinthos, with lesser shaking within about 100 km of the epicenter. NEIC reported these earthquakes of M 4.5 in the Ionian Sea were felt with intensity II-III in the area(s) of the Ionian Sea at Killini Ilia, Greece. The last earthquakes in the Ionian Sea within about 200 km of these epicenters with M>=4.5 occurred as an M 4.7 on September 19, 2019 after a series of M 4.5 events in the area in July through September, 2019. Forecast 119076 had expected today's activity was likely around October 9.

The strongest earthquakes in the world today were both of M 5.3 and occurred in the Southwest Pacific in New Britain and Tonga. Both regions are normally active at this magnitude level so this is probably not significant seismicity for the region. Neither event was reported felt. The earthquake in Tonga was the strongest within about 200 km of that epicenter since an M 5.4 on August 21, 2019. The earthquake in Tonga followed similar events within about 150 km of that epicenter which occurred on September 20 (M 5.4, 5.3) and an M 5.7 on August 5, 2019. Forecasts 119006 and 119178 had expected this activity in early October.

MODERATE EARTHQUAKES SOUTHEAST OF ISTANBUL, TURKEY

 

EARTHQUAKE SUMMARY FOR OCTOBER 10, 2019

 

A series of moderate earthquakes, including an M 4.0-4.2, occurred today southeast of Istanbul, Turkey. It is not a classical aftershock of the activity southwest of Istanbul which occurred September 24-26 with maximum M 5.7 on September 29. The two epicenters (today's and that of late September) may define weak spots in the Anatolian fault in the region across which a strong earthquake could occur shortly. The last event within about 100 km of today's epicenter was an M 4.2 on June 25, 2016. Forecast 119128 had expected the area would be active in early October.

 

NEIC reported these earthquakes of M 4.2 in Turkey were felt with intensity II-III in the area(s) of Turkey at Yalova and Istanbul.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

SUPER-TYPHOON HAGIBIS EYES JAPAN

 

EARTHQUAKE SUMMARY FOR OCTOBER 9, 2019

 

Two earthquakes were felt today in the region of Tokyo, Japan. These events of

M 4.6 and 3.3 are not large by Japanese standards but are occurring within the confines of this great metropolitan complex and could be seen as important precursory phenomena. The Tokai earthquake is long overdue. A Super-typhoon (Hagibis) is moving up southern Japan threatening the Izu Islands and then Tokyo in the coming several days. This has been a promoter of a number of moderate earthquakes in the region of Guam and the Mariana Islands already. One of the most deadly earthquakes in Tokyo occurred shortly after a typhoon hit the city on September 1, 1923. This summary had described the effects of that earthquake as:

 

"The great Tokyo earthquake. This event caused up to $3 billion (U.S. Dollars) damage. More than 142,000 were killed. A tsunami was generated. This earthquake is usually referred to as the Kwanto earthquake. Up to 38,000 residents of Tokyo were burned to death in an open area where they had congregated following the earthquake for safety. The firestorm which followed th quake destroyed libraries, museums, at collections, archives and scientific data among other irreplacable structures and items. The earthquake was located in Sagami Bay southwest of Tokyo. At least 15 lines of vertical faults were found with displacement up to 6 feet. Leveling showed uplifts up to 2 meters along the Sagami Bay. The tsunami reached up to 10 meters. Many groundwater effects were observed including pulsating earthquake fountains.  More than 128,000 houses were destroyed in the quake and up to 450,000 were burned in the ensuing fire. A hotel built one year earlier with great ability to move (architect: Frank Lloyd Wright) survived with only a few cracks and was used as hospital and first aid station following the earthquake.  Building techniques in Tokyo contributed to the firestorm. These included building close to the ground and paper thin walls." (September 1, 2019)

 

Although rebuilt with strict building codes, current estimates of deaths in a similar Tokyo earthquake approach 10-100 thousand killed.

 

The last earthquake of significantly larger magnitude than M 4.5 in the Tokyo area was an M 5.0 on July 24, 2019. Earthquakes of M 4.5-4.6 hit the area on Septebmer 14 and July 28, 2019. Forecasts 119081 and 119082 had expected today's activity was likely in the Tokyo area around October 9.

The strongest earthquake in the world today was an M 5.4 in the Macquarie Island region south of Australia and New Zealand. This event was not reported felt in the region. It is the second event of M 5.4-5.5 in Macquarie in the past 10 days. The last event within about 200 km of this epicenter with M>=5.4 occurred on October 1, 2019 with M 5.5. The last of larger magnitude in the region was an M 5.7 on June 16, 2013.

A similar event of M 5.5 occurred north of New Zealand today in the area east of North Island. It was not reported felt by GEONET. This and the Macquarie Island

M 5.4 occurred at opposite ends of the seismic zone through New Zealand and may be related. The last earthquake of M>=5.5 within about 200 km of today's epicenter was an M 6.2 on May 18, 2018 and prior to that an M 5.6 on July 7, 2015.  Forecast 119198 had expected activity in this region was likely around October 6.

A light earthquake of M 3.4 was widely felt in the area of San Francisco Bay area of California today. NEIC reported this earthquake of M 3.3 in the San Francisco, California area  was felt with intensity II-III in the area(s) of the San Francisco, California area at San Jose, Milpitas, Livermore, Santa Clara, Fremont, Sunnyvale, Morgan Hill and in general within about 50 km of the epicenter. This continues regional seismicity which has been at enhanced levels during October. The area often sees elevated seismicity in mid-October, perhaps related to  meteorologic promoters. The Loma Prieta quake of M 7.2 on October 20, 1989 was probably triggered by strong solar flares of X10+ which occurred on the same day. Today's event is the strongest since an M 3.5 on October 5, 2019 and prior to that an M 4.3 on July 16, 2019. Forecast 11905 had expected today's event was likely around October 11.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES HAWAII

 

EARTHQUAKE SUMMARY FOR OCTOBER 8, 2019

 

The strongest earthquake in the U.S. or Canada today was an M 4.0 in Hawaii. NEIC reported it was felt with intensity II-III in Hawaii at Naalehu, Paoa, Volcano, Mountain View, Captain Cook, Hilo, Honomu, Kailua  Kona, Laupahoehoe and Kamuela. This event is located near the Loi'hi Seamount south of the island of Hawaii. It may represent a resurgence of seismicity in this area.

It is only the second event of M>=4 south of Hawaii in the past year  an M 4.2 hit the same epicenter on August 22, 2019. Forecast 119028 had expected today's activity was likely around October 7.

An unusual M 3.8 also occurred in northern Canada in Devon Island, Nunavut today. It was not reported felt in this remote area. An M 6.0 hit this epicenter on January 8, 2017 and was followed by aftershocks for about a month. Today's event is probably an aftershock of the 2017 event. No events of M>=3.8 have been recorded within about 300 km of today's epicenter since early, 2017.

The strongest earthquake in the world today was an M 5.5 in the Pacific-Antarctic region of the South Pacific. It is part of a series of ocean ridge events which have been described in the previous issue of this summary.  The last earthquake within about 300 km of this event with M>=5.5 was an M 5.9 on May 1, 2018 and prior to that an M 5.7 on July 28, 2017.

An unusually large M 4.6 occurred offshore Turkmenistan in the Caspian Sea today. NEIC reported this earthquake of M 4.6 in he Caspian Sea was felt with intensity II-III in the area(s) of the Caspian Sea at Corat Sumqayit, Azerbaijan. The last earthquake within about 200 km of this epicenter of significantly larger magnitude was an M 4.9 on January 7, 2018. Forecast 119114 had expected today's event was likely within about 100 km of today's epicenter around October 10.

Moderate seismicity also continued in the Guam and Mariana region today with an

M 4.6 north of Guam. As noted in previous issues of this report this was probably promoted by the passage of Super Typhoon Hagibis as:

 

"Typhoon Hagibis formed today in the region east of Guam with winds up to 125 kts. It is expected to track to the west and north reaching Honshu, Japan around October 12. Seismicity in Guam is expected to be enhanced in the next several days as this storm moves through the region." (October 5-6, 2019)

 

Forecast 119042 had expected today's event was likely around October 7.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE SEISMICITY ON HIGH-LATITUDE MID-OCEAN RIDGES

 

EARTHQUAKE SUMMARY FOR OCTOBER 7, 2019

 

A series of moderate earthquakes occurred today on the world's high-latitude mid-ocean ridges. These were not reported felt in these remote areas. The strongest of these occurred in the South Shetland Islands, Reykjanes Ridge, South of Australia and in the Prince Edward Islands of the south Indian Ocean. Some, but not all of this activity had been forecast in previous issues of this summary.

 

Forecast 119201 had expected the event south of Australia within about 100 km  of that epicenter. It was nearly antipodal to the M 4.6 in the Reykjanes Ridge in the north Atlantic. That event had been expected within about 150 km of the epicenter around October 5.

The largest earthquake reported felt in the world today was an M 4.7 in Bhutan, Asia. It is the strongest quake in Bhutan since an M 4.9 and 5.5 on July 19, 2019. It is probably a regional aftershock of the M 5.5.  NEIC reported this earthquake of M 4.7 in Bhutan  was felt with intensity II-III in the area(s) of Bhutan at Trashigang; in Gauhati, Assam, IKndia and Itanagar Arunachal Pradesh, India and in Myanmar at Myitkyina and Banmo, Kachin. Forecast 119051 had expected this event to the southeast was likely around October 11.

Seismicity also continued today in the Mariana Islands where an M 4.9 occurred in the Alamagen region today. This event was probably promoted by the passage of Super Typhoon Hagibis today. This had been expected in the previous issues of this summary as:

 

 

"Typhoon Hagibis formed today in the region east of Guam with winds up to 125 kts. It is expected to track to the west and north reaching Honshu, Japan around October 12. Seismicity in Guam is expected to be enhanced in the next several days as this storm moves through the region." (October 5-6, 2019)

 

Forecast 119036 expected this activity was likely around October 9.

The most unusual earthquake in the U.S. or Canada today occurred in northeastern Kentucky with M 2.4. It was not reported felt in this area. The last earthquake within  about 100 km of today's epicenter with M>=2.4 in eastern Kentuck occurred as an M 2.7 on January 21, 2018 and prior to that as an M 2.6 on  November 24, 2017. Forecast 119125 had expected activity in this region was likely around October 7.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.
