TONGA/FIJI REGION ACTIVE

 

EARTHQUAKE SUMMARY FOR OCTOBER 16, 2017

 

The strongest earthquakes in the world today occurred in the region of Tonga and Fiji. These events of M 5.5 and 5.3 and 5.1 were lightly felt in the area and may have been felt at Pangai, Ha'apai, Tonga according to data from NEIC. These areas became active as the geomagnetic storm ended today. They are located about 10 degrees south of the geomagnetic equator and may have been promoted by effects related to the geomagnetic storm. One of these, an M 4.9, occurred minutes of local solar noon and was probably promoted by tidal stresses which are high at this hour. An M 6.1 hit the Tonga area on October 8 about 500 km north of today's epicenter. The last of M>=5.5 within about 200 km of today's epicenter occurred on September 26, 2017 with M 6.5 and prior to that on June 27, 2017 with M 5.5  These earthquakes are located at 102 degrees from the Bouvet Island earthquake of M 6.7 on October 10. Seismic energy is concentrated on the surface at this  distance from large earthquakes and can help promote additional seismicity at this distance. Forecast 111188 had expected today's activity in mid-October.

An M 4.1 earthquake in South-Central Canada near Chesterfield today was teh strongest event located in Canada. This epicenter is north of Minnesota and light earthquakes in the area are not uncommon. Three earthquakes of M>=4.1 have hit the area in the past 25 years - an M 4.2 on March 10, 2012; an M 4.4 on May 8, 2004 and an M 5.4 on December 6, 1997. Forecast 111155 had expected a moderate earthquake in this area within about 200 km of this epicenter was possible around October 10. This epicenter is located at 142 degrees from the Bouvet Island earthquake of October 10 and may have been promoted from that source. Other areas at this distance from Bouvet today included an M 4.0 in Hawaii and light earthquakes in Northern California.

The strongest earthquake today in the U.S. or Canada was an M 4.5 in the Bering Sea of Alaska. This is in the epicentral region of the Bouvet Island (M 6.7) quake of October 10 and may have been promoted by energy from that source. The only previous earthquake of moderate magnitude this year was an M 4.3  on June 29, 2017. The last earthquake in the Bering Sea within about 250 km of this epicenter with M>=4.5 was an M 4.5 on March 11, 2012. The last of larger magnitude was an M 4.9 on July 10, 2006. Moderate earthquakes in the area often come in pairs, so another such event may occur in the next several days.

An earthquake of M 4.0 also occurred in the Lana'i City area of the Hawaiian Islands. This event occurred in the western portion of the state and is the strongest west of 157 West longitude since an M 4.1 on July 8, 2003. Earthquakes in the past two years of M 4.2 and M 4.7 occurred about 150 km northeast of today's epicenter on July 30 and February 17, 2017. This epicenter is located at 144 degrees from the Bouvet Island M 6.7 of October 10, 2017. Forecast 111255 had expected this event was possible around October 12.

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.

EARTHQUAKE SUMMARY FOR OCTOBER 15, 2017

 

Global seismicity remained at quiet levels today as the current major geomagnetic storm persisted. There were no earthquakes of M>=5. The largest occurred near the coast of Valparaiso, Chile where it was felt. NEIC reported this earthquake of M 4.9 in Central Chile was felt with intensity IV in La Ligua, Valparaiso and Illapel, Coquimbo and II-III in the area(s) of Valparaiso, Vina del Mar, Quilpue, Quillota, Villa Alemana, Calera, Cabildo and San Antonio, Chile. Forecast 111445 had expected this event around October 17.

"The geomagnetic field was at minor storm conditions today.  The AP level was 26. High latitude geomagnetic field saw major storm conditions with AP at 49. The geomagnetic storm today is the strongest since September 28 when AP reached 55. This could promote a strong earthquake today but more likely 4-5 days after the geomagnetic storm ends.  These are most likely near the geomagnetic equator and/or at high latitudes." (October 14-15, 2017)

 

The most widely felt earthquake in the U.S. or Canada today occurred as an M 3.7 in Arkansas. NEIC reported it was felt with maximum intensity IV in Arkansas at Dell, Manila, Etowah, Leachville, Keiser, Osceola, Blytheville, Monette, with lesser shaking of II-III in Arkansas at Caraway, Luxora, Lepanto, Wilson, Senath. It was also felt lightly in Missouri at Arbyrd, Cardwell, Steele, and in general within about 50-100 km of the epicenter. Felt reports also were noted from Tennessee, Mississippi, Illinois, Kentucky, Indiana, Louisiana, and Minnesota.  This is the strongest earthquake in Arkansas during 2017. The last earthquake within about 200 km of this epicenter with M>=3.7 occurred on April 4, 2015 with M 4.0 and prior to that on June 4, 2014 (M 3.8). Forecast 111046 had expected a light to moderate earthquake in this area around October 9.

The strongest earthquake in the U.S. or Canada today was an M 4.1 in the Pribilof Islands, Alaska. The only event in this region during the past year was an M 4.5 at this same epicenter of June 14, 2017. This is a remote area and these events were not reported felt. Forecast 111384 had expected regional seismicity around October 12.

An unusual earthquake also occurred today as an M 3.4 in the area west of Vernonia in western Oregon.  NEIC reported this earthquake of M 3.4  in Oregon was felt with maximum intensity IV in Oregon at Seaside, Gales Creek, and II-III in the area(s) of Vernonia, Astoria, Nehalem, North Plains, Rockaway Beach, Portland and Halsey, Oregon.  The last earthquake within about 100 km of this epicenter with M>=3.4 occurred as an M 3.6 on November 16, 2016. The only other such event in the past 25 years in this region was an M 3.7 ten years ago on September 24, 2007. This, as well as quakes in northern California, Hawaii, Idaho and central California lie at 143-148 degrees from the Bouvet quake of October 10, a distance where concentrated seismic energy returns to the surface and may help promote further seismicity. A reader (PB) sent the following first-hand account of this earthquake:

 

“Last night there was a quake listed by USGS as WNW of Vernonia, OR. It was actually centered in Jewell, a small rural area in the Northwest Oregon Coast Range. I live about 5-7 miles from the epicenter and even though it was only a 3.4 it woke me from a sound sleep and shook my house like crazy. Pictures on the walls tilted and a few small items fell over. I had gone to bed early and made sure I did all I could to ensure a good night's sleep (massage chair, chamomile tea, warm room etc) since I was supposed to be up very early for work. Because I was sleeping so deeply I don't know how long it was shaking before it woke me. Of course I coulnd't go back to sleep, heart pounding so hard it was scary. So did some research online for area quakes and found one reference to local faults on our county website.” (PB October 15, 2017)

An unusual earthquake of M 3.5 occurred in northwestern France today. EMSC reported this earthquake was felt lightly in France at Bouffere and Saint-Clementin. This may be related to stresses from Hurricane Ophelia which remnants passed to the west of this epicenter today. This activity had been expected in the previous issue of this summary as:

 

 

"Hurricane Ophelia continued in the North Atlantic with winds up to 115 kts. It is expected to continue as a hurricane and to track west into the Azores and Europe over the next several days. Seismicity in France, Spain and Portugal will probably increase as Ophelia approaches that region." (October 15, 2017)

 

Forecast 111372 had expected this event to the southeast of this epicenter around October 12. The last earthquake in the area within about 100 km of this epicenter with M>=3.5 was an M 2.9 on January 4, 2017.

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.
