STRONG EARTHQUAKE SHAKES ARGENTINA, BOLIVIA AND CHILE AFTER X-CLASS SOLAR FLARE

 

EARTHQUAKE SUMMARY FOR MAY 10, 2022

 

The strongest earthquake in the world today was an M 6.8 in Jujuy, Argentina. This is the largest earthquake in the world since an M 7.0 in the Loyalty Islands 1.5 months ago on March 31, 2022. It occurred at an intermediate depth and was felt with moderate intensity over a large area. NEIC reported maximum intensity V in Salta, Argentina and IV in Jujuy, Argentina and in Chile in Tarapaca, Antofagasta, Atacama, with lesser shaking in Bolivia. This epicenter is near the antipode of the M 6.3 in Taiwan which occurred on May 8 and may have been promoted by strong antipodal focusing from that source. The solar eclipse of April 30 was visible in this area and this summary had anticipated a strong earthquake was possible in this area of South America following that alignment as:

 

"The new moon arrived on April 30, 2022 at 20:28 UT. Longitudes which were at local solar noon at the time of this new moon are near 125 West while those at local solar midnight are near 55 East. In the west these include areas of western U.S. and Canada and the East Pacific Rise and in the east areas of Iran, the Caspian Sea to Turkey. These are the areas most likely to see tidal triggering during the next week but tidal triggering is possible in other areas as well and would most likely include seismicity near local solar midnight or noon. This is a partial solar eclipse visible in the Southeast Pacific and Southern South America and is most complete in Chile and Argentina where a strong earthquake may occur in conjunction with this eclipse. It is the first solar eclipse since December 21, 2021." (April 28-May 2, 2022)

 

Today's activity may also have been promoted by Solar Flare Effects (SFE) from

an X-class flare that occurred several hours earlier. SWPC parameters for this flare which occurred near local solar noon in Argentina follow:

 

Flare #    START  MAX       END    CLASS     DATE    Flux (Jm-2)

 

4790       1350   1355      1359   X1.5      (May 10, 2022)   3.1E-02  

 

Today's M 6.8 in Argentina is the strongest earthquake within about 200 km  of this epicenter since an M 7.2 near this epicenter on May 12, 2000, 22  years ago. An M 7.0 also occurred about 100 km north of this on May 24, 1993.  Forecast 143381 had expected today's event within about 100 km in Argentina was likely to occur around May 6.

Other moderately large earthquake occurred today as well. An M 5.4 in the South Sandwich Islands may also have been promoted by SFE from the flare 4790. It was preceded by an M 4.8 foreshock. Forecast 143412 had expected today's activity in the South Sandwich Islands was likely around May 8.

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.

RONG QUAKE IN BISMARCK SEA, PAPUA NEW GUINEA

 

EARTHQUAKE SUMMARY FOR MAY  9, 2022

 

The strongest earthquake in the world today was an M 6.3 in the Bismarck Sea, Papua New Guinea. NEIC reported it was felt with intensity VII in Madang, Papua and II in Lorengau Manus, Papua New Guinea. This continues enhanced regional seismicity in this area which has included an M 6.0 on April 28, 2022. At the time this summary noted in this regard:

 

"The strongest earthquake in the world today was an M 6.0 in Papua New Guinea. It was not reported felt in this area. This epicenter is located near the geomagnetic equator and may have been promoted by the geomagnetic storm currently in progress as noted in this and previous summaries:

 

"The geomagnetic field saw disturbed conditions today. The AP level was 14. High latitudes also saw active conditions with AP 21. This is sufficient to activate higher levels of seismicity at high latitudes and near the geomagnetic equator in the next several days." (April 28, 2022) 

 

The last earthquake with M>=6 within eastern New Guinea and within about 200 km of today's epicenter was an M  6.0 on July 21, 2021 and an M 6.1 on April 27, 2021, one year ago." (April 29, 2022)

 

The last event of M>=6.3 within about 200 km of this epicenter in the Bismarck Sea was an M 6.3 on February 7, 2021 and an M 6.3 on January 26, 2018.  Forecast 143169 had expected today's event within this are was likely about 150 km to the south was likely in early May.

An M 4.1-4.5 earthquake shook areas of central France today. NEIC reported it was felt with intensity VI in Montlucon, Auvergne, France. This is a very unusual epicenter, the largest within about 100 km of this epicenter in at least 30 years. Recent earthquakes within about 200 km of this epicenter occurred as an M 4.8 about 250 km southeast of this on November 11, 2019 and an M 4.1 about 150 km northeast on December 3, 2016. An event of M 4.0 hit about 150 km to the west of this on July 26, 2010. Forecast 143287 had expected  enhanced seismicity in France south of today's epicenter was likely around May 8.

An M 5.2 also shook regions of Central Honshu, Japan today. NEIC reported intensity II-III in Kanagawa, Tokyo, Saitama Prefectures, Japan. This is the strongest earthquake in Central Honshu within about 150 km of this epicenter since an M 5.2 on January 15, 2021. These events are at an intermediate depth (300-400 km ) and are only slightly felt on the surface. The last event of larger magnitude in this area was an M 6.3 on July 27, 2019. Forecast 143254 had expected today's event in this region was likely around May 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.

STRONG EARTHQUAKE SHAKES TAIWAN

 

EARTHQUAKE SUMMARY FOR MAY  9, 2022

 

The strongest earthquake in the world today was an M 6.1-6.4 in Taiwan. NEIC reported it was felt with intensity IV in Taipei, III in Taoyuan and Hsinchu Counties, Taiwan. CWB reported this earthquake was felt with intensity III in Yilan, Hualien, Taipei, Taitung, II in Nantou, Taichung, Taoyuan, Hsinchu, Miaoli, Yunlin, Changhua, Chiayi, Kaohsiung, Tainan, Pingtung, I in Keelung, Penghu, Lienchiang, and Kinmen Counties, Taiwan. This may be an aftershock of the M 6.7 in Taiwan of March 22 and the M 6.2 near this epicenter on January 3, 2022. Forecasts 143224 and 143223 had expected this activity in Taiwan was likely around May 6-8.

A series of earthquakes also occurred in the Jan Mayen Islands region north of Iceland today. The strongest of these was an M 5.4. These appear to be aftershocks  of an M 5.7 which hit the area on February 14, 2022. At the time this summary noted in this regard.

 

"The strongest earthquake in the world today was an M 5.7 in the Jan Mayen Island area north of Scandinavia. It was not reported felt in this remote area. Aftershocks of M 4.3 and 4.7 followed within two hours of the mainshock. This is the strongest earthquake within about 200 km of this epicenter in the Jan Mayen area since an M 6.7 about 200 km northeast of this epicenter on November 9, 2018 and an M 6.8 in the same area on August 20, 2012." (February 14, 2022)

 

Forecast 143362 had expected today's activity within about 50 km was likely around May 6. Much of this activity occurred near local solar midnight and may have been promoted by high tidal stresses.

A moderately strong M 4.9-5.5 shook the U.S. Virgin Islands today. NEIC reported it was felt with intensity IV in the U.S. Virgin Islands at Saint John and Saint Thomas and in Tortola, British Virgin Islands. Intensity III was also felt in Culebra, Vieques, Fajard, Celca, Puerto Rico and in the U. S. Virgin Islands at Christiansted, Frederiksted. The last earthquake in the Virgin Islands within about 150 km of this epicenter with equal or greater magnitude was an M 6.1 on October 11, 2008.

 

"The Virgin Islands is also a region which often shows strong triggering due to geomagnetic effect and this earthquake was likely triggered by the geomagnetic storm. The timing of the maximum effects of this geomagnetic storm is such as to coincide with the period of greatest danger of large earthquakes ...

 

The earthquake in the Virgin Islands of M 6.1 today was reported by NEIC to have been felt with maximum intensity V in Puerto Rico at Naranjito, ... It was the most widely reported earthquake (by NEIC) in the region of Puerto Rico in at least the last 10 years and the second most widely felt in the area in that time period after an M 7.3 on November 29, 2007 that occurred south of this in Dominica." October 12, 2008).

 

Forecast 143195 had expected today's earthquake was likely in this area around May 8 in this area.

A light earthquake of M 3.3-3.5 was widely felt in the southeastern U.S. today. This event in South Carolina of M 3.3 was reported by NEIC to have been felt with intensity IV in South Carolina at Lugoff, Elgin, Columbia, Camden, Rembert, Blythewood, III in Ridgeway, and with light shaking from Canada to Florida with intensity II-IV in North Carolina, Georgia, Tennessee, Alabama, Kentucky, Virginia, DC. Ohio, Florida, Maryland, Delaware, Pennsylvania, Mississippi, Indiana, Michigan, Connecticut, Massachusetts, Missouri, Vermont, Iowa, Quebec and Oklahoma. This is the strongest earthquake in South Carolina within about 150 km of this epicenter since an M 4.1 about 100 km southwest of this on February 15, 2013 and an M 3.9 on April 13, 1998. Forecast 143273 had expected today's event within about 50 km was likely around May 5. This continues recent enhanced seismicity in this region of South Carolina which began on December 28, 2021 as reported in this summary at the time:

 

"A series of earthquakes also occurred today in South Carolina. The largest of these was an M 3.3-3.6 (EMSC). NEIC reported the mainshock at M 3.3 was felt with intensity IV in South Carolina with intensity IV in Lugoff and Elgin and III in Columbia, Camden, Rembert, Ridgeway, Blythewood. An aftershock of M 2.5 was felt in South Carolina at Lugoff, Elgin, Columbia, Camden, Ridgeway, Blythewood, and other areas of South Carolina. In the previous issue of this summary it was noted that seismicity in the  area of South Carolina often associated with strong quakes in the area of Greece which moderately large quakes shook yesterday as:

 

"An M 5.4 in the Dodecanese Islands of Southern Greece was reported felt with

intensity III in Karpathos, Dodecanese Islands, Greece by NEIC. News reports indicate there were no major damages or injuries with this earthquake. An M 5.1 foreshock was reported felt with intensity II-III in Urla, Izmir, Turkey. Earthquakes in this area of Greece are occasionally followed by increases in seismicity in the southeastern U.S. A great earthquake in Greece in late August 1886, for example was followed immediately by light earthquakes in Charleston, South Carolina and an M 7.7 there on August 31, 1886 as noted  in the August 31, 2021 issue of this summary" (December 26-27, 2021)

 

Likewise when the only event of M>=3.3 of the past 7 years in South Carolina

occurred on September 27, 2021 this summary noted the coincidence of this event with major activity in southern Greece as:

 

"A light earthquake of M 3.3 was widely felt in South Carolina today. NEIC reported maximum intensity VI in South Carolina at Summerville, Lasson and North Charleston with II-III shaking in Charleston, Goose Creek, Johns Island, Saint George, Walterboro, Sumter, Tybee. It was also reported lightly felt in Georgia, North Carolina, Virginia and Florida among others. A foreshock of M 2.8 was felt with intensity II-III in South Carolina at Summerville, Ladson, North Charleston, Ridgeville, Charleston, Goose Creek, Moncks Corner.

 

...

 

The M 7.7 in Charleston, South Carolina of August 31, 1886 followed a great  earthquake in southern Greece several days earlier and has been suggested on several occasions in this and other reports (even at the time of that quake) to have been a far-field aftershock of the M 8.4 in Greece as noted in the history section of this summary:

 

"The Charleston, South Carolina earthquake. This earthquake was preceded by four days of small foreshocks which began immediately after an M 8.4 in central Greece. That earthquake may have disturbed the groundwater sufficiently to lubricate the fault responsible for the for the Charleston quakes ultimately triggering the strong event." (August 31, 2021)

 

 

The M 3.3 today is the strongest earthquake within about 150 km of this epicenter since an M 3.6 on December 16, 2008." (September 27-28, 2021)

 

The only earthquake of M>3.6 in South Carolina in the past 10 years was an M 4.1 on February 15, 2014 and prior to that an M 4.4 on November 11, 2002 and August 21, 1992 also with M 4.4." (December 28, 2021)

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.

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.

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 WEST OF PORTUGAL

 

EARTHQUAKE SUMMARY FOR MAY  6, 2022

 

An unusual earthquake of M 4.6 occurred west of Portugal today on the Azores-Cape St. Vincent Ridge. It was not reported felt in this remote area. This is the strongest earthquake within about 200 km of this epicenter since an M 4.6 on January 22, 2008. More recent earthquakes slightly further from today's epicenter occurred on February 17, 2020 and November 1, 2018 with M 4.6-4.7.  The area saw some great earthquakes about 50 years ago, and may be the source of the great Lisbon earthquake of November 1, 1755. Forecast 143250 had expected enhanced seismicity in this region was likely around May 4.

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.

MODERATELY STRONG QUAKE IN MINDANAO, PHILIPPINES

 

EARTHQUAKE SUMMARY FOR MAY  4, 2022

 

The strongest earthquake in the world today was an M 5.6 in Mindanao, Philippines. NEIC reported it was felt with intensity II-III in Southern Mindanao at Mambago, Davao, Tapia, Buayan, Koronadal and Barra. This is the largest earthquake in Mindanao within about 200 km of this epicenter since an M 6.0 on April 20, 2022. These appear to be aftershocks of an M 7.1 that shook the area on August 11, 2021.  Forecasts 143157 and 143156 had expected enhanced seismicity in this area was likely around May 5-9.

A series of moderate earthquakes also occurred in the region of Valparaiso, Chile today. These included events of M 5.1 and M 5.2. The solar eclipse of April 30, 2022 was visible in this area and tidal stresses associated with this alignment may have helped promote this activity as noted in this and previous issues:

 

"The new moon arrived on April 30, 2022 at 20:28 UT. Longitudes which were at local solar noon at the time of this new moon are near 125 West while those at local solar midnight are near 55 East. In the west these include areas of western U.S. and Canada and the East Pacific Rise and in the east areas of Iran, the Caspian Sea to Turkey. These are the areas most likely to see tidal triggering during the next week but tidal triggering is possible in other areas as well and would most likely include seismicity near local solar midnight or noon. This is a partial solar eclipse visible in the Southeast Pacific and Southern South America and is most complete in Chile and Argentina where a strong earthquake may occur in conjunction with this eclipse. It is the first solar eclipse since December 21, 2021." (April 28-May 2, 2022)

 

Today's activity is associated with an M 5.0 in the region of May 3 which was noted in this summary at the time as:

 

 

"The strongest earthquake felt in the world today was an M 5.0 in the area of Valparaiso, Chile. This is the strongest earthquake near Valparaiso since an M 5.7 on November 3, 2021 and may be an aftershock of that earthquake to the southeast of today's epicenter. No other significantly larger earthquakes have hit the Valparaiso area in the past 1.5 years although quakes of M 5.0-5.1 hit on June 12 and July 31, 2021.   Forecast 143395 had expected this event was likely within about 100 km around May 6." (May 3, 2022)

 

NEIC reported the earthquake of M 5.1 in Valparaiso, Chile was felt with intensity II-III in the area(s) of Valparaiso, Chile in La Ligua, Vina del Mar and in Santiago.  This followed an M 5.2 off the coast of Valparaiso earlier in the day which was felt with intensity V in Valparaiso; VI in La Ligua and IV in Vina del Mar and III in O'Higgins and Santiago.

The strongest earthquake in the U.S. or Canada today was an M 4.2 off the coast of northern California. NEIC reported it may have been felt in northern California at Arcata. This is the largest earthquake within about 100 km of this epicenter off the coast of northern California since an M 4.3 on May 2, 2021 one year ago. The last of significantly larger magnitude in the region was an M 4.6 on January 27, 2021.  Forecasts 143308 had expected enhanced seismicity in this region around May 3-6.

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.
