M 6.0 IN SOUTHERN PERU PROBABLY PROMOTED BY GEOMAGNETIC/SOLAR FLARE EFFECTS
EARTHQUAKE SUMMARY FOR MAY 30, 2020
The strongest earthquake in the world today occurred as an M 5.9-6.1 in Southern Peru. NEIC reported it was felt with maximum intensity V in Puno, Peru at Lampa, Torata, Yunguyo, and IV in Juliaca, Puno, Moquegua, and Mollendo and II-III in Camana, Cusco, and Arequipa. GUC reported this earthquake was felt with intensity IV in Chile at Arica and Parinacota at Arica and Cuya; III in Pocon, Chile; in Tarapaca with IV in Alto Hospicio, Huara, Iquique, V in La Tirana, Pisagua and Ujina and III in Camina, Mamina, Pica, and in Quillagua, Antofagasta with III, Chile. This epicenter is located on the geomagnetic equator. A series of moderate solar flares occurred yesterday and today including the largest of the year and first M-class flare of the year (M1.1 at 07:24 UT) and several C-class flares. These increased the disturbance in the geomagnetic field to storm levels. The combination of this disturbance and SFE (Solar Flare Effects) probably triggered the M 6.0 on the geomagnetic equator in Peru today which occurred at the peak of the disturbance within minutes local solar midnight, a time when geomagnetic effects are most prominent. Enhanced seismicity on or near the geomagnetic equator is likely to continue for several days as noted in this summary:
"The geomagnetic field saw disturbed conditions today. The AP level was 14. High latitude geomagnetic field also saw disturbed conditions with AP at 17. This is the strongest disturbance in the geomagnetic field since AP reached 18 on April 20. Strong seismic enhancement is expected near the geomagnetic equator over the next several days." (May 30-31, 2020)
The M 5.9-6.1 was preceded by a foreshock of M 4.0 earlier in the day to the west of the mainshock epicenter. The last earthquakes of M>=5.9 within about 200 km of today's epicenter occurred as an M 7.0 on March 1, 2019 and an M 6.3 on December 1, 2016. Forecasts 124410 and 124416 had expected today's activity was likely around May 20 in this area.

The second largest earthquake of the day was an M 5.5 in the Talaud Islands of Indonesia. Like the event in Peru, it occurred on the geomagnetic equator and was probably enhanced by the geomagnetic storm which peak was simultaneous with the quake. It was not reported felt. This is the strongest earthquake in the Talaud Islands since an M 6.0 on February 6, 2020 and prior to that an M 5.5 on December 5, 2019. Forecast 124235 expected today's event was likely around May 31 to the west of today's epicenter.

The largest earthquake in the U.S. or Canada today was an M 4.3 in the aftershock area near Mammoth Lakes, California. NEIC reported this quake was felt with intensity II-III in California at Lee Vining, June Lake, Mammoth Lakes, Yosemite National Park, Coleville, Bishop, El Portal and Mariposa and in Nevada at Yerington and Hawthorne. This is the strongest event in this swarm north of Mammoth Lakes, California since an M 4.6 on May 15, 2020 at the start of this swarm. The strongest quakes in the swarm to date have been M 4.3-4.4. A stronger shock hit the area with M 5.2 on April 11, 220, the largest in the region since December 28, 2016 when an M 5.5-5.6 occurred. Today's activity occurred at the peak of the geomagnetic storm and may have been promoted by SFE. Forecasts 124301 and 124303 had expected this activity was likely around May 27-30.

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.

SEISMIC SWARM IN NORTHERN MID-ATLANTIC
EARTHQUAKE SUMMARY FOR MAY 29, 2020
The strongest seismicity in the world today occurred in the Northern Mid-Atlantic Ridge. These events of M 5.6, 5.4, 5.1 and 4.6 were not reported felt in this remote mid-ocean ridge. This is the strongest activity within about 200 km of this epicenter since a similar M 5.6 14 years ago on August 9, 2007. Forecast 124291 had expected today's activity at the end of May. This activity is at 103 degrees from the M 7.6 in the Kurils of March 25, 2020, the last major earthquake in the world. It was probably promoted by concentrated energy from that source. Puerto Rico, another area of high seismicity in recent months is at a similar distance from the Kuril Islands.

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 KERMADEC ISLANDS, NEW ZEALAND
EARTHQUAKE SUMMARY FOR MAY 28, 2020
A moderately strong earthquake of M 5.8 in the Northern Kermadec Islands of New Zealand today completed the set of such events in the area which followed landfall of TC Amphan last week. It also followed an M 5.9 to the north in the Tonga Islands, yesterday. This summary had expected this activity as:
"TC Amphan (01B) continued today in the area south of Pakistan with winds up to 105 kts as a major cyclone. This is the strongest cyclone ever recorded in this area of the Bay of Bengal. It is expected to track to the north possibly affect seismicity in Bangladesh, eastern Pakistan and central and southeastern Asia in the next week. The antipode of the expected landfall is a about 21S 92W in the South Pacific - a non-seismic region. Areas at 144 degrees from the expected landfall include Mexico and Guatemala, those near 103 degrees include areas off Washington State and the Kermadec Islands. These may see seismic enhancement with landfall of this powerful storm." (May 18-20, 2020)
and reviewed the progress to date in the previous issue of this summary as:
"A series of moderate earthquakes continued today in the Southwestern Pacific.
These included an M 5.9 in Tonga, an M 6.1 in Vanuatu and several moderate aftershocks; events in Fiji (M 4.3, 4.5) and in north and South Island, New Zealand of M 4.0 and 4.5. This activity is located at 101-104 degrees from the landfall of TC Amphan in Bangladesh late last week." (May 28-29, 2020)
Today's M 5.8 in the northern Kermadec Islands is the strongest event within about 200 km of this epicenter in the Kermadec Islands since an M 6.3 on March 14, 2020 and an M 5.8 on January 10, 2019. Prior to that the area had been quiet at this magnitude level for more than 30 years. It was not felt in this remote area. Forecast 124432 expected this event in this area was likely around May 29. This epicenter is at 103.0 degrees from the Amphan landfall location and was probably promoted by energy from that event.

P: 29MAY2020 124432 27.0S 177.0W 4.0-5.7 AABAA Tonga Islands
The Kermadec quake followed an M 5.9 in Tonga. The last earthquake in the region of Tonga within about 200 km of this epicenter with M>=5.9 was recorded nearly a year ago on June 2 and June 15, 2019 with M 5.9 and 6.1. Forecast 124430 had expected today's activity was likely around May 30 in this area. This epicenter in Tonga is at 104 degrees from the landfall of TC Amphan of May 22 and was probably enhanced by energy from that event.

Triggering of seismicity by stresses from TC Amphan was not limited to the Tonga-Kermadec-New Zealand arc today. Two moderate earthquakes also occurred in the immediate area where landfall occurred in Bangladesh and northeastern India with M 4.5 and 4.8. In particular an M 4.5 in Bangladesh at the landfall site of Amphan probably was a product of delayed triggering from stresses associated with Amphan. It is the strongest quake in the landfall area since an M 5.3 on September 12, 2018. Forecast 124292 had expected this activity was likely at the end of May.

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.

SEISMIC ACTIVATION CONTINUES IN SOUTHWESTERN PACIFIC
EARTHQUAKE SUMMARY FOR MAY 27, 2020
A series of moderate earthquakes continued today in the Southwestern Pacific.
These included an M 5.9 in Tonga, an M 6.1 in Vanuatu and several moderate aftershocks; events in Fiji (M 4.3, 4.5) and in north and South Island, New Zealand of M 4.0 and 4.5. This activity is located at 101-104 degrees from the landfall of TC Amphan in Bangladesh late last week. More such activity is expected in the area in the next several days before the effects of Amphan have dissipated. The strongest earthquake in the world today was an M 5.9 in Tonga north of the Kermadec Islands. NEIC reported it was felt with intensity II-III in Tonga at Tofoa-Koloua and Nuku'alofa. This continues seismic enhancement in the region of New Zealand, the Vanuatu Islands and Tonga which apparently was triggered by energy associated with landfall of TC Amphan in Bangladesh late last week. This summary had expected this as:
"TC Amphan (01B) continued today in the area south of Pakistan with winds up to 105 kts as a major cyclone. This is the strongest cyclone ever recorded in this area of the Bay of Bengal. It is expected to track to the north possibly affect seismicity in Bangladesh, eastern Pakistan and central and southeastern Asia in the next week. The antipode of the expected landfall is a about 21S 92W in the South Pacific - a non-seismic region. Areas at 144 degrees from the expected landfall include Mexico and Guatemala, those near 103 degrees include areas off Washington State and the Kermadec Islands. These may see seismic enhancement with landfall of this powerful storm." (May 18-20, 2020)
The last earthquake in the region of Tonga within about 200 km of this epicenter with M>=5.9 was recorded nearly a year ago on June 2 and June 15, 2019 with M 5.9 and 6.1. Forecast 124430 had expected today's activity was likely around May 30 in this area. This epicenter in Tonga is at 104 degrees from the landfall of TC Amphan of May 22 and was probably enhanced by energy from that event.

An M 5.1 in the Kermadec Islands area of New Zealand is the strongest within about 200 km of that event in the Kermadec Islands since an M 6.0 a month ago on April 14, 2020 and appears to be an aftershock of that mainshock. It was not reported felt in this remote area. Forecast 124443 had expected today's activity in this area was likely around May 28. This epicenter is located at 103 degrees from the landfall of TC Amphan and may have been promoted by energy from that event.

Strong aftershocks also continued today in the Vanuatu region. In the previous issue of this summary it had been noted when an M 6.1 hit the area on May 27:
"The strongest earthquake in the world today was an M 6.1 in Vanuatu. NEIC reported it was felt with intensity IV in Vila Shefa, Vanuatu. The mainshock was preceded by several foreshocks, including an M 4.8, 4.9 and 5.6 which were also lightly felt at Vila Shefa, Vanuatu. This is an area where strong volcanism has occurred over the past several years and these may be part of a volcanic eruption in the area. The last earthquake of M>=6.6 in the region within about 200 km of today's epicenter was an M 6.6 on July 31, 2019 at 179 km depth. The last such events at a shallow focus was an M 6.5 on August 21, 2018 and an M 6.1 on June 21, 2018. Forecast 124419 had expected today's activity was likely within about 25 km around May 24. These epicenters are at 103 degrees from the M 5.6 in Chiapas, Mexico two days ago and may have been enhanced by energy from that source." (May 26-27, 2020)

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.

QUAKES SHAKE VANUATU
EARTHQUAKE SUMMARY FOR MAY 26, 2020
The strongest earthquake in the world today was an M 6.1 in Vanuatu. NEIC reported it was felt with intensity IV in Vila Shefa, Vanuatu. The mainshock was preceded by several foreshocks, including an M 4.8, 4.9 and 5.6 which were also lightly felt at Vila Shefa, Vanuatu. This is an area where strong volcanism has occurred over the past several years and these may be part of a volcanic eruption in the area. The last earthquake of M>=6.6 in the region within about 200 km of today's epicenter was an M 6.6 on July 31, 2019 at 179 km depth. The last such events at a shallow focus was an M 6.5 on August 21, 2018 and an M 6.1 on June 21, 2018. Forecast 124419 had expected today's activity was likely within about 25 km around May 24. These epicenters are at 103 degrees from the M 5.6 in Chiapas, Mexico two days ago and may have been enhanced by energy from that source. Moderate seismicity in Crete, Greece was also at this distance from Chiapas today. A series of light earthquakes was also reported today in the Canary Islands in the Atlantic Ocean. These area located at 103 degrees from the last major earthquake in the world - the M 7.6 in the Kurils of March 25. The area of the Canary Islands is also subject to volcanism.

An unusual M 5.2 earthquake occurred today in the Southern East Pacific Rise.
Three earthquakes of M>=5.2 have hit within about 250 km of this epicenter in the past six years - an M 5.5 on January 23, 2016; an M 5.4 on May 4, 2019 and an M 5.8 on December 25, 2019. Today's event was not reported felt in this remote epicentral area. Forecast 124426 had expected today's event was likely within about 100 km of this epicenter around May 27. This event is near 105 degrees from the Banda Sea and could have been influenced by energy from that source.

An M 3.6-3.7 was widely felt in the Bakersfield area of Central California today. This is not part of any current aftershock sequence and may represent an area of stress where a larger quake may follow. NEIC reported it was felt with intensity II-III in Bakersfield, Lamont region. This is the strongest earthquake in the Bakersfield, California area within about 100 km since an M 3.8 on April 16, 2018. Forecast 124306 had expected today's event was likely within about 50 km around May 27.

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.

MANIPUR, INDIA SHAKES TO MODERATE QUAKE
EARTHQUAKE SUMMARY FOR MAY 25, 2020
The most widely felt earthquake in the world today occurred in Manipur, India with M 5.1. This event is near the landfall of TC Amphan several days ago and may have been triggered by that event. NEIC reported it was felt with maximum intensity V in Manipur, India and II-III in Moirang, Mayang, Imphas, Thoubal, in Assam at Silchar, Lala, Aizael and Kolasib, Mizoram. This is the largest earthquake within about 200 km of this epicenter since an M 5.9 on April 16, 2020 and prior to that an M 5.3 on April 4, 2019. Forecast 124292 had expected regional seismicity enhancement with TC Amphan was likely in the area around May 24.

The strongest earthquake in the world today was an M 5.4 in the area south of Guam. NEIC reported it was felt with intensity III in Mangilao, Guam. The last earthquake of M>=5.4 within about 200 km of Guam was an M 5.6 and an aftershock of M 5.5 on July 16 and 21, 2019. The last of significantly larger magnitude occurred as an M 5.8 on September 23, 2018. Regional seismicity often peaks during typhoon season, so this may be the opening event of several this summer in the region. Forecast 124051 had expected today's activity was likely in mid-May.

Aftershocks continued in the Cook Strait of New Zealand today following the M 5.5-5.9 quake yesterday. The largest of today's regional events was an M 5.0-5.6. NEIC reported it was felt with intensity V in Levin Manawatu-Wanganui and IV in Te Horo, Kapiti, and Porirua, Wellington. Lesser shaking was reported from Palmerston North, Wanganui, Lower Hutt, New Plyouth and Tapawera. GEONET reported this earthquake was felt with moderate intensity in Cook Strait and northern South Island. 20626 people reported feeling this event; 5854 with weak intensity; 10177 with light shaking; 3966 moderate; 582 strong; 22 with severe and 25 with extreme shaking. Forecast 124446 had expected this activity was likely within about 50 km of this epicenter around May 25. This summary noted the mainshock in the previous issue as:
"The last event in the Cook Strait within about 200 km of today's epicenter was an M 6.2 on January 20, 2014. There have been no larger quakes in the Cook Strait in the past 30 years. Forecasts 124222 and 124446 had expected today's activity was likely around May 19-25. This epicenter is at 103 degrees from the landfall of Amphan and 100-105 from events of M 6.5 in Idaho and Nevada and at the seventh node (52 degrees) from the Banda Sea and was probably promoted by energy from all these sources." (May 24-25, 2020)

The strongest earthquake in the U.S. or Canada today was an M 3.7 near Rock Mountain House, Alberta, Canada. It was not reported felt in this remote area.
The last earthquake in this area with M>=3.7 was an M 4.3 on March 10, 2019 and prior to that an M 4.3 on August 9, 2014 and of M 4.0 on June 10, 1997. Forecast
124377 had expected this activity in Alberta was likely around May 24 within about 25 km of the epicenter. This epicenter is at 103 degrees from the landfall of TC Amphan, similar to that of the events in Cook Strait, New Zealand and may have been promoted by energy from that source.

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.
