LIGHT QUAKE RESUMES SEISMIC SERIES IN SOUTH CAROLINA

EARTHQUAKE SUMMARY FOR MARCH 9, 2024

A M 2.8 earthquake was lightly felt in South Carolina today. NEIC reported this earthquake of M 2.8 in South Carolina was felt with intensity up to IV in the area(s) of South Carolina in Elgin. This continues a series in the area which continued throughout much of the year 2023. It is the strongest earthquake in this area in more than a year - since an M 2.9 on February 18, 2023. This series began in December, 2021 with an M 3.6. At the time this summary noted in this regard:

"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.

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)

Forecast 161123 had expected today's event in South Carolina was likely within about 50 km around March 9, 2024.

The strongest earthquake in the world today was an M 5.4 in the area of Fiji. The last earthquake of equal or larger magnitude in Fiji was an M 5.8 on March 2, 2024. Today's earthquake occurred within minutes of local solar midnight and was probably promoted by strong tidal stresses which maximize near this hour and which are associated with the new moon of March 10 as noted in this and previous summaries:

"The new moon will arrive at 09:00 on March 10, 2024. Longitudes at local solar noon are near 45 East while those at local solar midnight are near 135 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Greece and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (March 5-9, 2024)

The M 5.8 on March 2 occurred within minutes of local solar noon as noted

at the time in this summary:

"An earthquake of M 5.8 also occurred in the region of Fiji today. It was not reported felt in this area. This event occurred near local solar noon and may have been promoted by strong tidal stresses which maximize near this hour and perhaps by stresses associated with the full moon" (March 2, 2024)

Forecast 161221 had expected today's event within about 100 km was likely around March 8, 2024.

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 COSTA RICA

EARTHQUAKE SUMMARY FOR MARCH 7, 2024

The strongest earthquake in the world today was an M 5.7 in Costa Rica. NEIC reported it was felt with intensity up to IV in Costa Rica at Tamarindo. EMSC reported a booming noise and strong jolts in Costa Rica at Cabo Velas and Tierras Morenas. A similar M 5.7 occurred on June 10, 2021 about 150 km southeast of today's epicenter near Costa Rica, the only event with equal or greater magnitude in the area in the past four years. That event was closely associated with a solar eclipse also on June 10, 2021.

"The strongest earthquake in the world today was an M 5.7 in Costa Rica. NEIC reported it was felt in Costa Rica with maximum intensity VI at Chacanita, Puntarenas,V in Esparta and IV in Jaco and Atenas. Lesser shaking occurred in Samara, AGuanacasts, Papuera, Santa Cruz, Miramar, Juntas, and Santiago, Alajuela. The last earthquake of equal or larger magnitude in Costa Rica was an M 6.0 on August 24, 2020." (June 10, 2021)

Forecasts 160987 and 161043 had expected enhanced seismicity in Costa Rica and Nicaragua was likely around March 7, 2024.

An earthquake of M 5.2 with aftershock of M 5.0 also rattled Southern Qinghai, China today. This is the strongest earthquake in Southern Qinghai, China since an M 5.5-5.9 on August 14, 2022. At the time this summary noted:

"A moderately strong earthquake was also recorded in southern Qinghai, China today with M 5.5. It was not initially reported felt but was likely damaging

in the epicentral area. Reports from this area of China are often delayed by several days, so check later for damage reports. The epicenter is in a lightly populated plateau and there were no local reports of damage from this earthquake. This is the strongest earthquake within about 200 km of this epicenter since an M 5.7 on March 19, 2021 and an M 5.9 on October 17, 2016. No events of M>5.9 have been recorded in the area in the past 30 years." (August 14, 2022)

Forecast 161132 had expected enhanced seismicity within about 100 km of

today's epicenter was likely around March 9, 2024.

An unusual earthquake of M 3.4 occurred today in eastern Quebec, Canada. It was followed by aftershocks of M 2.7 and 2.7 but was not reported felt. The only earthquake of M>=3.4 within about 200 km of this epicenter in Eastern Quebec in the past four years was an M 3.5 on January 29, 2024.

Forecast 161138 had expected enhanced seismicity in this region was likely around March 4, 2024. This epicenter is located at the third node (120 degrees) from the M 7.6 in Mindanao, Philippines of December 2, 2023 and may have been promoted by energy from that source.

MODERATE SWARM IN VANCOUVER, B.C. CANADA

EARTHQUAKE SUMMARY FOR MARCH 6, 2024

The strongest earthquake felt in the U.S. or Canada today was an M 4.5-4.6 in the Vancouver area of British Columbia, Canada. NEIC reported light intensity was felt in Tofino, Canada. This event was accompanied by a moderate swarm of events of M 3.0-4.0. The mainshock occurred within minutes of local solar midnight - a time when tidal and geomagnetic stresses maximize - and was probably promoted by such stresses.

The last earthquake with M>-4.6 within about 100 km of today's epicenter occurred on April 13, 2023 (M 6.0) and August 8, 2022 (M 4.6). At the

time of the April, 2023 event this summary noted:

"The strongest earthquake in the world today was an M 6.0 off the western coast of Vancouver Island, British Columbia, Canada. NEIC reporte intensity I-III in British Columbia at Port Hardy, Port MacNeill, Nanaimo, Sidney, Vancouver, White Rock and in Washington State at Friday Harbor, Eastsound, Ferndale and Port Townsend among others. The last earthquake in the Vancouver Island area within about 150 km of this epicenter with M>=6 was an M 6.3 on December 25, 2019 and an M 6.0 on December 23, 2019 But the last earthquake within about 100 km of this epicenter with M>=6 was an M 6.5 on October 22, 2018." (April 13, 2023)

Forecast 161171 had expected today's event in this region was likely around March 8. This activity is at the third node (120 degrees) from the

M 6.7 in Macquarie Island area of March 3 and may have been promoted by energy from that that source. A series of light earthquakes in Western Texas and in southern Texas shared this distance to Macquarie today.

The strongest earthquake in the U.S. or Canada today however was an M 4.8 in the Unimak Island region of Alaska.

This event was not reported felt in this remote epicentral area. The last earthquake of M>=4.8 in the Unimak Island area was an M 4.9 on September 12, 2023 and prior to that an M 5.0 on August 14, 2023. At the time this summary noted:

"The strongest earthquake in the U.S. or Canada today was an M 5.0 in Unimak Island, Aleutians, Alaska. NEIC reported and aftershock of M 4.2 in Unimak Island, Alaska was felt with intensity II-III in the area(s) of Unimak Island, Alaska in Akutan. This activity occurred within minutes of local solar noon and was probably promoted by high tidal stresses with the upcoming new moon. This is the strongest earthquake in the Unimak area since an M 5.1 on September 9 and January 11, 2021. No events of significantly larger magnitude have hit this area in the past 3.5

years." (August 14, 2023)

Forecast 161191 had expected today's event was likely within the Unimak Island area within about 50 km of today's epicenter around March 7.

The most active area of the world today was the area of northern Mindanao, Philippines where a swarm of earthquakes including two of M 5.1 occurred. NEIC reported this earthquake of M 5.1 in Mindanao, Philippines was felt with intensity up to III in the area(s) of Mindanao, Philippines in Kinablangan.

EMSC reported light shaking in Davao City, Mindanao. PHIVOLCS reported intensity III in Surigao del Sur in Lingig; II in City of Bislig; in Davao Oriental at Baganga, Caraga and Manay; and in Davao de Oro in Maragusan Mabunturan, Montevista, Monkayo and Pantukan. These are aftershocks of an M 7.6 of December 2, 2023. At the time this summary noted:

"The M 7.6 in Mindanao today is the strongest in the Philippines in the region of Mindanao within about 300 km of today's epicenter since an M 7.6 on August 31, 2012, the only such event in this area in at least 35 years. Other events of M >=7.5 hit somewhat further

to the south of today's epicenter on July 23, 2010, March 5, 2002 and January 1, 2001 (all with M 7.5)." (December 2, 2023)

Forecast 160991 had expected today's seismic enhancement in Mindanao was likely around March 7. These epicenters are at the fifth node (72 degrees)

from the M 6.7 in Macquarie of March 3, 2024 and may have been promoted by energy associated with that event.

STRONG MACQUARIE IS. AFTERSHOCK

EARTHQUAKE SUMMARY FOR MARCH 5, 2024

The strongest earthquake in the world today was an M 5.9-6.1 in the Macquarie Island area. It was not reported felt in this remote area. This is an aftershock of an M 6.7 that hit the area on March 4 and an M 5.5 of February 28, 2024. Further aftershocks of this type may be expected in the next several weeks. Forecast 161249 had expected today's event was likely within about 100 km in the Macquarie Islands around March 4. When the M 6.7 hit this summary noted in this regard:

"Forecast 161249 had expected today's event within about 100 km was likely in the Macquarie Island area around March 4, 2024. It is near the antipode of the energetic volcanic eruption in southern Iceland and may have been promoted by energy from that source. It is also at 102 degrees from the events of M 6.7 in Brazil of late January 2024 and may have been promoted by energy from that source." (March 4, 2024)

An earthquake of M 4.8 south of Iceland in the Reykjanes Ridge also occurred today. This activity is part of the current volcanism in the area of the North Atlantic and Iceland. The M 6.7 and 5.9-6.1 in the Macquarie Islands today is likely to further enhanced seismicity at this antipodal area.

Forecast 161186 had expected today's event in the north Mid-Atlantic was likely

within about 50 km around March 4, 2024.

Two unusual earthquake occurred today in eastern U.S. The larger of these was an M 2.8 in Illinois but an M 2.7 also occurred in northern Texas. NEIC reported this earthquake of M 2.5 in Illinois was felt with intensity up to III in the area(s) of Illinois in Pinckneyville. The last earthquake in Illinois within about 100 km of today's epicenter was an M 3.1 on December 18, 2023. At the time this summary noted:

"An unusually large M 3.1 earthquake shook areas of Illinois (US) today. NEIC reported it was felt with intensity up to IV in Waltonville, Illinois.

NEIC also reported light shaking in Wayne County, Illinois near Mount Vernon. EMSC reported moderate shaking in Du Quoin, Illinois. An earthquake of M 3.6 hit about 300 km north of this epicenter on November 15, 2023 but the last event of M>=3.1 in Illinois within about 150 km of this epicenter occurred on September 19, 2017 and September 9, 2017 with M 3.8 and 3.1. Avid readers of this summary may recognize these dates as the time of the last major X-flare as described in this summary on December 14-15, 2023. At the time of the M 3.1 on September 9, 2017, this summary noted:

"An unusual M 3.2 earthquake today shook areas of Illinois, Indiana and Wisconsin. NEIC reported it was felt with intensity II-III in Illinois at Mount Carmel, Bone Gap, Browns, West Salem, Albion, Owensville, Allendale, Ellery, Grayville, Saint Francisville, Lawrenceville, Greenup, Marion, Nokomis; in Lake Geneva, Wisconsin and in Indiana at Evansville, Vicennes, Princeton, Owensville.

This epicenter is within kms of the point of maximum solar eclipse of the

August 21, 2017. The last earthquake in Illinois within about 100 km of this epicenter was an M 3.4 on May 30, 2015 and prior to that similar quakes on November 20, 2012 and June 5, 2008. A moderate quake of M 5.4 hit today's epicenter on April 18, 2008 and today's event may be an aftershock of that. Forecast 110474 had expected this earthquake in mid-September. The M 8.2 in Mexico hours earlier may have helped promote this event in Illinois. " (September 9, 2017, December 18, 2023)

Forecast 161092 had expected today's event within about 50 km was likely

around March 2.

The last earthquake of M>=2.7 within about 100 km of today's epicenter in

northern Texas was an M 3.7 on December 9, 2013 about 100 km southeast of today's epicenter. No other earthquakes in this region of northern Texas west of 98 West longitude have occurred in the past 35 years with M>=2.7. At the time of the event in December, 2013, this summary noted:

"Another light to moderate earthquake was widely felt in northern Texas today. This event of M 3.7 is the strongest within 100 km of this epicenter in at least 25 years and represents a migration of the regional seismicity to the west. The current swarm which has been blamed on fracking and well injection technology began on June 24, 2012 about 100 km southeast of today's epicenter with M 3.5 and has gradually migrated to the north and west over the past 1.5 years with the latest an M 3.6 near Fort Worth about 50 km east of today's epicenter which occurred near Mineral Wells, Texas." (December 9, 2013)

Forecast 161124 had expected regional seismic enhancement in this area was

likely around March 6.

MODERATE QUAKES SHAKE TURKEY

EARTHQUAKE SUMMARY FOR MARCH 4, 2024

Two moderate earthquakes occurred in Turkey today. This is consistent with the expectation of this area becoming active with the new moon of March 10 as noted in this and previous issues of this summary:

These two earthquakes occurred near local solar noon and midnight and were likely promoted by tidal stresses which maximize near this hour.

EMSC reported the earthquake of M 4.4 in Central Turkey was felt with intensity up to III in the area(s) of Central Turkey in Yesilyurt, Kizilcoaba, Helete, Niyazi, Fevzi Pasa, Cakmak, 19 Mayis, and as far as Syria. Forecast 161127 had expected this earthquake in central Turkey was likely around March 3.

The M 4.8 in Western Turkey was widely felt in the general region of Istanbul, Turkey where a major earthquake is considered likely in the near future.

NEIC reported this earthquake of M 4.3-4.8 in Western Turkey was felt with intensity up to IV in the area(s) of Western Turkey in Hamdibey. The last earthquake within about 100 km of today's epicenter in western Turkey with M>=4.7 occurred on December 4, 2023. At the time this summary noted:

"A moderate earthquake of M 5.1 was widely felt in the area of Istanbul, Turkey today. NEIC reported intensity up to VI in Mudanya, Turkey. EMSC reported moderate to strong shaking with this earthquake was felt in Turkey at Mudanya, Nilufer, Gorukle, Osmangazi, Demirtas, Gemlik, Kurtul, Mahmudiye, Cali, Bursa, and as far as Edremit, Burhaniye, Bolme, Gomer more than 200 km from the epicenter. A foreshock of M 3.1 occurred five minutes before the mainshock. EMSC reported it was felt with light intensity in Turkey at Mudanya, Nilufer, Gorukle, Icmeler among others. A series of light aftershocks followed the mainshock and were felt lightly in the epicentral area. This earthquake occurred near local solar noon and may have been promoted by tidal stresses which maximize near this hour. The last earthquake within about 200 km of today's epicenter with M>=5.1 was an M 5.7 on September 26, 2019." (December 4, 2023)

Forecast 161129 had expected this event was likely within about 50 km around

March 4, 2024. This epicenter is at 144 degrees from the Macquarie Island M 6.7 of March 3, 2024 and at 102 degrees from the M 6.7 in Brazil of January 20, 2024 and was probably promoted by energy from those sources.

ALASKA REGION CONTINUES ACTIVE

STRONG QUAKE IN MACQUARIE AREA HITS WITH STRONG GEOMAGNETIC STORM

EARTHQUAKE SUMMARY FOR MARCH 3, 2024

The geomagnetic field saw minor storm conditions today. The AP level was 29. High latitudes saw minor storm conditions with AP 49. Middle latitudes were at active conditions with AP 20.

On March 1, 2024 this summary noted in anticipation of this:

"Active conditions in the geomagnetic field could lead to enhanced seismicity at high auroral latitudes and near the geomagnetic equator. Recent seismicity in these regions in the Macquarie Island area south of New Zealand of M 5.5 on February 28; in Sumatra and Indonesia may help provide clues as to where such geomagnetic induced seismicity is likely with a strong geomagnetic storm at this time. This is most likely around March 3-4, 2024 according to SWPC." (March 1, 2024).

The AP reading of 29 today is the most disturbed the ionosphere has been since December 18, 2023 when it reached AP 36. The storm began as a sudden commencement event at about 16:15 UT according to data from SWPC reaching KP 7. At the time of the sudden commencement of this storm a strong earthquake of M 6.7 occurred in the Macquarie Island region south of New Zealand. It appears very likely that this event was triggered by the onset of this geomagnetic storm. Today's event in the Macquarie Island area is the strongest in the world since an M 7.0 in Southern Xinjiang, China of January 22, 2024 (nearly 6 weeks). Two other events of M>=6.7 have hit in the world during the year 2024 - an M 7.6 in western Honshu, Japan on January 1, 2024 and an M 6.7 in the Talaud Islands of January 8, 2024.

This earthquake of M 6.7 is the strongest located within about 300 km of this epicenter in the Macquarie Island region in the past 35 years at least. A foreshock in the Macquarie Island area of M 5.4 occurred on February 28, 2024.

At the time this summary noted:

"The strongest earthquake in the world today was an M 5.4 in the Macquarie Islands south of New Zealand. This event was not reported felt in this remote area. The last earthquake in the Macquarie Islands within about 500 km of this epicenter with M>=5.4 was an M 6.0 on June 9, 2023. At the time this summary noted:

"The M 6.0 in the Macquarie Island area was the strongest within about 250 km of that epicenter since an M 6.0 on April 12, 2007. The only event in this region in the past 35 years of significantly larger magnitude was an M 6.3-6.5 on November 5, 1994. Moderate earthquakes in the Macquarie Island area more recently occurred on June 8 (M 4.8) and as an M 5.3 on June 5, 2023." (June 9, 2023)

It is likely that today's event in Macquarie was promoted by strong tidal stresses with the full moon of February 24 as it occurred near the longitude of maximum stress with that event as noted in this and previous issues of this summary:

"The full moon arrived on February 24 at 12:30 UT. Longitudes which are near local solar noon at this time are located near 8 West longitude and those at local solar midnight at 172 East longitude. In the west these include areas of western Europe and the mid-Atlantic Rift as far as Iceland to the South Sandwich Islands and the southern Mid-Atlantic and in the east areas near local solar midnight at the time of this full moon include the Vanuatu-Tonga-Fiji-Kermadec Islands and New Zealand and in the north the western Aleutians. These are the most like regions to experience strong tidal triggering within about a week of this full moon. They include a number of areas near the IDL which could see a strong to major earthquake at this time." (February 21-27, 2024)

Further enhancement of seismicity in these regions is still expected in the next several days. In particular this includes region of the western Aleutians in the Rat and Andreanof Islands in the north and in the New Zealand/Tonga arc in the south. This region has shown several unusual and moderate earthquakes in the past several days including an M 5.1 in Methven, South Island, New Zealand yesterday as noted in the previous issue of this summary:

"A moderate earthquake of M 4.6-5.1 was felt today in central South Island New Zealand. NEIC reported intensity up to III near Methven, New Zealand. EMSC reported light to moderate shaking in Christchurch, New Zealand. ... The last earthquake within about 150 km of this epicenter with M>=5.1 occurred on September 19, 2023 with M 5.6 and prior to that as aftershocks in November 2016 of an M 7.8 about 150 km northeast of this of November 13, 2016. At the time of the September, 2023 event this summary noted:

"The strongest earthquake in the world today was an M 5.6-6.2 in central South Island, New Zealand. NEIC reported it was felt with maximum intensity V in Canterbury at Rolleston and IV in Oamaru, Timaru, Lincoln, Christchurch with lesser shaking of II-III in Ashburton, Lyttelton, Te Puru-Thornton Bay, Waikato and Denedin Otago. GEONET reported it at M 6.2 and that it was felt with light intensity in the area of Central South Island, New Zealand. Of 14338 felt reports 4779 reports of light and 6786 of weak intensity with 1749 of moderate shaking and 169 with strong 2 with severe and 11 with extreme intensity came from the area. The last earthquake within about 150 km of this epicenter with M>=5.6 occurred on February 14, 2016 with M 5.8. The last of M>=6.2 was the Christchurch earthquake of M 7.0 of September 3, 2010 about 100 km north of today's epicenter." (September 19, 2023)

Today's event was probably promoted by high tidal stresses with the full moon of February 24 as it occurred at the longitude of maximum stress with that alignment" (February 27, 2024)

Today's epicenter is near 100 degrees from the M 7.6 in western Japan of January

1. 2024 and may have been promoted by energy from that source." (February 28, 2024)

Forecast 161249 had expected today's event within about 100 km was likely in the Macquarie Island area around March 4, 2024. It is near the antipode of the energetic volcanic eruption in southern Iceland and may have been promoted by energy from that source. It is also at 102 degrees from the events of M 6.7 in Brazil of late January 2024 and may have been promoted by energy from that source..

An earthquake of M 5.5 also occurred south of Sumatra today. This is located near the geomagnetic equator and was probably promoted by geomagnetic stresses with the day's geomagnetic storm. BMG reported this earthquake of M 5.6 in Bengkulu, Indonesia was felt with intensity up to III in the area(s) of Bengkulu, Indonesia in Bengkulu at Enggano and II in Ogan Komering, Ulu, Muara Enim, Lahat, Lawang, Alam, Kaur, Seluma and Kepahiang among others. The antipode of this epicenter in Sumatra is in northern Colombia, a region which has been active in recent days with a series of moderate events in late February starting February 20, 2024. Additional seismic enhancement is likely in this area in coming days. The last earthquake within about 200 km of this epicenter in southern Sumatra with M>=5.5 occurred as an M 6.2 on April 15, 2023. At the time this summary noted:

"NEIC reported the earthquake South of Sumatra of M 5.5-6.2 was felt with maximum intensity VII in Pagar Alam, Sumatra; IV in Lampung at Kota Bumi, Pringsewu and Bandar and in Jakarta with light intensity.
