SEISMICITY TAKES A BREAK

 

EARTHQUAKE SUMMARY FOR MARCH 15, 2025

 

It was a relatively quiet day in global seismicity today. No significant earthquakes were reported. The strongest event was an M 5.0 in northern Chile. The current geomagnetic storm was declining, there were no solar flares of M- or higher class and tropical cyclones were limited to a dissipating cyclone south of Madagascar which was not expected to promote important seismicity at this time.

 

An unusual M 3.0 earthquake occurred today in southern Mississippi (US). NEIC reported it was felt in Mississippi with intensity III in Braxton, Magee, Pinola, and II in Raleigh, Taylorsville and Meridian. The last earthquake of M>=3.0 within about 200 km of this epicenter in Mississippi was recorded as an M 3.2 hit the area along with a series of similar events in March through June, 2015. It is not clear if these were mining related explosions.

 

A strong outburst of tornadoes hit Mississippi about the time of this earthquake and may have helped promote this event.

 

Forecast 170909 had expected enhanced seismicity in southeast U.S. was likely

in mid-March.

Today's projected seismicity map follows for the coming week.

 

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 OAXACA, MEXICO RELATED TO TC IVONE

 

EARTHQUAKE SUMMARY FOR MARCH 14, 2025

 

Moderately strong earthquakes occurred today in Oaxaca and Guerrero, western Mexico with M 5.6-5.9  and as an M 6.0 in the South Sandwich Islands.  NEIC reported the earthquake in Oaxaca with M 5.6 but local networks placed the magnitude up to M 5.9 (INET, BMKG, BGS). NEIC reported it was felt with intensity up to IV in Oaxaca, Mexico at Huajuapan, Juxtlahuaca, Oaxaca; III in Pochutla, Puerto Escondido, Santa Lucia del Camino; in Puebla at Momoxpan, Zinacatepec and in Cuernavaca, Morelos and in the Mexico City region at Zacamulpa. EMSC reported it was felt with moderate shaking in Oaxaca at Chalcatongo de Hidalgo, Oaxaca de Juarez, La Perla, Heroica Puebla de Zaragoza, Ciudad de Huitzuco, Mexico City, Cuernavaca, Ciudad Nezahualcoyotl, Venustiano Carranza, Miguel Hidalgo, Cuauhtemoc, Cuajimalpa de Morelos, and Tlalnepantla.

 

The last earthquake in Oaxaca or Guerrero, Mexico with M>=5.6 within about 200 km of today's epicenter occurred on March 20, 2021 with M 5.7. The last of larger or equal magnitude then M 5.9 was an M 5.9 on February 19, 2018. At the time this summary noted:

 

 

"A strong aftershock of M 5.9 shook the Oaxaca aftershock zone early on February 19. It was reported by NEIC to have had maximum intensity IV in Pinotepa Nacional, Oaxaca and IV in Panixtlahuaca, Oaxaca, Xadani, Puebla, Coacallco, with lesser shaking of II-III in Hidalgo and in the state of Mexico at Lopez Mateos, Tlalnepantla,, Vista Hermosa, Totoltepec, Ecatepec, Metepec, Naucalpan, Buenavista, Mexico City, Nezahualcoyotl, Los Reyes, Xico; in La Antigua, Antigua; in Puebla at Cuautlancingo, Cholula, Pueble, Tlaxcalancingo, Tianguismanalco, Ocoyucan; in Jojutla and Tilzapotla, Morelos; in Tierra Blanca, Veracruz; in Guerrero at Acapulco, Tlapa, and in Oaxaca at Puerto Escondido, Xoxocotlan, San Antonio de la Cal, Santa Lucia del Camino, Telistlanhuanca, Mital, Pochutla, Huajuapan, Huatulco. The aftershock of M 5.9 followed an M 4.2 minutes earlier. These occurred within about 15 minutes of local solar midnight, an hour when tidal stresses can be maximized and were probably enhanced by this stress." (February 19, 2018)

   

The earthquake in Oaxaca had been expected at this time with the full moon and lunar eclipse maximized near this location as noted in previous issues of this summary:

 

"The full moon will arrive on March 14, 2025 at 06:59 UT. This will entail a total lunar eclipse visible in the Pacific, Americas, Western Europe and Africa with maximum eclipse near 0N 105W near the Galapagos Islands. Longitudes near local solar noon are near 105W while those at solar midnight are near 75E. These include in the west portions of the North-east Pacific Rise, western Mexico and central North America; in the east areas of central or southeastern Asia and Sumatra  are included in this longitude zone. These are the areas most likely to see significant tidal triggering with this full moon and eclipse. As these include limited areas of high seismicity the likelihood of a major earthquake within about 4 days of March 14 would normally be deemed moderate to low. But this full moon could coincide with a major geomagnetic storm and this may help promote a strong to major earthquake at this time most likely in the region of western Mexico or near the antipode in southeastern Asia." (March 10-14, 2025)

 

and

 

 

"A series of moderate earthquakes occurred in a path across Guatemala, and Oaxaca, Chiapas and Guerrero, Mexico today. This volcanism is at the third node (120 degrees) from landfall of TC Alfred and was probably promoted by energy from that source.

 

These earthquakes in eastern Mexico and Guatemala are occurring along the antipode to TC Ivone as expected in previous issues of this summary:

 

"TROPICAL CYCLONE IVONE  (24S)                   

 

----  -------  ----------  --------  -----  ------  -------  ---------------

TC    IVONE    2025-03-10  00:00 UT  17.2S   83.1E  060 kts  South Indian Ocean  

 

Tropical Cyclone Ivone  (24S) continued today in the area of the south Indian Ocean with winds up to 60 kts.  It is expected to track to the south and west over the next several days. The antipode of this storm today is at 16N 97W in Oaxaca Mexico. This is a seismic area and is likely to see seismic enhancement as TC Ivone is near the antipode. The areas of Chiapas and Oaxaca are under a moderate seismic for the duration of Ivone at the antipode." (March 8-10, 2025)

 

This series began with an eruption of Volcan de Fuego near Alotenango, Guatemala two days ago and has caused the evacuation of 300 families and possible evacuation of up to 300,000 as the eruption continues. Another volcano in danger of eruption along this path of westward moving seismicity is Popocatepetl north of Mexico City, which is likely to see increased volcanism in the next two days.

 

This series is at the antipode to TC Ivone and near the third node (120 degrees) from the landfall of TC Alfred and was probably promoted by energy from those sources." (March 10-12, 2025)

 

Forecasts 170534 and 170535 had expected today's event within about 200 km was

likely around March 14, 2025.

A widely felt earthquake also occurred in east-central Italy with M 5.0. It occurred near Lesina, Italy. NEIC reported maximum intensity IV in Apulien, Italy at Bari, Foggia, Vieste, with III in Adelfia, Alberobello, San Giovanni Rotondo, amd II-III in Mandello del Lario, Lombardei and Piedimonte Matese, Campania. EMSC reported light to moderate shaking in Italy at San Martino in Pensilis, Vico del Garano, Lucera, Foggia, Vasto, Scerni, Paglieta, Gossacesia, Canosa di Puglia, Chieti, Pescara, Disceglie, Scafa, Montesilvano, Avellino, Sulmona, among others. Felt lightly as far as 300 km in Bosnia and Herzegovina, Montenegro, Albania, Croatia, western and northern Italy. The last earthquake of M>=5 within about 200 km of this epicenter in east-central Italy occurred as an M 5.5  on March 27, 2021 and prior to that an M 5.3 on August 16, 2018. At the time this summary noted:

 

 

"An earthquake of M 5.5 in the Adriatic Sea was widely felt in Italy today. NEIC reported maximum intensity IV in Italy at Santa Maria, Imbaro and Trani Apulien and II-III in San Marco in Lamis Apulien, Termoli, Foggia, Barietta, Francavilla al Mare, Ripa Teatina, Pescara and Montesilvano, Abruzzen. This is the strongest earthquake within about 200 km of this epicenter since a similar M 5.5 northwest of this on March 29, 2003. The largest earthquake in the area in the past 30 years was an M 6.0 on September 5, 1996." (March 27, 2021)

 

and

 

"An earthquake of M 5.3 in southern Italy today continued the moderate quakes in that area. No major damage has been associated with these events over the past several days. Today's M 5.3 was reported in Abruzzen, Italy at Sal Salvo, and San Vito Chietino and IV in Torrevecchia Teatina, Lentella, Campomarino, Casalbordino, with intensity II-III in Agnone, Molise; San Severo, Apulien, and in Abruzzen at Campo de Giove and Pescara and in general within about 150 km of the epicenter." (August 16, 2018)

 

Today's event in Italy is near 144 degrees from the landfall of TC Alfred in  Australia and, like the M 4.4 in Naples, Italy, yesterday may have been  promoted by energy from that source. An M 3.5 aftershock of the Naples activity occurred today and was felt in Naples, Portici and Ercolano, Italy.

 

Forecasts 170629 and 170350 had expected enhanced seismicity Italy was likely in mid-March.

NEIC reported this earthquake of M 4.0 in east-central Italy was felt with  intensity up to II-III in the area(s) of east-central Italy at Frascati, Lazio.

 

The strongest earthquake in the U.S. or Canada today was an M 4.4 off the west coast of the island of Hawaii. NEIC reported it was felt with intensity up to IV with III felt in Hawaii at Captain Cook, Hawi, Holualoa, Honaunau, Honokaa, Kahuku, Kailua, Waikoloa, Kailua Kona, Kamuela, Kealakekua, Naalehu, Pahoa, Pepeekeo, Mililani and II in Hilo, Honomu, Kapaau, Laupahoehoe, Paauilo, Papaikou, Kula, Wailuku, Honolulu. EMSC reported light shaking in Hawaii at Kailua, Honokaa. The last earthquake of M>=4.4 in Hawaii occurred on November 5, 2024 with M 4.8.  Enhanced seismicity in Hawaii had been expected at this time as it is nearly antipodal to TC  Jude as noted in previous issues of this summary:

 

"Tropical Cyclone Jude (25S) continued today in the area of the Mozambique with winds up to 50 kts.  It is expected to track to the south and west over the next several days. The antipode of this storm today is at 17N 140W in the north Pacific and is aseismic. Further seismic triggering from TC Jude is unlikely at this time. Moderate earthquakes today of M 3.5 and 3.7 in Hawaii may have been promoted by energy from this source." (March 10-14, 2025)

 

This event in Hawaii occurred about 6 minutes after the M 5.6-5.9 in Oaxaca, Mexico, about the time it takes the p-wave to traverse the distance between these two epicenter. P-wave triggering is a possibility in this case.

NEIC reported the M 6.0 in the South Sandwich Islands may have been felt with intensity up to V in the epicentral area of the South Sandwich Islands although there were no reports of felt intensity for this event. The last earthquake in the South Sandwich Islands within about 200 km of this epicenter with M>=6.0 occurred on January 1, 2025 with the last major geomagnetic storm. At the time this summary noted:

 

"The strongest earthquakes in the world today occurred in the southern oceans.

These included an M 6.1 in the South Sandwich Islands and an M 5.5 in the

Balleny Islands south of New Zealand and an M 5.2 in the Tristan da Cunha area of the South Atlantic. None of these were reported felt in their remote epicentral areas. The event in the South Sandwich Islands occurred within a few minutes of local solar noon and was probably promoted by strong tidal stresses associated with the super new moon of December 30

...

 

The last earthquake of M>=6.1 in the South Sandwich Islands occurred as an M 6.3 on October 25, 2022. A great M 8.1 hit the region on August 12, 2021." (January 1, 2025)

 

It is of some interest that the event on January 1, 2025, like that of today occurred with the strongest geomagnetic storms of the current year as described in the previous issue of this  summary:

 

 

"This planetary AP of 42 is the highest AP index since it reached AP of 86 on

January 1, 2025. This could be followed in the next several days by a moderate increase in global seismicity." (March 14, 2025)

 

 

Today's  event in the South Sandwich Islands occurred at the maximum of today's geomagnetic storm at a high latitude and near local solar midnight and may have been promoted by strong tidal stresses with the full moon and lunar eclipse today. These maximize near this hour.

 

 

Forecast 170750 had expected today's event within about 150 km of this epicenter was likely around March 17, 2025.

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.

FULL MOON AND LUNAR ECLIPSE BRING FRESH SEISMICITY

 

EARTHQUAKE SUMMARY FOR MARCH 13, 2025

 

 

An M 5.1 occurred in the Himachal Pradesh area near the Intia-Pakistan border today. NEIC reported it was felt with maximum intensity V in India at Chamba, Sundarnagar, IV in Hamirpur, Manali, Palampur, Shimla; in Jammu and Kashmir at Anantnag, Badami Bagh, Bhaderwah, Kistwar, Udhampur and in Punjab at Kharar, Rupnagar, with lesser shaking within about 300 km of the epicenter. EMSC reported strong shaking with people running from their homes in Zanskar, Udaipur, and lesser shaking i Gandoh, Doda, Jammu and Kashmir, Manali, Palampur, Kullu, Pathankot, Mandi, Char-e-Sharif, Bagh Hussain, Zainakote, Dooro Budgam, Sialkot, Pattan, Mirpur and in Pakistan with light shaking in Islamabad. This event occurred at 76 East longitude near local solar midnight and was likely promoted by strong tidal stresses with today's full moon. These tidal stresses maximized at this longitude and time as noted in previous issues of this summary:

 

 

"The full moon will arrive on March 14, 2025 at 06:59 UT. This will entail a total lunar eclipse visible in the Pacific, Americas, Western Europe and Africa with maximum eclipse near 0N 105W near the Galapagos Islands. Longitudes near local solar noon are near 105W while those at solar midnight are near 75E. These include in the west portions of the North-east Pacific Rise, western Mexico and central North America; in the east areas of central or southeastern Asia and Sumatra  are included in this longitude zone. These are the areas most likely to see significant tidal triggering with this full moon and eclipse. As these include limited areas of high seismicity the likelihood of a major earthquake within about 4 days of March 14 would normally be deemed moderate to low. But this full moon could coincide with a major geomagnetic storm and this may help promote a strong to major earthquake at this time most likely in the region of western Mexico or near the antipode in southeastern Asia." (March 10-13, 2025)

 

Forecast 170596 had expected this event within about 200 km was likely around

March 16.

The strongest earthquake in the U.S. or Canada today was an M 5.1 in north-central Alaska near Ambler. It was not reported felt in this remote area but was probably felt with intensity up to VI in the epicentral area. This earthquake occurred within minutes of local solar noon and was probably promoted by tidal stresses with today's full moon and lunar eclipse which maximize near this hour and were noted in previous issues of this summary (see above).

 

This event in northern Alaska could have been promoted by SFE associated with

flare 9740 which began five minutes before the quake and for which SFE were maximized at this event of local solar noon in northern Alaska. Data from SWPC for this flare follow.

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.
