The Atlantic Hurricane season may be beginning after a long period of unusual inactivity. This
is probably due to a dramatic cooling of the central Atlantic over the past
several months. Cooling of the waters in this area can dampen strong storm formation.
This cooling is now beginning to dissipate leading to warmer equatorial waters. No major storms
are expected in this environment. The only cyclones in the Atlantic or Gulf of Mexico
at this time are Depression Six north of Oaxaca and Chiapas, Mexico. Thisis a minor system located north of Guatemala and the area of the Yucatan, Mexico.
While small this could enhance seismicity in Guatemala and eastern Mexico in the nest several days. It is currently located near
22N 95W. Storm systems in the Atlantic at 12N 32W and 13N 43W are expected
to track to the west leading to possibly increased seismicity in the Caribbean

An aftershock of M 5.0 was reported by NEIC to have been felt with intensity II-III in the Philippines at Manila and in Taytay, Rizal, Tagalog.
It is likely that this activity was promoted by landfall in the region today of
Tropical Storm Yagi as proposed in previous issues of this summary:
" TC YAGI (12W) formed today east of Leyte and Samar, Philippines with winds up to 55 kts. This system is currently located at 16N 122E with winds up to 55 kts and heading to the west. Landfall in the central Philippines could bring enhanced seismicity to that area of the Philippines.
and
TS YAGI (12W) continued today east of northern Luzon Philippines with winds up to 70 kts. This system is currently located at 19N 120E with winds up to 70 kts and heading to the west. Landfall in the central and northern Philippines could bring enhanced seismicity to that area of the Philippines. It is then likely to reach typhoon levels as it moves into eastern China." (September 2-3, 2024)

The Atlantic Hurricane season may be beginning after a long period of unusual inactivity. This
is probably due to a dramatic cooling of the central Atlantic over the past
several months. Cooling of the waters in this area can dampen strong storm formation.
This cooling is now beginning to dissipate leading to warmer equatorial waters. No major storms
are expected in this environment. An unnamed system is currently located at about 16N 75W
and could impact Caribbean seismicity in the next several days.
A second system is forming off the west coast of North Africa. This is currently located
at 13N 27W and moving to the west but is not expected to impact regional
seismicity at this time. A third system is located at 15N 48W. These
are expected to track to the west and impact the Caribbean in about a week.

The strongest earthquake in the world today was an M 6.4 in the northern Solomon Islands, Papua New Guinea.
NEIC reported it was felt with damage in Panguna with intensity VIII.
A tsunami was not expected nor observed. No tsunami warning was issued. A moderate foreshock hit the area several days ago and was addressed in this
summary as:
"An unusual earthquake occurred today with M 4.5 in the Bougainville Region, PNG.
While this region is typically quite active with events of M>=5.5 often occurring
nearly monthly, the last such event occurred as an M 5.8 on March 8, 2023 and
it may be overdue for another." (August 29, 2024)
Today's M 6.4 may have been promoted by strong tidal stresses associated with
the upcoming new moon of September 3 as it occurred at the longitude of
maximum stress with this alignment as noted in previous issues of this summary:
"The New Moon will arrive at 01:55 UT on September 3, 2024. Longitudes which will be at local solar midnight at this time are near 30 West while those at local solar noon are near 150 East. These zones include the central Atlantic and Iceland and western Europe in the west and the Kuril Islands, Japan and portions of eastern Indonesia and the Vanuatu Islands in the east. These areas are the most likely to see tidal triggering in the next week. Such events often occur near local solar midnight and noon. A major earthquake is considered likely with this new moon in the 10 days." (August 28-September 2, 2024)
This earthquake in New Guinea is located on the geomagnetic equator. It occurred at
the maximum of an M-class solar flare and may have been promoted by energy
(SFE) associated with that flare (#8490). SWPC data for this flare follows:
Flare # START MAX END CLASS DATE Flux (Jm-2)

The strongest earthquake in the world today was an M 6.1 off the coast of El Salvador. NEIC reported it was felt with intensity up to IV in El Salvador in La Libertad, Zaragoza, Nuevo Cuscatlan, Nueva San Salvador, Antiguo Cuscatlan, Guaymango, Ayutuxtepeque, Quezaltepeque, Apopa and Guazapa and in portions of Guatemala.
EMSC reported strong shaking in El Salvador at San Salvador, Nueva San Salvador, Apopa, and in Guatemala at Colonia Valles De Vista Hermosa, Colonia Valle Dorado, La Floresta, Guatemala City, No major damage or tsunamis were associated with this earthquake. Several aftershock
and foreshocks were not reported felt except for an M 4.2 felt lightly in San Salvador, Santa Ana, El Salvador and in Guatemala City, Guatemala. This event was probably promoted by tidal effects as it lies near the longitude
of maximum tidal stress with the previous full moon as noted in previous issues
of this summary:
"The full moon arrived at 18:26 UT on August 19, 2024. Longitudes which were at local solar midnight at this time are near 85 East while those at local solar noon are near 95 West. These include areas of central North America and the East Pacific in the west and central Asia including China, India, Nepal in the East. These areas are most likely to see moderate tidal triggering at this time. Tidal enhancement of regional seismicity is possible in many areas, however, a major earthquake associated with this new moon is considered possible in the next week by this report." (August 20-25, 2024)
Today's event occurred at the height of a strong geomagnetic storm - the strongest
in the past month and may have been promoted by geomagnetic effects. This is the strongest earthquake near El Salvador since an M 6.5 on July 19, 2023.
At the time this summary noted:
"The strongest earthquake in the world today was an M 6.5-6.6 in El Salvador, Central America. NEIC reported it was felt with maximum intensity VIII in El Salvador at Chirilagua, San Miguel; VII in Concepcion, Batres Usulutan, VI in Intipuca La Union; V in Usulutan, IV in San Aleo, San Miguel, Santiago de Maria, San Luis la Herradura La Paz and lesser shaking in El Vijo and Ciudad Barrios, San Miguel.
This event was preceded by several light foreshocks.
Enhanced activity in this region had been expected at this time as it lies near the
longitude of maximum tidal stress with this new moon as discussed previously
in this summary ...
The new moon was expected to promote seismicity in Central America near 90 West
longitude (see tidal forecast above). Two groups of earthquakes today indicated
by their timing to have been triggered by tidal stresses with this alignment.
They occurred near local solar midnight in an area where strong tidal stresses
were expected with this new moon in the area off the coast of El Salvador (M 3.9, 3.9)..." (July 19, 2023)

A moderately strong earthquake of M 5.4 was widely felt in Portugal today. It occurred
near the antipode of an earlier M 6.9 in Tonga and may have been related to
antipodal focusing of seismic energy at the antipode of that epicenter. NEIC reported
the earthquake in Portugal was felt with maximum intensity VII in Lisbon, Portugal at Benedita Lisboa e Vale do Tejo and VI in Portugal at Ponte Norte, Sines Alenteho with V in Trafaria Lisboa e Vale do Tejo, Santa Barbara de Nexe, Monte Redondo, Moita, Loures, Castro, Carregado, Bucelas, Bombarral, Arrentela, Alferrarede, Lisbon, and with lesser shaking throughout Portugal and portions of Spain.
EMSC reported a possible minor tsunami with maximum shaking in Portugal near the
towns of Sines, Zambujal de Cima, with a great deal of noise. Euro Weekly News reported no major damage or injuries with this earthquake.
The last earthquake located near Portugal with M>=5.4 occurred more than 35 years ago. The only
comparable event in the past 35 years occurred with M 5.4-5.5 on December 17, 2009 and January 10, 2006.
At the time this summary noted:
"A moderately strong earthquake of M 5.7-6.3 hit west of Gibraltar today and
was felt widely in Portugal, Spain and Morocco. Spain's Seismological Institute
gave the M 6.3 while NEIC gave M 5.7. The most likely magnitude given the
widely felt region is M 6.3. Reports from NEIC often underestimate the magnitude
of larger events initially and give larger values at a later time. NEIC reported maximum intensity
VI in Odemira, Alentjo, Portugal and V in Portugal at Boliqueime, A dos Cunhadoa, Aljezur, Azambuja, Baixa de Banheira,
Castanheira do Ribatejo, Grandola, Lagoa, Luz, Malveira, Mealhada, Monchique,
Montenegro, Pampilhosa, Portimao, Porto de Mos, Soure, Queijas, Rio Maior, Serpa, Serta,
in Spain at Caceres, and in Morocco at Khouribga and Settat. Intensity IV was generally
felt within about 300 km of the epicenter; III within about 500 km and II within
500-700 km from the epicenter. Spanish media reported the quake was also felt
in Seville, Cordoba and Huelva, Spain. The epicenter is located near the presumed
epicenter of the great Lisbon earthquake of November 1, 1755 which destroyed
along with a tsunami much of the built coast of Portugal." (December 17, 2009)
The strongest earthquake in the world today was an M 6.9 followed by an M 6.2
aftershock in Tonga. These events occurred within minutes of local solar noon
and were likely triggered by tidal and/or geomagnetic stresses which maximize
near this hour. NEIC reported this earthquake was felt with maximum intensity
V in Tonga at Pangai with IV in Tamakautoga, Niue, Nuku'alofa, Haveloloto, and III in Avatele, Alofi and Neiafu Vava'u Tong with slight shaking II in American Samoa.
No tsunami was expected by EMSC which reported the quake was felt in Tonga at Nuku'aofa.
A regional foreshock of M 4.4 was felt with intensity III in Neiafu Vava'u, Tonga
half a day earlier. The last earthquake within about 250 km of today's epicenter
in Tonga with M>=6.9 occurred as an M 6.9 on July 2, 2023 and prior to that on November 11 and 12, 2022
with M 7.0 and M 7.3. At the time this summary noted:
A strong earthquake of M 6.9 shook areas of northern Tonga today. NEIC reported maximum shaking IV in Tonga at Neiafu Vava'u and Pangai, Ha'apai and Upolu, Samoa with intensity II-III in Samoa at Manono Uta, Maninoa, Aufaga, American Samoa and in Tonga at Nuku'alofa, Haveloto, and Tofof-Koloua, Tongatapu.
Tonga and Fiji have been active in the past several months including an M 7.2 on
June 15, 2023 and an M 7.6 on May 10, 2023. Today's earthquake follows a regional enhancement in Fiji and Tonga which was
addressed in the previous summary as:
"A series of earthquakes also continued in the area of the Tonga Islands. The strongest
of these was an M 5.6 in the northern Tonga Islands.
This earthquake occurred at the peak output of flare 6630 - an M1.1 class solar flare
and the strongest flare of the day. The earthquake occurred within minutes of
local solar noon when immediate flare effects (SFE) are most likely to
trigger earthquakes. It is likely it was triggered by SFE. This could indicate
that a stronger earthquake in this area is likely at this time especially
since the area is at the maximum longitude for tidal effects from the full
moon of July 3 (2023)" (July 3, 2023)
A moderately strong earthquake of M 5.8 also occurred south of Panama today. NEIC reported it was felt with damage and intensity VIII in Panama at Cerro Sombrero Ngobe Bugle, and lesser shaking in Chiriqui (IV) at Boquete and Volcan and in San Miguelito, Panama.
EMSC reported moderate shaking in Panama at Puerto Armuelles, David, Cahuita.
This event occurred within minutes of local solar midnight and may have been
promoted by strong tidal stresses which maximize near this hour.
This is the strongest earthquake near Panama within about 250 km since an
M 6.3 on April 4, 2023. At ths time this summary noted:
"The strongest earthquake in the world today was an M 6.7 south of Panama. NEIC reported maximum intensity VIII in Cerro Sombrero, Panama withIV in Remedios; V in Guarumal; IV in Pedregal, David, Berba, Chiriqui and less shaking in Horconcitos, Quitno, Los Algarrobas, Panama among others.
This is the strongest earthquake in the area south of Panama within about 250 km

It was a quiet day in global seismicity today. The only notable earthquake, and
the largest event in the world was an M 5.0 in Greenland north of Norway. This
continued enhanced seismicity in in the area of Greenland as reported in
the previous issue of this summary:
"The largest and most unusual earthquake in the vicinity of the U.S. or Canada
today was an M 4.5 in Western Greenland. A series of events of M 4.5-4.6
hit this area of Greentland in January, 2022 and December, 2022 and January 2023 but
the only event in the area with significantly larger magnitude in the
past 35 years was an M 5. on October 14, 1998." (August 10, 2024)

The most unusual earthquake in the world today occurred today as an M 4.4 in Romania.
NEIC reported this earthquake of M 4.4 in Romania was felt with intensity up to IV in the area(s) of Romania in Arad at Savarsin (V); Bata Birchis and Inew and in Deva Hunedoara, and in Cluj at Savadisla, Floresti, Cluj-Napoca, Apahida and as far as Bucharest.
EMSC reported moderate shaking in Romania at Varadia de Mures, Julita, Temeresti, Lugoj, Lipova, Buzard, Zabrani, Siria, Cicir, Horia, Bocsig, Santana, Arad among others.
This is the strongest earthquake Romania within about 200 km of this shallow
focus event since an M 4.5 on August 20, 2023 - an aftershock of an M 5.5 on February 14, 2023.
At that time this summary noted:
"No earthquakes of greater magnitude have occurred in southern Romania in
at least 35 years. The last earthquakes of M 5.5-5.6 within about 200 km
of today's epicenter hit west of this in Serbia on July 12 and 18, 1991.
This activity is at 145-150 degrees from the strong earthquakes in the
Tonga and Fiji areas in November and December, 2022 and at 105 degrees from
the M 6.8 in Argentina of January 20, 2023 and at 100 degrees from the M 7.6
in Michoacan, Mexico of September 19, 2022 and was probably
promoted by energy from those sources." (February 14, 2023)
