MODERATE QUAKES SHAKE FOX ISLANDS; TAUPO, NEW ZEALAND NEAR IDL

EARTHQUAKE SUMMARY FOR DECEMBER 1, 2022

The largest earthquake in the U.S. or Canada today was an M 4.8 in the Fox Islands, Aleutians, Alaska. NEIC reported it was felt in Unalaska, Alaska with intensity II. An M 6.1-6.2 earthquake hit near this epicenter on January 22, 2022, a regional aftershock of an M 6.8 on January 11, 2022. The last earthquake of M>=4.8 within about 100 km of this epicenter was an M 5.2 on June 8, 2022. Today's event of M 4.8 occurred within minutes of local solar noon and was probably promoted by tidal and geomagnetic stresses which maximize at this time. Today's mainshock occurred while a strong geomagnetic storm was peaking as noted in this summary below:

"The geomagnetic field saw minor storm conditions today. The AP level was 28. High latitudes saw major storm conditions with AP 51. Middle latitudes were at minor storm conditions with AP 28. This is the strongest geomagnetic storm since global AP reached 26 on November 3 and is likely to promote seismicity near the geomagnetic equator and at high latitudes in the next several days.

... The maximum disturbance in the geomagnetic field today occurred with KP 7 at 09:00 UT, December 1, 2022." (December 1-2, 2022)

Forecasts 148872 and 148590 had expected enhanced activity in this area of the Fox Islands was likely in late November or early December, 2022. This activity, like the swarm off Baja California is located at the fifth node (72 degrees) from the M 7.3 in Tonga of November 11, 2022 and was probably promoted by energy from that source.

The swarm of moderate earthquake near Taupo, North Island, New Zealand continued today. The strongest of today's events was an M 5.1 although GeoNet gave the magnitude considerably higher possibly up to M 6.2. The last earthquake near Taupo with M>=6.2 occurred with M 6.4 on December 7, 2012. GEONET reported this event of M 6.2 was felt with moderate intensity in the area northeast of Taupo. This earthquake was felt with light to moderate intensity throughout most of North Island. 9283 responded with felt information for this earthquake including 6235 who felt it with weak intensity and 2728 with light shaking; 289 moderate; 18 strong; 2 severe and 11 extreme. NEIC reported this earthquake of M 5.1 in North Island, New Zealand was felt with intensity II-III in the area(s) of North Island, New Zealand in Taupo, Tauranga, Bay of Plenty, Whakatane Bay, Hamilton Waikato, Napier, Hawke's Bay, Wanganui and Upper Hutt. Forecast 148933 had expected today's activity within about 100 km of this epicenter was likely around December 3, 2022.

The volcanic eruption at Mauna Loa, Hawaii continued today. The largest associated earthquake was an M 3.7. It was reported felt with intensity II-III in Pahala, Naalehu, Captain Cook, Volcano, Holualoa, Hilo, Paauilo, Kailua Kona and Pepeekeo among other communities. This earthquake occurred during the strongest solar flare of the day (M1.0, #6790). This is the strongest and first M-class flare observed since an M 1.6 on November 19, 2022.

Parameters for this flare are from SWPC:

A pair of light earthquakes also occurred today in Central New Mexico. These events of M 3.7 and M 2.7 were reported by NEIC to have been felt with intensity III in Socorro, New Mexico. The M 3.6 is the strongest earthquake within about 150 km of this epicenter since an M 3.7 exactly five years ago on December 1, 2017. Today's events occurred within minutes of local solar midnight and were likely promoted by strong tidal and geomagnetic stresses which maximize near this hour. Forecast 148508 had expected regional seismic enhancement to the west of this event was likely in late November. This epicenter is near 144 degrees from the M 6.8 in Sumatra of November 18 and many 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.

MODERATE QUAKES SHAKE IRAN AND NORTH ISLAND, NEW ZEALAND

EARTHQUAKE SUMMARY FOR NOVEMBER 30, 2022

A series of moderate shocks shook the Lake Taupo area of New Zealand today. The largest of these was an M 5.4 which was reported with intensity VIII in North Island New Zealand at Turangi; VII in Taupo, Waikato; V in Tokoroa; IV in Rotorua, Bay of Plenty and II in Hamilton. GEONET reported the M 5.6 was felt with moderate intensity in the area northeast of Taupo. This earthquake was felt with light to moderate intensity throughout most of North Island. 5440 responded with felt information for this earthquake including 2093 who felt it with weak intensity and 1564 with light shaking; 1151 moderate; 552 strong; 69 severe and 11 extreme. Several moderate aftershocks including those of M 4.5 were also felt in the Taupo area of North Island, New Zealand. These events of M 4.5 were reported by GEONET to have been felt with moderate intensity in the area northeast of Taupo. This earthquake was felt with light to moderate intensity throughout most of North Island. 758 responded with felt information for this earthquake including 218 who felt it with weak intensity and 306 with light shaking; 200 moderate; 24 strong; 3 severe and 7 extreme. GEONET reported an M 4.1 was felt with moderate intensity in the area northeast of Taupo. This earthquake was felt with light to moderate intensity throughout most of North Island. 391 responded with felt information for this earthquake including 196 who felt it with weak intensity and 153 with light shaking; 39 moderate; 3 strong; 0 severe and 0 extreme. The initial shocks occurred near local solar midnight while the M 4.1 occurred near local solar noon. These are times of maximum geomagnetic and tidal effects and these probably helped promote this activity in North Island, New Zealand. The M 5.6 is the strongest earthquake within about 200 km of these epicenters since an M 6.1 on October 30, 2018 and an M 6.3 on December 7, 2012. Forecasts 148662 and 148663 had expected this activity within about 25 km was likely towards the end of November, 2022. This activity is at 103 degrees from the M 6.8 in Panama of October 20, 2022 and was likely promoted by energy associated with that source.

The strongest earthquake in the world today was an M 5.7 in Southern Iran. NEIC reported it was felt with maximum intensity IV in the United Arab Emirates at Ujman and Ash-Shariqah and III in Ras Al Khaimah and Dubai. The M 5.6-5.7 is the strongest earthquake in Southern Iran within about 200 km of this epicenter since an M 6.0 on July 1, 2022 and is the largest aftershock to date of that event. At the time this summary noted in this regard:

"A series of strong earthquake did damage in southern Iran today. Reuters News reported from Dubai that these earthquake, including an M 6.1 and M 6.3 killed at least five people and injured at least 50 in Southern Iran. The earthquakes occurred near local solar midnight and may have been promoted by high tidal stresses associated with the new moon of June 29. The village of Sayeh Khosh in Hormozgan Province near the southern coast of Iran was devastated. All the victims died in the first earthquake as people were out of their houses when the later strong quakes hit. Many of the injured were hospitalized. Internet pictures showed flattened houses in the region of Southern Iran. NEIC reported these earthquakes in southern Iran and the United Arab Emirates were felt with maximum intensity V in Bandar Abbas, Hormozgan, Iran and IV in Gheshm and IV in Ujman, Ash-Shariqah and Dubai, United Arab Emirates." (July 2, 2022).

Forecast 148465 had expected today's events were likely within about 25 km

of these epicenter most likely to occur around November 30, 2022. This event is near 104 degrees from the M 7.0 in the Solomon Islands of November 22, 2022 and was probably promoted by energy from that source.

Moderate aftershocks continued to shake the region of Alberta, Canada today. These included an M 5.4 and 4.4 among others after the M 5.3 early on November 30. This was reported in the previous issue of this summary as:

"The largest earthquake in the U.S. or Canada today was an M 5.3 in Alberta, Canada. The mainshock was felt widely in Alberta with maximum intensity IV in Peace River, Falher, High Prairie, Manning, Fairview, and III in Grimshaw, Valleyview, Slave Lake, Spirit River and Sexsmith. It was followed by an aftershock of M 4.5 which was reported felt with intensity IV in Alberta at Slave Lake, Whitecourt and II-III in Peace River, High Prairie, Fairview, Grande Prairie, Athabasca, High Leven and Wood Buffalo and in Dawson Creek, British Columbia. Foreshocks of M 4.6 and 4.9 to the M 5.3 was felt in the same area as the mainshock with maximum intensity IV in Alberta at Peace River, High Prairie, Spirit River, Sexsmith, Slave Lake and in Dawson, BC. This activity is a continuation of events which hit the area on November 22-24, 2022. That included an M 4.5 which previous to the M 5.3 today was the largest earthquake in the area in more than 35 years as noted in this summary at the time:

"The strongest earthquake in the U.S. or Canada today was an M 4.5 in Alberta,

Canada. This event occurred within minutes of local solar midnight and was probably promoted by strong tidal stresses with today's new moon. These maximize near local sola midnight. The mainshock was followed by an M 3.8 aftershock near Reno, Alberta. This is the strongest earthquake within about 200 km of this epicenter in Alberta, Canada in at least 35 years. Smaller quakes hit about 200 km to the south of this as an M 4.2 on January 12, 2016 and an M 4.0 on June 13, 2015. Forecasts 148296 and 148582 had expected enhanced seismicity in this area was likely around November 16-21. This epicenter is at 120 (node 3) degrees from the M 6.9 in Sumatra of November 18, 2022 and is likely to have been promoted by energy from that source. It is also near 100 degrees from the M 7.6 in New Guinea of September 10; the M 7.0 in Fiji of November 9 and the Loyalty Islands M 7.0 of September 14, 2022 and may have been promoted by energy from those sources." (November 25, 2022)

Following is a listing of events of M>=4 in this series in the past day. A more extensive listing of events of M>=3 in the region can be found in this summary under "WESTERN CANADA" section below. These epicenters, like those off the coast of Baja California are located at 100 degrees from the M 7.6 in New Guinea of September 10, 2022 and the events in Tonga and Fiji M 7.0 of November 9 and were probably promoted by energy from those sources. This is reflected in the earthquake distance chart in the "DISTANCE" section of this summary where a strong peak occurs at 100 degrees distance.

MODERATE SEISMICITY AT HIGH LATITUDES WITH GEOMAGNETIC STORM

EARTHQUAKE SUMMARY FOR NOVEMBER 29, 2022

The strongest earthquake in the world today was an M 5.5 in the Reykjanes Ridge,

North Atlantic Ocean region. It was followed by a series of moderate aftershocks, none of which were felt in this remote area. This, and a strong earthquake of M 5.3 near the same latitude in Alberta, Canada today appear to have been promoted by a minor geomagnetic storm of the past two days which maximized today as noted in this and previous issues of this summary as:

"The geomagnetic field saw minor storm conditions today. The AP level was 25. High latitudes also saw minor storm conditions with AP 43. Middle latitudes were at active conditions with AP 20. This is the strongest geomagnetic storm since global AP reached 26 on November 3 and is likely to promote seismicity near the geomagnetic equator and at high latitudes in the next several days." (November 28-30, 2022)

The M 5.5 is the largest in a series of earthquakes near this epicenter which began with an M 5.7 on September 26, 2022 and included other shocks of M 5.7 on September 29 and M 5.9 on October 1. The last moderate event in the region occurred on November 3, 2022 with M 5.4. The initial shocks in today's series occurred near local solar noon and may have been promoted by strong tidal stresses which maximize near this hour. Forecast 148594 had expected enhanced seismicity within about 25 km of this epicenter was likely at the end of November. This activity is near 144 degrees from the major earthquakes in Fiji and Tonga of mid-November and at the sixth node (60 degrees) from the Panama and Michoacan Mexico quakes of September and October was probably promoted by energy from those sources.

Another area of the North Atlantic which has been active in recent days is the Azores. An M 4.8 aftershock to an M 5.9 on November 28 hit the area today. At the time of the M 5.9, this summary noted the unusual character of this event as:

"The strongest earthquake in the world today was an M 5.9 in the Azores, Portugal. It was not reported felt in this area. This is the strongest earthquake in the Azores region within about 250 km of this epicenter in at least 35 years. An M 6.1 occurred about 300 km to the south west of this epicenter on January 4, 2022 and an M 5.9 was located about 250 km to the southwest on November 4, 2009. The strongest earthquake in the past 35 years near 250 km from today's epicenter was an M 5.9 30 years ago on November 30, 1992. Today's event occurred within minutes of local solar midnight and may have been promoted by tidal stresses which maximize near this hour. Forecast 148500 had expected today's event was likely around November 22, 2022 within about 100 km of today's epicenter. This epicenter is located at 142-145 degrees from recent major earthquakes in Tonga and Fiji and was probably promoted by energy from those sources." (November 28-29, 2022)

The largest earthquake in the U.S. or Canada today was an M 5.3 in Alberta, Canada. The mainshock was felt widely in Alberta with maximum intensity IV in Peace River, Falher, High Prairie, Manning, Fairview, and III in Grimshaw, Valleyview, Slave Lake, Spirit River and Sexsmith. It was followed by an aftershock of M 4.5 which was reported felt with intensity IV in Alberta at Slave Lake, Whitecourt and II-III in Peace River, High Prairie, Fairview, Grande Prairie, Athabasca, High Leven and Wood Buffalo and in Dawson Creek, British Columbia. Foreshocks of M 4.6 and 4.9 to the M 5.3 was felt in the same area as the mainshock with maximum intensity IV in Alberta at Peace River, High Prairie, Spirit River, Sexsmith, Slave Lake and in Dawson, BC. This activity is a continuation of events which hit the area on November 22-24, 2022. That included an M 4.5 which previous to the M 5.3 today was the largest earthquake in the area in more than 35 years as noted in this summary at the time:

An unusual M 4.1 also occurred today in the Northwest Territories of Canada near Prince Patrick Island. It was not reported felt in this remote region. This is the largest earthquake within about 300 km of this epicenter since an M 4.2 on February 5, 2017 and prior to that an M 4.9 on May 18, 2012. Forecast 148616 had expected this event about 300 km to the east of this epicenter was likely around November 24. This event, like Hawaii is located at the fifth node (72 degrees) from the M 6.9 in Panama of October 20 and at the sixth node (60 degrees) from the Michoacan, Mexico quake of September and was probably promoted by energy from those sources.

An earthquake of M 4.9 also shook Trinidad and Tobago today. NEIC reported it was felt with intensity V in Mucurapo, Diego Martin and II-III in Port of Spain, Changuanas, San Fernando, Saint Joseph, Siparia, Tunapuna and Sangre Grande, Trinidad and Tobago. This is an active area but the last event in the area within about 200 km of today's epicenter at shallow focus of equal or greater magnitude in Trinidad and Tobago was an M 5.1 about 200 km east of this epicenter on January 29, 2022. Forecast 148450 had expected today's event within about 100 km of this epicenter was likely at the end of November. Intermediate focus events hit near today's epicenter most recently on July 14, 2022 (M 5.4) and April 6, 2022 (M 4.9).

An earthquake of M 4.8 was widely felt in the Aegean Sea of Greece today. It follows several moderate earthquakes felt in this area in the past several days. NEIC reported it was felt with maximum intensity IV in Attiki, Greece at Psikhikon and Zefirion and II-III in Nea Makri, Kimi, Ewoia, Kifisia, Vrilissia, Ayia Paraskevi, Khalandrion, Kholargos, and Ayioi Anaryiror. Two foreshocks hit the area earlier in the day with M 4.4 and 4.6 and were reported in the previous issue of this summary as:

"NEIC reported this earthquake of M 5.0 in the Aegean Sea, Greece was felt with intensity IV-V in the area(s) of the Aegean Sea, Greece in Ayios Loukas, Kentriki Ellada, Zarakes, Karistos, Metamorfosi and II-III in Kato, Peuki, Limin Markopoulou, Kholargo, Attiki and Gaurio Kiklades." (November 29, 2022)

The last earthquake in the Aegean Sea with M>=4.8 occurred about 200 km north of today's epicenter as an M 5.3-5.5 on January 16, 2022, the only such event in the past two years in the region. Forecast 148470 had expected today's activity was likely within about 50 km of these epicenters around November 25, 2022. This activity is located at 104 degrees from the M 7.6 in Michoacan, Mexico of September 19, 2022 and was probably promoted by energy from that source.

The eruption of Mauna Loa volcano in Hawaii continued today and was joined by minor eruptions at other volcanoes on the island of Hawaii, including Kilauea. This is the first times since 1984 that both volcanoes were erupting simultaneously. Lava fountains up to 200 feet high occurred with today's eruption and were well documented by photographers. There are built areas around Mauna Loa and a shift in direction of lava flows could potentially affect these areas. Emergency evacuation plans could be implement in that case. The strongest earthquake in the eruptive zone today was an M 4.0. NEIC reported it was felt with maximum intensity IV in Hawaii at Volcano and Papaikou with intensity II-III in Hawaii National Park, Naalehu, Captain Cook, Pahoa, Mountain View, Hilo, Kurtistown, Keaau among others. The previous issue of this summary detailed more the initial stages of this eruption. Forecast 148457 had expected this activity in Hawaii was likely at the end of November.

A moderate earthquake of M 4.2-4.5 in southern Puerto Rico also shook that Island today. NEIC reported it was felt with maximum intensity V in Guayanilla and IV in Yauco, Penuelas, Ponce, and II-III in Adjuntas, Guanica, Lares, San German among others. This is an aftershock of the M 6.4 which hit the area with much damage in the Ponce region on January 7, 2020. The last earthquake in this area of Puerto Rico of equal or greater size was an M 4.5 more than a year ago on July 18, 2021. Forecast 148448 had expected today's event was likely around November 27-30 within about 100 km of these epicenters. This activity is near 144 degrees from the major earthquake in Sumatra of November 18 and was probably promoted by energy from that source.

MAJOR ERUPTION AT MAUNA LOA, HAWAII

EARTHQUAKE SUMMARY FOR NOVEMBER 28, 2022

The anticipated eruption of Mauna Loa, Hawaii began today. This is the first major eruption of Mauna Loa since January 7, 1983. This eruption started near local solar noon on the island of Hawaii and was probably brought on by many factors including strong tidal stresses which maximize near this hour. Hawaii is also ideally located with respect to recent major earthquakes for constructive interference of energy to yield far-field triggering from these sources at this time as noted in the previous issue of this summary:

"The imminent eruption of Mauna Loa in Hawaii is likely in the next several days. This volcano has shown signs of this eruption for weeks but is located at significant nodal positions from recent major earthquakes which may tip the balance in the eruption. These include the series of earthquakes in Tonga and Fiji of November 9-12, 2022 (52 degree - node 7); the Solomon Island of November 22, 2022 (also 52 degrees - node 7); Michoacan, Mexico (52 degrees - node 7),

Sumatra of M 6.9 November 18 (103 degrees - node 7) all of these at node 7 can see their energy constructively interfere in Hawaii especially with the new moon influence. Hawaii is also at the fifth node (72 degrees) from Panama where an M 6.9 occurred on October 20, 2022 and near the sixth node (60 degrees) from the M 7.6 in New Guinea of September 10, 2022." (November 27-28, 2022)

The influence of the seventh node triggering can be seen in the distance between major earthquakes and earthquakes today in the "DISTANCE" section of this summary. Note the very strong peak in the distance graph at 51-52 degrees (seventh node is 51.4 degrees) and the strong peak at 103 degrees (also 7th node X2). Strong peaks at 90, 72, 60 and 45 show seismicity influences at other nodes. The last significant activity in Mauna Loa occurred with the full moon of November 8 and was noted in this summary at the time as:

"The strongest earthquake in the U.S. or Canada today was an M 3.6 in the island of Hawaii, Hawaii. NEIC reported this earthquake of M 3.6 in Hawaii was felt with intensity II-III in the area(s) of Hawaii in Holualoa, Captain Cook, Kailua Kona, Hilo, Naalehu, Volcano, Honolulu. This appears to be part of a recent seismic series in the area of Mauna Loa, Hawaii and could precurse a future eruption at that volcano, the first in nearly forty years." (November 10, 2022)

and

"The strongest earthquake in the U.S. or Canada today was an M 4.1 in northern Hawaii. NEIC reported it was felt with intensity IV in the northern area of the island of Hawaii in Kamuela, Honokaa, Wailoloa, Paauilo, Kapaau, with lesser shaking in Hawi, Kailua Kona, Laupahoehoe, Ookala, Papaaloa. This follows an M 3.5-3.6 near Mauna Loa yesterday, possibly connected with an upcoming eruption at that volcano." (November 2, 2022)

and

"The strongest earthquake in the U.S. or Canada today was an M 3.6 in the Mauna Loa Volcanic area of southern island of Hawaii. This is part of a recent enhancement of seismicity with this volcano. Some fear this may lead to the first major eruption at this volcano in 40 years." (November 1, 2022)

and

"A series of light to moderate earthquakes occurred near Mauna Loa, Hawaii today. The strongest of these was an M 5.0. NEIC reported it was felt with maximum intensity VI in Hawaii at Pahala; IV in Naalehu, Hawaii National Park, Captain Cook, Volcano, Holualoa, Pahoa, Hilo, Mountain View, Kealakekua.

Aftershocks included an M 3.6 which was felt with intensity II-III in Pahala, Naalehu and Captain Cook. An M 3.9 was felt with intensity II-III in Naalehu, Captain Cook, Volcano, Hilo, Kurtistown, Kailua Kona, Waikoloa. The M 5.0 is the strongest earthquake in the area of Mauna Loa since an M 5.8 on April 17, 1999.

Other earthquakes in the area of Hawaii within about 100 km of this epicenter with M>=5 have recently occurred one year ago on October 10, 2021 and an M 5.3 on April 14, 2019. Forecast 147112 had expected today's activity within about 50 km was likely around October 8. This activity is at the fourth node (90 degrees) from the M 6.6 in Sichuan, China of September 5 and at the fifth node (52 degrees) from the M 7.0 in the Loyalty Islands of September 14, 2022 and may have been enhanced by energy from those sources." (October 15, 2022).

The plume from today's volcanic eruption caused air traffic to be re-routed and evacuation plans were in effect. But the lava (thus far) has not threatened residential areas and is flowing away from populated regions. Up to an inch of ashfall was expected in the first days of this eruption in Hawaii.

The initial earthquake in the volcanic sequence today occurred as an M 2.0 in Hawaii at 22:40 UT (within minutes of local solar noon) and increased in intensity from that point on maximizing near local solar midnight with an M 4.3 and a cascade of minor volcanic tremors after that. This timing suggests tidal stresses were prominent in the seismicity associated with this eruption.

Hawaii is a major factor in global seismicity as it is situated in the middle of the "ring of fire" around the North Pacific Ocean. This eruption will probably

reduce stresses along this belt leading to a reduction in coming days of the strong seismicity in the region of the past month.

The strongest shocks associated with the volcanic eruption of Mauna Loa today were an M 4.3 and an M 4.0. The M 4.2 was reported by NEIC to have been felt with intensity II-III in Hawaii at Captain Cook Hawaii National Park, Hilo, Volcano, Kailua Kona, Mountain View, Pepeekeo, Honokaa, Honomu and Haiku.

NEIC reported the M 4.0 was felt with intensity IV in Kailua Kona and III in Hilo and Captain Cook, Hawaii.

This eruption also coincided with the largest geomagnetic storm of the month of November and may have been affected by stresses associated with that storm as noted in this and the previous issue of this summary as:

"The geomagnetic field saw minor storm conditions today. The AP level was 24. High latitudes saw minor storm conditions with AP 25. Middle latitudes were at active conditions with AP 18. This is the strongest geomagnetic storm since global AP reached 26 on November 3 and is likely to promoted seismicity near the geomagnetic equator and at high latitudes in the next several days. Earthquakes in Vancouver and Solomon hit as this storm was reaching maximum intensity." (November 28, 2022)

The largest shocks associated with the eruption occurred near local solar midnight and were probably enhanced by strong tidal stresses which maximize near this hour. Following is a listing of associated earthquakes of M>=3 a subset of hundreds of volcanic tremors of M>=2. Forecast 148457 had expected today's activity was likely in late November between November 24 and 27, 2022.

The volcanic area of northern Iceland also saw a significant event today. An M 4.0 in this area was the strongest earthquake within about 150 km of this epicenter since an M 4.1 on August 2, 2022. The only event of M>=5 in this

area in the past year was an M 5.0 on February 22, 2022. Today's event occurred within minutes of local solar midnight and may have been promoted by strong tidal stresses which maximize near this hour. Forecast 148610 had expected this activity in this area was likely around November 25. This earthquake like moderate earthquakes today in Bosnia and Missouri is located at the third node (120 degrees) from the M 7.6 in New Guinea of September 10, 2022. Also, like the eruption in Hawaii, this area of Iceland is located near 103 degrees from the M 6.9 in Sumatra of November 18. Like the eruption in Hawaii, this epicenter is also at the fifth node (72 degrees) from the M 6.9 in Panama of October 20 and was likewise also affected by energy from that source.

An earthquake of M 4.5 also hit the region of Chihuahua, Mexico today. This is part of a series in this area which began with moderate earthquakes north in Western Texas earlier this week. The M 4.5 is the strongest within about 200 km of this epicenter since an M 4.6 of October 4, 2013, in turn an aftershock of an M 5.4 on September 21, 2013, the only other such events in the region in the past 35 years. At the time this summary noted in this regard:

The earthquakes in Chihuahua, Mexico follow several days of quiet seismicity after a strong swarm began in the area on September 11, 2013 with an M 4.6. At the time this summary had noted in this regard:

"The earthquake of M 4.5 in Chihuahua, Mexico near Hidalgo del Parral, Mexico was the largest of a series of at least four moderate quakes in that area today with M 4.2, 3.9, 4.5 and 4.4. At M 4.5 this is the strongest earthquake to occur within 200 km of this epicenter in the past 25 years. Earthquakes of M>4 hit on July 29, 2011 (M 4.2) and May 1, 2010 (M 4.3). This is a remote area and there were no initial reports of felt activity. The epicenter is at 101-104 degrees from at least three large recent earthquakes and this may have help trigger this and the activity to the south on the Central East Pacific Rise today."
