MODERATE QUAKES IN NORTHERN SPAIN; NORTHERN CHILE
EARTHQUAKE SUMMARY FOR JANUARY 27, 2022
The largest earthquake in the world today was an M 5.5 in northern Chile.
GUC reported this earthquake was felt with intensity V in Arica and Parinacota at Codpa, Cuya, Pocon Chile, San Miguel de Azapa, VI in Arica; in Tarapaca with IV in Alto Hospicio, Camina, Iquique, Mamina, Pozo Almonte, Ujina III in La Tirana, II in Pica, Pisagua, Huara, Chile. NEIC reported this earthquake of M 5.5 in Northern Chile was felt with intensity II-III in the area(s) of Northern Chile in Tarapaca with IV in Arica and Iquique and in Peru at Moquegua, Arequipa and in Cochabamba, Bolivia. This is the strongest earthquake within about 200 km of this epicenter in northern Chile since an M 6.1 on December 6, 2020 more than a year ago. An M 5.5 also hit the area on August 3, 2020. A regional earthquake of M 5.5-5.6 hit the area about 250 km northwest of this on December 7, 2021. This epicenter is near 105 degrees from the strong M 6.8 in the Fox Islands of January 11, 2022 and may have been promoted by energy from that epicenter. Forecast 140743 had expected today's event within about 50 km was likely around January 24. This activity is near 104 degrees from the M 7.2 in Vanuatu and the M 6.8 in the Fox Islands and may have been promoted by energy from those sources.

An earthquake of M 3.9-4.7 occurred today in northern Spain. NEIC reported it was felt with intensity II in Lousmae, Pontevedra and Vigo, Spain. The last earthquake within about 200 km of this epicenter in northern Spain with M>=4.6 was an M 4.8 on June 10, 2006 and an M 5.0 on April 3, 2006. The strongest earthquake in the region in the past 30 years was an M 5.4 on May 21, 1997. Today's activity follows a series of foreshocks in the area which have been followed by this summary. When an M 2.9 occurred on January 18, 2022, this summary noted in this regard:
"A series of light earthquakes also occurred today in northern Spain. These were lightly felt in the epicentral area. The largest of these was an M 2.9. Light earthquakes also occured in the Pyrenees of France. Forecast 140430 had expected this activity within about 100 km was likely around January 20." (January 19-20, 2022)
Today's activity occurred near local solar noon and may have been enhanced by strong tidal stresses.

An earthquake of M 2.5 was felt in the area of Lake Erie, Ohio today. NEIC reported intensity II in Ohio at Eastlake, Euclid, Painesville, Cleveland,
Akron, Wayne, Indiana. The last earthquakes in the Lake Erie area within
about 100 km of this epicenter occurred on January 4 with M 2.8 and July 17, 2021 with M 4.2. When this earthquake occurred in July, 2021 this summary noted:
"As often occurs the significant earthquake off the coast of Northern California was preceded several hours earlier by a significant earthquake in the northeastern U.S. In this case an M 4.2 occurred in Lake Erie, Ohio and was lightly felt in the area. Two earthquakes of equal or larger magnitude have occurred in the Lake Erie area of Ohio in the past 30 years - an M 4.4 on January 26, 2001 and an M 4.5 on September 25, 1998." (July 18, 2021)
Today's event in Ohio of M 2.1-2.5 occurred as a major nor'easter is beginning to progress up the eastern coast of the U.S. It may hit the Boston area with record snows today and on Saturday, January 29, 2022. Such nor'easters are often associated with a strong enhancement of seismicity along the western North American tectonic plate. A precautionary seismic watch is being called by this summary for this region through February 2, 2022. This epicenter is located at 101 degrees from the M 6.9 in Qinghai of January 7, 2022 and may have been promoted by energy from that source. Other activity at this distance from Qinghai today occurred in the Kermadec Islands (M 4.0) and in Baja and Tijuana, Mexico (M 3.7, 2.1).

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.

STRONG QUAKE NORTH OF HUNGA-TONGA
EARTHQUAKE SUMMARY FOR JANUARY 26, 2022
The strongest earthquake in the world today was an M 6.2 that occurred about
150 km north of the site of the volcanic eruption at Hunga-Tonga of January 15, 2022. This event was felt lightly in this epicentral area. A series of moderate earthquakes began in the region four days after the eruption and had continued daily since that time as noted in previous issues of this summary:
"...the first strong series of events near the volcanic eruption of January 14-15 in Tonga occurred today with five moderate earthquakes." (January 21, 2022)
This earthquake is the strongest within about 150 km of this epicenter since an M 6.5 on April 24, 2021 and an M 6.4 on October 1, 2020. Most earthquakes in this area are at intermediate or deep focus so the focal depth of today's event of 4.2 km is the shallowest such event in this region in at least 30 years. It was probably promoted by stress redistribution following the eruption of January 14-15. Forecast 140747 had expected enhanced seismicity within about 50 km of this event in Fiji of M 6.2 today. This activity is near 100 degrees from the M 7.5 in Peru of November 28, 2021 and may have been promoted by energy from that source. Moderate earthquakes in the Rat Islands in the past two days are also at this distance from Peru. It is also at the fifth node (72 degrees) from the M 6.8 in the Fox Islands of January 11, 2022 and at the sixth node (60 degrees) from recent major events in Flores, Indonesia and may have been enhanced by energy from those sources.

The strongest earthquake in the U.S., Canada or vicinity today was an M 4.6 in western Greenland. It was not reported felt in this remote area. This continues a series of similar events of M 4.5 and 4.6 on January 15 and January 19, 2022. The only earthquake of significantly larger magnitude within about 300 km in the past 30 years was an M 5.0 at this epicenter on October 14, 1998. These earlier events occurred near local solar midnight and noon and may have been promoted by high tidal stresses. The same may apply to today's event. Forecast 140718 had expected this activity in the region in late January.

Seismicity in the Kilauea Volcanic zone of Hawaii was active today following an M 4.7 in Maui about 200 km to the north of this occurred yesterday. Today's activity included an M 3.9 and M 3.2 among other smaller events associated with the volcanism on Hawaii. This activity had been expected to occur around January 25. The M 3.9 occurred near local solar midnight and may have been promoted, like the M 4.7 yesterday, by high tidal stresses. Today's increased seismicity in the volcanic zone had been anticipated in this summary in the previous issue as:
"This (the M 4.7) is not part of the current eruption of Kilauea but may bring increased seismicity to the big island of Hawaii and to that eruption. Today's even occurred within minutes of local solar midnight and was probably promoted by high tidal stresses which maximize near this hour." (January 25-26, 2022)
NEIC reported this earthquake of M 3.6-3.9 in Hawaii was felt with intensity II-III in the area(s) of Hawaii at Naalehu, Volcano, Captain Cook, Hilo, Kurtistown, Holualoa, Kailua Kona, Opla;a. Honokaa and Kula.

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.
