The earthquake was reported near a sparsely populated area of the Aleutian Islands, a seismically active area.

A strong earthquake with a preliminary magnitude of 6.4 struck off the coast of a remote area of southern Alaska on Tuesday, but there were no warnings of a tsunami that could threaten the region's sparsely populated string of islands.

The earthquake was reported just after 7 a.m. local time, about 24 miles southeast of Nikolski, a census-designated area of the Aleutian Islands that had a population of 18 people in 2010, according to the U.S. Geological Survey.

Giant 'earthquake fish' caught after 2 quakes strike eastern Taiwan

oarfish
Taiwanese fishermen on Friday (Nov. 6) caught a massive oarfish (Regalecus glesne) nearly 5 meters in length off the coast of eastern Taiwan the same day two earthquakes struck the area.

The oarfish was 490 centimeters long and weighed about 45 kilograms. It was caught off the coast of Dong'ao in Yilan County.

The owner of Fumei Huo Seafood Restaurant (富美活海鮮餐廳) purchased the fish for NT$16,000 (US$560). Chen Kuo-pin (陳國濱) was cited by Liberty Times as saying that it was the longest "earthquake fish" (地震魚) he had ever seen.

Very deep M6.3 earthquake hits Primor'ye, Russia

A very deep magnitude 6.0 earthquake was reported in the morning near Sovetskaya Gavan', Russia.

According to the German Research Centre for Geosciences (GFZ), the quake hit on Tuesday 1 December 2020 at 7.54 am local time at a great depth of 585 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms.

The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.

Our monitoring service identified a second report from the United States Geological Survey (USGS) which listed the quake at magnitude 6.4. Other agencies reporting the same quake include Geoscience Australia (GeoAu) at magnitude 6.4, Italy's National Institute of Geophysics and Volcanology (INGV) at magnitude 6.3, and European-Mediterranean Seismological Centre (EMSC) at magnitude 6.0.

Comment: On Nov. 29th at 1311UT Earth-orbiting satellites detected the biggest solar flare in more than 3 years.

Apart from this very deep Russian earthquake, other seismic and volcanic activity around this time include:

There was a light but noticeable earthquake in the Swabian Alb early Tuesday morning, December 1st, 2020.

Epicenter near Burladingen

The center of the quake with a magnitude of 3.7 was west of Burladingen in the Zollernalb district , as reported by the Southwest earthquake service . The tremors at 0.25 a.m. were believed to have been felt within a radius of 30 kilometers.

No major damage or injuries

The situation center of the Ministry of the Interior in Baden-Württemberg reported several worried calls from the region. A crack in a street was also reported. According to initial findings, there was no major damage or even injuries. There are always minor tremors in the area. The Swiss earthquake service THZ Zurich even reported a strength of 4.1.

At 02:59 local time, the earthquake service reported a weaker earthquake near Albstadt with a strength of 1.8.

Very shallow magnitude 3.1 quake hits 40 km south of Tarbes, France

3.1 quake 28 Nov 11:10 am (GMT +1)

3.1 quake 28 Nov 11:10 am (GMT +1)
Just 14 minutes ago, a 3.1-magnitude earthquake struck near Sers, France. The tremor was recorded in the morning on Saturday 28 November 2020 at 11.10 am local time, at a very shallow depth of 2 km below the surface.

The event was filed by the European-Mediterranean Seismological Centre (EMSC), the first seismological agency to report it.

Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.

Weak shaking might have been felt in Sers (pop. 100) located 10 km from the epicenter, Sers (pop. 100) 10 km away, Betpouey (pop. 100) 10 km away, Aragnouet (pop. 300) 11 km away, and Viella (pop. 100) 12 km away.

Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Bagnères-de-Bigorre (pop. 9,000) located 21 km from the epicenter, Lourdes (pop. 15,800) 29 km away, and Tarbes (pop. 52,100) 40 km away.

A 6.2-magnitude earthquake rocked the Chilean coast, the US Geological Survey has reported. It struck at a depth of 20 kilometers (12 miles).

The jolt occurred late Saturday 157.4 km (97.8 miles) to the southeast of Talca, a city of around 200,000 people south of the capital, Santiago.

There has been no tsunami alert issued as a result of the quake.

Around 10 million people might have felt the quake, according to the European-Mediterranean Seismological Centre.

However, it is not expected to cause casualties or major material damage.
