Turkey's disaster authority and the U.S. Geological Survey say a 5.0 magnitude earthquake has struck Siirt in southeastern Turkey.

The Disaster and Emergency Management Authority, or AFAD, said on Dec. 3 there were no immediate reports of casualties or damage from the quake that hit at a depth of 20 kilometers (12 miles) at 8:45 a.m. (0545 GMT).

Turkey is crisscrossed by fault lines and was hit by two strong tremors this year - one that hit the western port city of Izmir last month, killing 117 people, and another in Elazığ province, killing 41 people.

At least 17,000 people died in a powerful earthquake in northwest Turkey in 1999.

Taal Volcano (taken October 26, 2020).
Five volcanic earthquakes were recorded in Taal Volcano in the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday.

In its 8 a.m. volcano bulletin, Phivolcs said Taal Volcano also emitted steam-laden plumes at the main crater vents.

Weak to moderate degassing activity in Daang Kastila Trail were also recorded in the volcano.

The agency also noted that the northwestern part of the Taal Caldera still has inflation while the southwestern part showed no changes after the Taal eruption.

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:
