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

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.

Dozens of parrots found dead on mobile phone mast in the Philippines

dead parrots
A worker was shocked after finding dozens of dead birds on top of a mobile phone mast in the Philippines.

Rigger technician Edward Tapia climbed the tower in Surigao del Sur province for a maintenance check on November 21.

Edward climbed up the 130ft-tall structure but when he reached the top, there were dozens of birds that had died mysteriously.

The blue-naped parrots, a species found throughout the Philippines, were in different stages of decomposition suggesting that they did not all die at the same time. There were several other types of dead alongside them.

Edward found the creatures stacked up in the platform corner beside a machine installed on the tower, which transmits 3G and 4G network signals.

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:
