Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

A Magnitude 6.3 earthquake occurred near east coast of Taiwan.

A Magnitude 6.3 mainshock followed by a M5.1 aftershock struck about 60km east of the coastal town of Hua-lien, Taiwan, at a depth of 24.7 km, USGS reported.

The quake occurred about 40km east of an unnamed volcano [Volcano Number: 0801-03= ; Latitude: 24.00°N,  Longitude: 121.83°E] where according to the Global Volcanism Program:

A submarine eruption observed by the U.S. Navy boat “Southampton” took place on October 29, 1853 in the Philippine Sea offshore from the city of Hualien about 18 km from the eastern coast of Taiwan. Several days later another ship, the “Macedonian,” passed the same location and reported white ash covering its curtains.

Subject to further seismic activity in the area FEWW will publish the probability of eruption at volcano 0801-03.
