Fire Earth

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

New activity/unrest:

VoW: Curacoa

A submarine volcano south of Curacoa Reef at the northern end of the Tofua volcanic arc was first observed in eruption in 1973. Explosive eruptions, which produced large rafts of dacitic pumice covering an area of more than 100 sq km, were observed from the island of Tafahi, 27 km to the SSW. The eruption site was located about 6.5 km SW of Curacoa Reef. Multiple submarine vents are apparently located in this area; a second eruption was reported in 1979 from a location 13 km north of Tafahi.

FEWW Forecast: FEWW earth model suggests Curacoa may explode spectacularly in one or more episodes this year. [Photos, or eye-witness accounts of any activity will get an honorable mention on the blog.]
