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

Massive Eruption at Soufriere Hills Volcano

Posted by feww on March 25, 2010

The Soufriere Hills volcano in Montserrat ejects a large plume of ash up to 12km into the air

Passengers on a 737 jet flying over the Caribbean had a close-up look at a massive volcanic eruption which ejected a plume of ash and smoke higher than the flight altitude. Early reports indicate that a partial collapse of the volcano’s lava dome may have caused the mushroom cloud.  (Image: Mary Jo Penkala/Solent). Image may be subject to copyright.

A massive eruption of Montserrat’s Soufrière Hills Volcano triggered by a collapse of Soufrière Hills’ summit lava dome  covered large portions of the island in debris on February 11, 2010. Pyroclastic flows raced down the northern flank of the volcano, leveling trees and destroying buildings in the village of Harris, already abandoned after Soufrière Hills activity in 1995. The Montserrat Volcano Observatory reported that some flows, about 15 meters (49 feet) thick, reached the sea at Trant’s Bay, extending the island’s coastline up to 650 meters (2,100 feet). These false-color satellite images show the southern half of Montserrat before and after the dome collapse. The top image was taken on February 21, 2010, 10 days after the event. The bottom image shows the same area on March 17, 2007. Red areas are vegetated, clouds are white, blue/black areas are ocean water, and gray areas are covered by flow deposits. Fresh deposits are lighter than older deposits. On February 21, the drainages leading down from Soufrière Hills, including the White River Valley, the Tar River Valley, and the Belham River Valley, were filled with fresh debris. Pyroclastic flows reached the sea through Aymers Ghaut on January 18, 2010, and flows entered the sea near Plymouth on February 5, 2010, Montserrat Volcano Observatory said.
