IN PHOTOS: A Look at the Devastation Caused by the Volcanic Eruption in St Vincent

La Soufriere volcano fired an enormous amount of ash and hot gas early Monday in the biggest explosive eruption yet since volcanic activity began on the eastern Caribbean island of St. Vincent late last week, with officials worried about the lives of those who have refused to evacuate.

Experts called it a “huge explosion” that generated pyroclastic flows down the volcano’s south and southwest flanks.

“It’s destroying everything in its path,” Erouscilla Joseph, director of the University of the West Indies’ Seismic Research Center, told The Associated Press. “Anybody who would have not heeded the evacuation, they need to get out immediately.”
