today in 1980, at 8:32am, an earthquake triggers what became the eruption of Mt. St. Helens. the quake from inside the mountain not only caused the north face of it to slide away, but it also sent molten, high pressure gas, rock and ash into the air. several glaciers melted away causing fast flowing lahars (volcanic mudslides). hundreds of acres of forest were reduced to nothing. approxamately 57 people died directly. below is the before during and after the eruption.
