#volcanoawarenessmonth

#MountStHelens May 18, 1980, 8:32 AM. A colossal landslide. Magma & hot fluids explode, surge outward like a hot hurricane. Column rises, ash falls for miles. Snowpack melts, mudflows converge, lahars move downvalley. A 9-hr eruption. Everything is changed. #VolcanoAwarenessMonth
