45 years ago, May 18, 1980: the big eruption of Mt St Helens. It started with the biggest landslide in recorded history as the northeast side of the mountain slid away. That uncorked the gas-pressurized magma inside the mountain that exploded without the weight holding it down. An 8 hour eruption killed 57, flattened forests and sent mudflows downstream. Volcanologists learned a lot from it. USGS article about the eruption: https://www.usgs.gov/volcanoes/mount-st.-helens/science/1980-cataclysmic-eruption #MSH45 #volcano #geology #PNW #history #TDIH
