Eruption of Mt. St. Helens - Mon, May 18 @ 01:00 (-5d, 12h, 35m)
On this day in 1980 (now 46 years ago), Mount Saint Helens, a beautiful, symmetrical stratovolcano cone often referred to as "the Fuji of the Northwest," erupted explosively after months of signs that it was waking up. The eruption was triggered by a huge landslide, and the mountain blew away its summit and the southern quadrant of its cone. In many areas, for the next couple of days, it was pitch-black from the clouds of volcanic dust. Huge lahars washed down many rivers, and the showpiece of the area, Spirit Lake, was drowned in boiling debris. The eruption was extensively covered by international media. Subsequent smaller eruptions carried ash up into Canada. The sound of the eruption was heard up to 320 kilometres away, including by the Author, as he delivered papers on southern Vancouver Island.
