The awakening of Mount St. Helens in early 1980 started with a few deep earthquakes below the mountain, and soon grew into signs of volcanic life when cracks in the summit snow appeared and a steam vent blew open a small fissure. More concerns arose when the north side began to bulge at a rate of 5 feet a day. On May 18, 1980, the largest landslide in recorded history was unleashed as one side of the mountain gave way and a massive 9 hour eruption created an ash cloud that would soon eclipse cities to the east in the middle of the day.
