The 2190 eruption of Mt Adams was a highly destructive, very unexpectedly violent eruption that began at 1345 PDT on February 18, 2190. It was later ranked as a VEI 7 eruption, and was responsible for extreme ash falls on the surrounding areas around the volcano. In addition, a landslide occurred from a particularly violent explosion on March 7, which caused the volcano to collapse into a caldera. 12 people died, and 176 more were injured, whilst damages from the eruption totaled $34 billion once totaled up. The volcano fell silent on May 13th, falling back into a new period of presumed dormancy once again.
