Next week marks the 100 year anniversary of the Novarupta Volcano eruption on the Alaskan Peninsula — the most forceful volcano eruption of the 20th century. How big was it? According to NASA:

  • It expelled three cubic MILES of magma and ash. 
  • When all of that stuff landed it covered an area of 3,000 square miles.
  • All that magma and ash on the ground was a foot deep.
