4 clues

Clues to a volcanic eruption

some clues consist of :
  • seismic disturbances
  • the amount of sulfur dioxide emmisions increase
  • slight swelling in the volcano's slope
  • if there was a recent eruption the seismic activity might set off a near by volcano
if you are in the vacinity of a volcano and you experience some of there signs it would be wise to evacuate the area immediatley.
