  • The data below are the most preferred data available
  • The data below have NOT been reviewed by a scientist.

  • Damaging earthquakes can occur in the future, so remember to: Drop, Cover, and Hold on.
  • More earthquakes than usual (called aftershocks) will continue to occur near the mainshock. The mainshock is the largest earthquake in a sequence (a series of earthquakes related to each other).
  • When there are more earthquakes, the chance of a large earthquake is greater which means that the chance of damage is greater.
  • No one can predict the exact time or place of any earthquake, including aftershocks. Our aftershock forecasts give us an understanding of the chances of having more earthquakes within a given time period in the affected area.
