What the magnitude means

  • Under 2.5Usually not felt. Recorded by seismographs. Millions happen each year.
  • 2.5 to 3.9Often felt, little damage. Feels like a passing truck. Hanging objects may swing.
  • 4.0 to 4.9Light. Noticeable shaking indoors, rattling dishes. Damage is rare.
  • 5.0 to 5.9Moderate. Can damage poorly built structures near the epicenter.
  • 6.0 to 6.9Strong. Can be destructive in populated areas up to about 100 miles across.
  • 7.0 and upMajor to great. Serious damage over large areas. A few happen worldwide each year.

Each whole number up the scale means about 32 times more energy released. Shaking at your location also depends on depth, distance and local soil.
