Less than Generally not felt, but recorded.
Often felt, but rarely causes damage.
Under At most slight damage to well-designed buildings.
Can be destructive in areas up to about kilometers across.
Major earthquake. Can cause serious damage over larger areas.
8 or greater Great earthquake. Can cause serious damage in areas several hundred kilometers across.
