Enhanced Fujita Scale
|Scale||Wind speed (mph)||Possible Damage|
|EF 0||65-85||Minor or no damage.
Peels surface off some roofs; some damage to gutters or siding; branches broken off trees; shallow-rooted trees pushed over. Confirmed tornadoes with no reported damage (i.e., those that remain in open fields) are always rated EF0.
|EF 1||86-110||Moderate damage.
Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken.
|EF 2||111-135||Considerable damage.
Roofs torn off well-constructed houses; foundations of frame homes shifted; mobile homes completely destroyed; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground.
|EF 3||136-165||Severe damage.
Entire stories of well-constructed houses destroyed; severe damage to large buildings such as shopping malls; trains overturned; trees debarked; heavy cars lifted off the ground and thrown; structures with weak foundations are badly damaged.
|EF 4||166-200||Extreme damage.
Well-constructed and whole frame houses completely leveled; cars and other large objects thrown and small missiles generated.
|EF 5||Over 200||Total destruction of buildings.
Strong framed, well built houses leveled off foundations and swept away; steel-reinforced concrete structures are critically damaged; tall buildings collapse or have severe structural deformations.
