TABEL SKALA KECEPATAN ANGIN DAN POTENSIAL KERUSAKAN BERDASARKAN SKALA FUJITA


Enhanced Fujita scale

The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes in the United States based on the damage they cause. Below is that scale.
Scale Wind speed Relative frequency Potential damage
mph km/h
EF0 65–85 105–137 53.5% 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.
EF0 damage example
EF1 86–110 138–178 31.6% Moderate damage. Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken.
EF1 damage example
EF2 111–135 179–218 10.7% 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.
EF2 damage example
EF3 136–165 219–266 3.4% 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.
EF3 damage example
EF4 166–200 267–322 0.7% Extreme damage. Well-constructed and whole frame houses completely leveled; cars and other large objects thrown and small missiles generated.
EF4 damage example
EF5 >200 >322 <0.1% Total Destruction. Strong-framed, well-built houses leveled off and foundations swept away; steel-reinforced concrete structures are critically damaged; tall buildings collapse or have severe structural deformations.
EF5 damage example
