F-Scale:

A measurement scale used to categorize and quantify the intensity of tornadoes, known as the Fujita Scale.

EF-Scale:

The Enhanced Fujita Scale, an update to the original F-Scale that takes into account additional damage indicators.

Tornado Intensity Levels:

Categories used to classify tornadoes based on estimated wind speeds and associated damages:

EF0 – Weak:

Wind Speeds: 65-85 mph (105-137 km/h)
Light damage: Damages trees and pushes over shallow-rooted plants.

EF1 – Weak:

Wind Speeds: 86-110 mph (138-177 km/h)
Moderate damage: Roofs are partially removed, mobile homes overturned, and cars pushed off roads.

EF2 – Strong:

Wind Speeds: 111-135 mph (178-217 km/h)
Considerable damage: Roofs torn off homes, large trees uprooted, and mobile homes completely destroyed.

EF3 – Strong:

Wind Speeds: 136-165 mph (218-266 km/h)
Severe damage: Well-constructed houses suffer significant damage, trains overturned, and heavy cars lifted off the ground.

EF4 – Violent:

Wind Speeds: 166-200 mph (267-322 km/h)
Devastating damage: Strong-framed houses leveled, cars thrown significant distances, and trees debarked.

EF5 – Violent:

Wind Speeds: Over 200 mph (Over 322 km/h)
Incredible damage: Homes swept away, severe deformation of large buildings, and cars thrown like projectiles.
