The Fujita scale (F-Scale), or Fujita-Pearson scale, is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists (and engineers) after a ground and/or aerial damage survey; and depending on the circumstances, ground-swirl patterns (cycloidal marks), radar tracking, eyewitness testimonies, media reports and damage imagery.
Tornado speed and damage
F0: 40–72 MPH (64–116 km/h) Light damage to roofs, sidings, and tree branches.
F1: 73–112 mph (117–180km/h) Roofs severely stripped, mobile homes overturned, exterior home damage, vehicles overturned.
F2: 113–157 mph (181–253 km/h) Roofs torn off, mobile homes demolished, large trees snapped or uprooted, small vehicles lifted.
F3: 158–206 mph (254–332 km/h) Entire stories of homes and buildings destroyed, all trees uprooted or lofted, trains overturned, large vehicles (ie. tractors, buses, etc.) blown short distances.
F4: 207–260 mph (333–418 km/h) Homes are completely destroyed and occasionally leveled or swept away, cars thrown around, trees debarked.
F5: 261–318 mph (419–512 km/h): Destruction of all infrastructure, ground scouring observed.
