The Fujita Tornado Scale, usually referred to as the F-Scale, classifies tornadoes based on the resulting damage The Fujita scale (F-Scale; / f u ˈ dʒ iː t ə /), or Fujita-Pearson scale (FPP 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 or aerial damage survey, or both; and depending on the circumstances, ground. Tornadoes are rated by their intensity and the damaged they cause to vegetation and human created structures
