Name the scale used to measure tornado intensity.

The Enhanced Fujita Scale (EF Scale) is the correct answer because it is specifically designed to measure the intensity of tornadoes based on the damage they cause to buildings and vegetation. This scale categorizes tornadoes from EF0, indicating minimal damage, to EF5, which signifies devastating damage with winds exceeding 200 miles per hour. The EF Scale is widely adopted by meteorologists and emergency management agencies to assess the strength of tornadoes after they occur, allowing for better understanding and response to these natural disasters.

Other scales mentioned serve different purposes. The Richter Scale measures the magnitude of earthquakes, the Saffir-Simpson Scale, assesses hurricane intensity, and the Beaufort Scale describes wind speeds and their effects on the environment. Each of these scales focuses on distinct meteorological phenomena, highlighting why the Enhanced Fujita Scale is specifically applicable to tornadoes.
