Which scale is used to determine the severity of tornadoes?

The Enhanced Fujita scale is specifically designed to assess the intensity of tornadoes based on the damage they cause to buildings, vegetation, and other structures. This scale categorizes tornadoes into different levels, ranging from EF0, which signifies minimal damage, to EF5, which indicates incredible destruction. Each level is associated with estimated wind speeds and the type of damage expected, allowing meteorologists and researchers to classify tornadoes accurately and communicate their severity effectively.

In contrast, the Richter scale is utilized for measuring the magnitude of earthquakes, the Moment magnitude scale also pertains to quantifying earthquake size, and the Beaufort scale is used for measuring wind speed based on observable effects on the environment. Thus, the Enhanced Fujita scale is the only one that focuses specifically on tornadoes, making it the correct choice for determining their severity.
