Scale used to measure the intensity of tornadoes based on the damage caused
A
Enhanced Fujita Scale
B
Saffir-Simposon Scale
C
Richter Scale
D
Modified Meralli Scale
E
Moment Magnitude Scale
Explanation: 

Detailed explanation-1: -The Enhanced Fujita scale rates the intensity of tornadoes based on wind speed and damage caused. An EF5 tornado is estimated to have wind speeds greater than miles per hour.

Detailed explanation-2: -The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a ‘rating’ based on estimated wind speeds and related damage.

Detailed explanation-3: -The Fujita (F) Scale was originally developed by Dr. Tetsuya Theodore Fujita to estimate tornado wind speeds based on damage left behind by a tornado. An Enhanced Fujita (EF) Scale, developed by a forum of nationally renowned meteorologists and wind engineers, makes improvements to the original F scale.

Detailed explanation-4: -The F-scale is based on the amount of destruction a tornado causes, whereas the EF-scale relies more on wind-speed to determine a tornado TMs rating. Let TMs take for example, the three little pigs: A tornado comes along and huffs and puffs at the houses of straw, sticks and bricks.
