The modified mercalli intensity scale is used to measure the intensity of an earthquake and is in part derived from the damage done to building and other structures. Edit Share to:
Seismic waves that travel along the outer layer of Earth, show the highest amplitudes on a seismogram, and are the most destructive. Smaller earthquakes that follow the main earthquake. This magnitude scale is a measure of the energy released and is determined from the amplitude of the largest seismic wave. It does NOT directly measure the extent of building damage.
