The effects of an earthquake on people and buildings.
Mercalli and Richter scales
Mercalli and Richter scales
The Modified Mercalli Intensity scale is used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the natural environment rather than the seismic energy. It provides a qualitative assessment of the shaking and damage caused by an earthquake at a specific location.
PAGASA uses the Modified Mercalli Intensity (MMI) scale to measure the intensity of an earthquake in the Philippines. This scale assesses the effects of an earthquake on people, structures, and the environment rather than measuring the actual energy released by the earthquake.
The Mercalli Intensity Scale is a measure of earthquake intensity experienced at a given location. The Kobe earthquake in 1995 had intensities reaching up to VIII (8) on the Mercalli Intensity Scale in the heavily affected areas around Kobe.

False. The three major scales used to measure earthquakes are the Mercalli Intensity Scale, the Richter Scale, and the Moment Magnitude Scale. The Mercalli Scale measures the intensity of shaking and its effects on people and structures, while the Richter and Moment Magnitude Scales quantify the energy released by an earthquake.
This is known as intensity. There are a number of intensity scales including the Modified Mercalli scale which is commonly used in the US and the Macroseismic scale as used in Europe.
Intensity is commonly measured using scales such as the Richter scale for earthquakes, the Beaufort scale for wind speed, the decibel scale for sound, and the Mercalli scale for earthquake intensity as felt by humans.
The 2011 earthquake in Tohoku, Japan measured at a Mercalli intensity of VII (Very strong). The Earthquake had a magnitude of 9.0 and led to widespread damage and casualties.
