Jul 1, 2021 · Detailed Description. Earthquake Intensity - Modified Mercalli Intensity (MMI) Scale. The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place. The lower numbers ... The MM scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli 's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves.Earthquakes can be classified into 4 different types.

Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.An earthquake refers to the shaking of the earth’s surface caused by a sudden release of energy within the earth’s crust. This release of energy generates seismic waves, commonly known as S waves. The intensity and characteristics of an earthquake are determined by the seismic activities occurring in a specific region. The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.Whereas the magnitude of an earthquake is one value that describes the size, there are many intensity values for each earthquake that are distributed across the geographic area around the earthquake epicenter. The intensity is the measure of shaking at each location, and this varies from place to place, depending mostly on the distance from the ...

Magnitude and intensity are both measurements that are done when an earthquake occurs. Magnitude is a measurement of the size of the earthquake as measured by waves or fault displacement. Intensity is a measurement of how much shaking has occurred as measured by levels of observable destruction of man-made and natural objects.

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake.
