Mercalli intensity scale. The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the ... For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.HAMOON Max Wind Speeds.

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into ...
Mar 22, 2023 · The severity of an earthquake is measured on a Richter scale. It is logarithmic scale that measures the magnitude of an earthquake. The scale ranges from 1 to 10, with each increase in number indicating a tenfold increase in ground motion. For example, an earthquake with a magnitude of 7 is ten times more powerful than an earthquake with a magnitude of 6.
