The Intensity Prediction Equation (IPE) is an estimate of intensity for a given earthquake magnitude and distance. Earthquakes in different regions of the world tend to create different levels of shaking for many reasons, such as the mechanism of the earthquake, the nature of the geological environment, and the quality of infrastructure. 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.

As, to find the ...Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.8.9: Magnitude vs. Intensity. Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.

Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre. We can, therefore talk about a magnitude 5.4 ML event with intensity of 6 EMS in the epicentral ... It depends on other variables, such as the distance from the earthquake, what type of soil you are on, building construction, etc. That being said, damage does not usually occur until the earthquake magnitude reaches somewhere above 4 or 5.
