Intensity of the earthquake

The intensity and death toll depend on several factors (earthquake depth, epicenter location, and population density, to name a few) and can vary widely. Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. On the other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average.

The following is an excerpt from Intensity Distribution and Isoseismal Maps for the Northridge, California, Earthquake of January 17,1994. The intensity of an earthquake at a location is a number that characterizes the severity of ground shaking at that location by considering the effects ofthe shaking on people, on manmade structures, and on ... Earthquake magnitude, energy release, and shaking intensity are all related measurements of an earthquake that are often confused with one another. Their dependencies and relationships can be complicated, and even one of these concepts alone can be confusing. Here we'll look at each of these, as well as their interconnectedness and dependencies.

An earthquake has several intensity values, because the shaking and the damages can vary from place to place depending on the distance from the epicenter. The intensity is calculated using human observations and reports of felt shaking and damage.

Magnitude is proportional to the energy released by an earthquake at the focus. It is calculated from earthquakes recorded by an instrument called seismograph. It is represented by Arabic Numbers (e.g. 4.8, 9.0).
