Earthquake intensity scales describe the severity of an earthquake’s effects on the Earth's surface, humans, and buildings at different locations in the area of the epicenter. There can be multiple intensity measurements. The Modified Mercalli Scale measures the amount of shaking at a particular location.
Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.
Here's a look at how earthquakes are measured and what the magnitude and intensity scales mean. The earthquake magnitude communicates its energy level, and the intensity communicates...
Apr 24, 2024 · To determine the intensity of an earthquake, reports are collected about what people felt and how much damage was done. The reports are then used to assign intensity ratings to regions where the earthquake was felt.

The Richter scale is logarithmic, with each step up the scale marking a tenfold increase in quake strength—a 4.0 quake on the Richter scale, for instance, releases 10 times the energy of a 3.0 earthquake.
Apr 24, 2024 · There are two main ways to measure earthquakes. The first of these is an estimate of the energy released, and the value is referred to as magnitude. This is the number that is typically used by the press when a big earthquake happens. It is often referred to as “Richter magnitude,” but that is a misnomer, and it should be just “magnitude.”
12.2 Seismic Waves and Measuring Earthquakes. The shaking from an earthquake travels away from the rupture in the form of seismic waves. Seismic waves are measured to determine the location of the earthquake, and to estimate the amount of energy released by the earthquake (its magnitude ).
