Earthquake Magnitude and Intensity Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake and is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.
Intensity is determined from effects on people, human structures, and the natural environment.
The effect of an earthquake on the Earth's surface is called the intensity. The following table gives intensities that are typically observed at locations near the epicenter of earthquakes of different magnitudes. More information is available through through the National Earthquake Information Center . Magnitude Intensity Description 1.0 - 3.0 I I . Not felt except by a very few under especially favorable conditions.
