This 8 minute video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different places. Magnitudes are based on a logarithmic scale (base 10). What ...

Magnitude is a measurement of the strength of an earthquake. Officially it's called the moment magnitude scale. It's a logarithmic scale, meaning each number is 10 times as strong as the one ...

A magnitude 4.5 earthquake has rattled southern Texas in the vicinity of San Antonio, the U.S. Geological Survey (USGS) ...

On a logarithmic scale, a magnitude 7 earthquake is 10 times more intense than a magnitude 6 and 100 times more intense than ...

Friday's earthquake in Paramus and the one on April 5, 2024, in Tewksbury differ in three key ways: magnitude, location and depth. The factors play a role in who feels an earthquake, how intense it is ...

Earthquakes in Maine, while fairly common, are usually small and do little or no damage. According to the Maine Geological ...

Earthquake magnitudes are measured on a logarithmic scale, meaning each whole number increase represents a tenfold increase in power of the seismic waves, resulting in approximately 31.6 times ...

Magnitude. The strength of an earthquake is based on the logarithmic Richter scale. April 2024's magnitude 4.8 earthquake was 251 times bigger than Friday's magnitude 2.4 earthquake, which is ...
