Oct 19, 2023 · Fast Fact: Measuring Earthquakes. Earthquakes are measured by special machines called seismometers. Scientists use the numbers from 1 to 10 to say how strong an earthquake is. This number system is called a scale, or a magnitude scale. Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes.

Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 12.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.

The seismic moment is a measure of the total amount of energy that is transformed during an earthquake. Usually only 1-10 percent or less of an earthquake's total energy is released in the form of radiated seismic waves. How much energy is converted / released in an earthquake?

Earthquakes above 6.0 typically damage buildings. Earthquakes that measure 8.0 or higher are severe.The magnitude scale is really measuring the physical size of the earthquake, not the STRENGTH (energy) of the quakes. So, a magnitude 8.7 is 794 times bigger than a 5.8 quake as measured on seismograms, but the 8.7 quake is about 23,000 times STRONGER than the 5.8! Since it is really the energy or strength that knocks down buildings, this is ...

See a presentation to understand liquefaction. See the catastrophic aftermath of the San Francisco earthquake of 1906. The Richter scale and how it measures earthquake magnitude. The Richter scale calculates an earthquake's magnitude (size) from the amplitude of the earthquake's largest seismic wave recorded by a seismograph.

The first earthquake magnitude scale was invented by Charles Richter for southern California in 1935. Unlike seismic intensity, which measures the strength of shaking and varies according to distance from the quake and other factors, the magnitude is intended to measure the intrinsic size of an earthquake.
