Wildfires. Earthquakes. Drought. Severe storms and floods are the most common types of natural disasters reported in the United States. These meteorological events are occasionally preceded by presidential "emergency declarations ...To compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power: 10^ (M1-M2). For example, if the magnitude of one quake is 6 and another is 4, than the difference in magnitudes is 2, so the stronger earthquake shakes 10^2 or 100 times as hard as the milder one.Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10. Richter’s scale was originally for measuring the magnitude of earthquakes from magnitudes 3 to 7, limiting its usefulness.An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the ...The earthquake magnitude scale is used to describe the overall strength, or "magnitude" of an earthquake.
