v. t. e. The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". [3]The magnitude of an earthquake is a number that characterizes the relative size or amount of elastic energy released by such an event (see “Earthquakes, Energy”).It is usually based on measurement of the maximum ground motion recorded by a seismograph (sometimes for a particular wave type and frequency) and corrected for the …

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary …The study of earthquakes, called seismology, began to take off with the development of instruments that can detect earthquakes; this instrument, called a seismograph, can measure the slightest of Earth’s vibrations (Figure 13.5). A typical seismograph consists of a mass suspended on a string from a frame that moves as the Earth’s surface moves.It measures the energy released during an earthquake by analyzing the amplitude of seismic waves recorded on seismographs. The Richter scale is logarithmic, meaning that each whole number increase on the scale corresponds to a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released.The MyShake app -- developed by the UC Berkeley Seismology Lab, sponsored by the California Governor’s Office of Emergency Services -- was the first app powered by ShakeAlert® to provide statewide earthquake early warning alerts in California. The app is one of the delivery modes of the California Earthquake Early Warning System.
