The Richter scale (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, 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".Mercalli Intensity Scale. Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale. Developed in 1935 by Charles Richter, this scale uses a seismometer to measure the magnitude of the largest jolt of energy released by an earthquake.

If a second earthquake has 800 times as much energy as the first, find the magnitude of the second quake. Round to the nearest hundredth. The magnitude of the second earthquake was Number.1. Plate Tectonics: Most earthquakes occur along the boundaries of tectonic plates. 2. Seismic Waves: These waves transmit the energy released during an earthquake, causing shaking and ground motion. 3. Magnitude and Intensity: Earthquakes are measured on the Richter scale, which quantifies the energy released.Jun 22, 2023 · The intensity of an earthquake is the strength of the shaking caused by the earthquake. Intensity is measured on the Modified Mercalli Scale. This is a scale that is based on effects observed from the earthquake and to what degree those effects are felt. It ranges on a scale from 1 to 12, one being the lowest effects and 12 being total loss. Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale.
