The pioneering seismologist Charles Richter started in the 1930s by simplifying everything he could think of. He chose one standard instrument, a Wood-Anderson seismograph, used only nearby earthquakes in Southern California, and took only one piece of data—the distance A in millimeters that the seismograph needle moved.The intensity of an earthquake is measured by the amount of ground motion as measured on a seismometer. The Richter scale is not designed so that you must ...The Modified Mercalli scale measures the earthquake’s effect on people, property and ground damage. Roman numerals are used to rate the intensity and damage. An earthquake may have a different intensity rating at different locations. Damage is usually lessened with distance from the earthquake’s epicenter.The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes.Anti-Hero Taylor Swift caused a small earthquake in Seattle last weekend Seattle fans at Taylor Swift's Eras Tour danced so hard they registered a 2.3 magnitude earthquake on the Richter scaleEarthquakes 8.0 or higher can destroy areas near the epicenter.
