How are earthquake magnitudes measured

Web30 de jul. de 2024 · The Richter scale is a numeric measure of the magnitude of an earthquake. Beno Gutenberg and Charles F. Richter, both of whom were American seismologists in the year 1935, created it. The magnitude of an earthquake is measured by determining the height of the biggest seismic wave shown on a scale by a seismograph. Web22 de set. de 2024 · Scientists no longer rely on the the Richter scale to measure an earthquake's power. Here's how earthquakes are measured, and why a 7.1 quake is worse than you might imagine.
