Webb5 jan. 2024 · The Richter magnitude is based on the wave amplitude recorded by seismographs. Charles Richter developed the logarithmic scale in 1935 to compare local earthquakes – the ones in southern California with an epicenter of up to 370 miles (600 km) from the seismograph. WebbEarthquakes Living Lab: Finding Epicenters and Measuring Magnitudes Activity—Worksheet 4 12. What is the “magnitude” of an earthquake? Describe it. The magnitude of an earthquake is an estimate of the total amount of energy released during fault rupture. Since the 1930s, earthquakes have been measured using the Richter …
