What damage does the Richter scale cause? – Sage-Answers
WebWhile the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake. … WebThe Richter scale is a numerical scale used to describe an earthquake's magnitude Each whole number increase on the Richter scale corresponds to a 32-fold increase in seismic energy The moment magnitude scale takes into account the size of an earthquake's fault rupture The time an earthquake occurred can be estimated from the seismic wave size opentable amelia island
What is the Richter Scale? Socratic
Web30 jul. 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. WebThe magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML). Web2 okt. 2024 · mb uses relatively short seismic waves with a 1-second period, so to it every quake source that is larger than a few wavelengths looks the same. That corresponds to a magnitude of about 6.5. Ms uses 20-second waves and can handle larger sources, but it too saturates around magnitude 8. ipcc group 2 paper
