The rupture displacement in an earthquake is typically about 1/20,000 of the rupture length. For example, a 1 km long rupture from an Mw 4.0 event has a displacement of about 1km/20,000, or 0.05 metres. A magnitude Mw 8.0 earthquake with a rupture length of 100 km may give a displacement of a few metres.
An earthquake is the sudden movement of Earth’s crust at a fault line. This photograph shows the San Andreas Fault, a 750-mile-long fault in California. Credit: Public Domain. The location where an earthquake begins is called the epicenter. An earthquake’s most intense shaking is often felt near the epicenter.It is based on the amplitude of the earthquake waves recorded on instruments, which have a common calibration. Magnitude is thus represented by a single, instrumentally determined value. The Richter Magnitude Scale. Seismic waves are the vibrations from earthquakes that travel through Earth; they are recorded on instruments …The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.Kōbe earthquake of 1995, also called Great Hanshin earthquake, Japanese in full Hanshin-Awaji Daishinsai (“Great Hanshin-Awaji Earthquake Disaster”), (Jan. 17, 1995) large-scale earthquake in the Ōsaka-Kōbe (Hanshin) metropolitan area of western Japan that was among the strongest, deadliest, and costliest to ever strike that country.. …The Richter scale , 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".
