The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]
2.5 to 5.4: Minor or no damage. 5.5 to 6.0: Slight damage to buildings. 6.1 to 6.9: Serious damage. 7.0 to 7.9: Major earthquake. Serious damage. 8.0 or greater: Massive damage, can destroy ...
Strong earthquakes can lead to damage, tsunami warnings and more. People can also be injured or killed by damage caused by a quake. Here's what to know about earthquake activity and what causes ...
For shallow earthquakes – less than roughly 60 km deep – the surface waves are stronger, and may last several minutes; these carry most of the energy of the quake, and cause the most severe damage. An earthquake radiates energy in the form of different kinds of seismic waves, whose characteristics reflect the nature of both the rupture and ...
Where an earthquake is not recorded on seismographs an isoseismal map showing the intensities felt at different areas can be used to estimate the location and magnitude of the quake. [1] Such maps are also useful for estimating the shaking intensity, and thereby the likely level of damage, to be expected from a future earthquake of similar ...

Most earthquake clusters consist of small tremors that cause little to no damage, but there is a theory that earthquakes can recur in a regular pattern. [33] Earthquake clustering has been observed, for example, in Parkfield, California where a long-term research study is being conducted around the Parkfield earthquake cluster.
In general, an earthquake must be at least a magnitude 5 to cause damage, if it's a relatively shallow event, Jones said. "It is a very good reminder to people that we live in earthquake country.
