Earthquake severity scale.
The moment magnitude scale (MMS; denoted explicitly with M w or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment.It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.Similar to the local magnitude/Richter scale (M L ) defined …
An earthquake with a magnitude of 6.7 struck the southern California city of Northridge in 1994. The quake killed 57 people, injured more than 9,000, and displaced over 20,000. It caused an estimated $20 billion in property losses and infrastructure damages. It is considered the costliest earthquake in U.S. history.27 avr. 2023 ...
