See all on Wikipediahttps://en.wikipedia.org/wiki/Moment_magnitude_scaleThe moment magnitude scale (MMS; denoted explicitly with Mw 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.

The moment magnitude scale is a way to measure the power of earthquakes. The higher the number, the bigger the earthquake. It is the energy of the earthquake at the moment it happens. Like the similar and older Richter scale, it is logarithmic, with a base of ten. Scale Number.

Skala magnitudo momen (Bahasa Inggris: Moment magnitude scale, sering disingkat Mw atau Mw atau umumnya hanya M untuk magnitudo) adalah ukuran dari besarnya gempa bumi ("ukuran" atau kekuatan) berdasarkan pada momen seismik. Skala ini diperkenalkan pada tahun 1979 oleh Tom Hanks dan Hiroo Kanamori sebagai pengganti skala Richter dan digunakan pada bidang ilmu seismologis untuk membandingkan energi yang dilepas oleh sebuah gempa bumi. Kekuatan mo…

1960年代、ローカル・マグニチュードおよび表面波マグニチュードが地震のエネルギー量を表すマグニチュードの計測法として使われていた。しかし、1,000キロメートルを越えて影響を発生させるような巨大地震の規模を計測するには不適切だった。例えば、1957年のアリューシャン地震や1960年のチリ地震は1,000キロメ…- Estimated Reading Time: 8 mins

The Richter scale – also called the Richter magnitude scale and Richter's magnitude 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". This was later revised and renamed the local magnitude scale, denoted as ML or M L . [citation needed]

From Wikipedia, the free encyclopedia The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake ( Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale.
