The 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.

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…
