Before revision: M w scale Kanamori (1977) defined a magnitude scale (Log W0 = 1.5 Mw + 11.8, where W0 is the minimum strain energy) for great earthquakes using Gutenberg Richter Eq.
After revision: M w scale Hiroo Kanamori defined a magnitude scale (Log W0 = 1.5 Mw + 11.8, where W0 is the minimum strain energy) for great earthquakes using Gutenberg Richter Eq.
