A Method to Determine Moment Magnitudes of Large Earthquakes Based on the Long‐Period Coda

Abstract We present a novel and robust method for estimating moment magnitudes (Mw) of large earthquakes with long‐period and long‐lasting coda energy. Fitting the energy with a simple decay model, we derive a straightforward relationship between the coda energy and the Mw. Tests with both real and...
