Symbole | M<sub>e</sub> |
Description | These magnitudes are computed from the radiated energy using the method described in Choy and Boatwright (1995). The energy radiated by an earthquake is estimated from the energy spectral density of the broadband P waves (Boatwright and Choy, 1986). The Me can complement moment magnitudes (Mw) in describing the size of an earthquake. Me, being derived from velocity power spectra, is a measure of the amount of damage that could be caused. Mw, being derived from low-frequency asymptote of displacement spectra, is more physically related to the final static displacement of an earthquake. |
