Radiated energy evolution during seismic sequences [PDF]
Physics of the Earth and Planetary Interiors, 2012 Abstract In this paper, I propose a new equation describing the evolution of seismic sequences, based on radiated energy. The evolution of radiated energy in time is described as function of the p and c parameters of the Modified Omori Law and of the energy radiated within a short time following the mainshock.

Effect of directivity on estimates of radiated seismic energy [PDF]
Journal of Geophysical Research: Solid Earth, 2004 To accurately estimate the seismic energy radiated in an earthquake, it is important to use appropriate corrections for path and source effects. Using slip models obtained by inversion of seismic data, we examine the effect of directivity on estimates of radiated energy and develop a method to correct for this source effect.

An electrochemical hypothesis of earthquakes exploring a theoretical link between radiated seismic energy and Pourbaix potential [PDF]
Scientific ReportsEarthquakes are measured using well-defined seismic parameters such as seismic moment ( $$M_o$$ ), moment magnitude ( $$M_w$$ ), and released elastic energy (E).

Global patterns of radiated seismic energy and apparent stress [PDF]
Journal of Geophysical Research: Solid Earth, 1995 Radiated energies from shallow earthquakes with magnitudes ≥5.8 that occurred between 1986 and 1991 are used to examine global patterns of energy release and apparent stress. In contrast to traditional methods which have relied upon empirical formulas, these energies are computed through direct spectral analysis of broadband seismic waveforms. Velocity‐

Discrepancy between local and moment magnitudes attributed to radiated seismic energy [PDF]
Earth, Planets and SpaceWe investigated the factors contributing to variations in local magnitude (M L ) among earthquakes of comparable moment magnitude (M w ). Specifically, we examined how radiated energy accounts for the difference between M w and M jma (∆M = M w − M jma),

Radiated seismic energy from the 2021 ML 5.8 and ML 6.2 Shoufeng (Hualien), Taiwan, earthquakes and their aftershocks [PDF]
Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key points logEs is proportional to 2.0ML for the Shoufeng earthquake sequence in Taiwan. A crossover magnitude detected at ML = 4.0 divides the MW–ML relation into two parts. For ML > 4.0, logM0 ∝ 0.67ML and MW ∝ ML; for ML

Radiated seismic energy from coda measurements and no scaling in apparent stress with seismic moment
Journal of Geophysical Research: Solid Earth, 2010 The seismic coda consists of scattered waves that leave the earthquake source in a variety of directions. The averaging of source radiation that results leads to stable ground motion spectra that we use as the basis for a robust measurement of radiated wave energy.

Radiated seismic energy based on dynamic rupture models of faulting [PDF]
Journal of Geophysical Research: Solid Earth, 2006 By modeling spontaneous ruptures, we study the mechanism dependence of radiated seismic energy from three hypothetical crustal events, 30° dipping reverse fault, 60° dipping normal fault, and a vertical strike‐slip fault, and the 1994 blind‐thrust Northridge earthquake.

Terrestrial, Atmospheric and Oceanic Sciences, 2012 Through a proposed multiple-event analysis of teleseismic P-waves, this study investigated the radiated seismic energy and rupture process of the 2010 JiaSian earthquake. Results showed that the earthquake comprised at least two sub-events. The first sub-

An apparent mechanism dependence of radiated seismic energy [PDF]
Journal of Geophysical Research: Solid Earth, 2001 We develop an extension to the method of Boatwright and Choy [1986] for determining the radiated seismic energy Es that accounts for factors that bias the estimate. We apply our technique to 204 events worldwide during the period 1992–1999 and find that the apparent stress is on average largest for strike‐slip events (0.70 MPa), while for reverse and ...
