Radiation energy measured at earthquake source [PDF]
Geophysical Research Letters, 2005 We propose a new radiation energy, which is defined as an energy radiation measured close to the source. This energy enables us to rigorously handle the energy emitted not only from an earthquake but also from asperities of an earthquake. Therefore we can discuss a spatial variation of the radiation energy on the fault and compare it with the fracture ...

Dynamics, Radiation, and Overall Energy Budget of Earthquake Rupture With Coseismic Off‐Fault Damage [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractEarthquake ruptures dynamically activate coseismic off‐fault damage around fault cores. Systematic field observation efforts have shown the distribution of off‐fault damage around main faults, while numerical modeling using elastic‐plastic off‐fault material models have demonstrated the evolution of coseismic off‐fault damage during earthquake ...

Radiated energy and the physics of earthquake faulting [PDF]
Eos, Transactions American Geophysical Union, 2005 On the third day of a recent AGU Chapman Conference, held in Portland, Maine, near the Two Lights fault zones and the Fort Foster brittle zone, conference participants spent the gray June day scrambling over rocky ledges above the crashing surf along the coast of the Atlantic Ocean.With field trip leader Mark Swanson, who with his students has studied ...

Representations of the radiated energy in earthquakes [PDF]
Geophysical Journal International, 2005 We investigate the representation of the radiated energy, E_R, in earthquakes. In seismology E_R is estimated from either far-field seismic waves or the stress and displacement on the fault plane. Although E_R comes from the entire volume of the Earth, it can be expressed as an integral over the fault plane.

Atmosphere, 2021 We present a comprehensive analysis of pre-seismic anomalies as computed from the ground and space-based techniques during the recent Samos earthquake in Greece on 30 October 2020, with a magnitude M = 6.9.

The Earth's Surface Controls the Depth‐Dependent Seismic Radiation of Megathrust Earthquakes
AGU Advances, 2021 Megathrust earthquakes exhibit a ubiquitous seismic radiation style: low‐frequency (LF) seismic energy is efficiently emitted from the shallowest portion of the fault, whereas high‐frequency (HF) seismic energy is efficiently emitted from the deepest ...

Dissipation of Energy Radiated by Earthquakes
Annals of Geophysics, 2010 SUMMARY. - Representing radiated seismic energy as a sum of normal modes<br />we are able to develop approximate equations describing the dissipation of<br />this energy in the earth by solid friction. In particular we calculate total energy<br />radiated and spherically averaged dissipation as a function of depth.
