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 ...

Earthquakes: Radiated Energy and the Physics of Faulting

2006
Earthquakes: Radiated Energy and the Physics of Faulting is the first book to present a systematic approach to understanding the energy changes associated with earthquakes. Solid Earth scientists, researchers and students -- especially those who work in seismology, tectonophysics, rock mechanics and geodesy -- will find this book an essential resource,

Teleseismic estimates of the energy radiated by shallow earthquakes

Journal of Geophysical Research: Solid Earth, 1986
The energy flux contained in the P‐wave groups (P + pP + sP) or the S‐wave groups (S + pS + sS) radiated by a shallow earthquake is modeled assuming that the energy flux in the direct and depth phases adds incoherently. By defining generalized radiation patterns which incorporate this neutral interference, the wave groups are analyzed as though they ...

A hybrid method for calculating the radiated wave energy of deep earthquakes

Physics of the Earth and Planetary Interiors, 1999
Abstract The energy radiated as waves is a parameter vital to the understanding of earthquake rupture physics. Calculations of this energy, however, are difficult and wrought with uncertainty. We developed a new hybrid method for the calculation of radiated wave energy and other key seismic parameters.

Spatial distribution of radiated seismic energy from earthquakes in Taiwan and surrounding regions

Journal of Asian Earth Sciences, 2020
Abstract The radiated energy during earthquakes is one of the essential characteristics that have a significant impact on human lives. The study of the released energy during earthquakes and their distribution may provide a detailed knowledge about the driving forces.

The seismic spectrum, radiated energy, and the Savage and Wood inequality for complex earthquakes

Tectonophysics, 1991
Abstract We have integrated velocity squared spectra in order to determine the seismic energy radiated during fault rupture. The high frequency spectral fall-off and the shape of the spectrum at the corner frequency are critical to the energy calculation.

Estimating high frequency energy radiation of large earthquakes by image deconvolution back-projection

Earth and Planetary Science Letters, 2016
Abstract High frequency energy radiation of large earthquakes is a key to evaluating shaking damage and is an important source characteristic for understanding rupture dynamics. We developed a new inversion method, Image Deconvolution Back-Projection (IDBP) to retrieve high frequency energy radiation of seismic sources by linear inversion of observed

Estimation of Radiated Energy of Finite-Source Earthquake Models

Bulletin of the Seismological Society of America, 2002
We estimated seismically radiated energy for kinematic earthquake rupture models. Instead of integrating far-field waveforms, we used an expression for radiated energy with slip and stress on the fault plane. Using an analytic crack model of Sato and Hirasawa (1973), we show that the finite-difference method can estimate the radiated energy fairly well;

Differential Energy Radiation from Two Earthquakes in Japan with Identical Mw: The Kyushu 1996 and Tottori 2000 Earthquakes

Bulletin of the Seismological Society of America, 2009
We examine two closely located earthquakes in Japan that had identical moment magnitudes M w but significantly different energy magnitudes M e . We use teleseismic data from the Global Seismograph Network and strong-motion data from the National Research Institute for Earth Science and Disaster Prevention’s K-Net to analyze the 19 October 1996 Kyushu ...
