Determination of effective tectonic stress associated with earthquake faulting. The Tottori earthquake of 1943
TLDR
In this paper, the authors used the records of the Tottori earthquake of 1943 (M = 7.4, 35.5° N, 134.2° E, depth 10 km) about by a low-magnification seismograph at a relatively short distance to determine dynamics fault parameters such as the particle velocity and the effective tectonic stress.About:

Theoretical basis of some empirical relations in seismology
Hiroo Kanamori,Don L. Anderson +1 more
TL;DR: In this article, an empirical relation involving seismic moment M, energy E, magnitude M, and fault dimension L (or area S) is discussed on the basis of an extensive set of earthquake data (M_S ≧ 6) and simple crack and dynamic dislocation models.
Journal ArticleDOI
The energy release in great earthquakes
TL;DR: In this paper, a new magnitude scale M_w is defined in terms of W_0 through the standard energy-magnitude relation log W_ 0 = 1.5M_w + 11.8.
Journal ArticleDOI
Inversion of complex body waves
Masayuki Kikuchi,Hiroo Kanamori +1 more
TL;DR: In this article, the authors developed a method that inverts seismic body waves to determine the mechanism and rupture pattern of earthquakes, where the rupture pattern is represented as a sequence of subevents distributed on the fault plane.
Journal ArticleDOI
Scaling relations for earthquake source parameters and magnitudes
TL;DR: In this article, the authors derived scaling laws for kinematic fault parameters such as length, width and rise time in terms of fault length and width, respectively, from a data set of 41 moderate and large earthquakes.
Journal ArticleDOI
A spectral theory for circular seismic sources; simple estimates of source dimension, dynamic stress drop, and radiated seismic energy
TL;DR: In this article, the far-field body wave radiation from a class of circular rupture models is investigated as a function of takeoff angle, rupture velocity, and stopping behavior, and the variation of spectral shape, pulse shape, and energy flux over the focal sphere is quantified.

Tectonic stress and the spectra of seismic shear waves from earthquakes
TL;DR: In this paper, an earthquake model is derived by considering the effective stress available to accelerate the sides of the fault, and the model describes near and far-field displacement-time functions and spectra and includes the effect of fractional stress drop.

Elastic displacements in the near-field of a propagating fault
TL;DR: In this article, the authors computed the displacement, particle velocity, and acceleration wave forms in the near field of a propagating fault by numerical integration of the Green9s function integrals for an infinite medium.
Journal ArticleDOI
Seismic displacements near a fault
TL;DR: In this article, the authors compared the observed and theoretical seismograms of the Parkfield earthquake of June 28, 1966, by the accelerographs of the U.S. Coast and Geodetic Survey and concluded that the fault dislocation was about 60 cm.
Journal ArticleDOI
Energy Release in Earthquakes
TL;DR: In this paper, the authors extended the notion of static elasticity to include the problem of the energy release upon the introduction of a tear fault into an otherwise homogeneous medium subjected to a uniform shear stress.
