The Effect of Earthquake Source
2021This chapter explains the “effect of an earthquake source” on ground motion. Section 2.1 first briefly describes the history of seismology, where an earthquake is interpreted as a sudden movement of rocks along a source fault (“elastic rebound theory”) due to strain accumulated as a result of the interaction of the Earth’s plates (“plate tectonics ...

The Source of the Lisbon Earthquake
Science, 2005In his Perspective “What caused the Great Lisbon earthquake?” (27 Aug. 2004, p. [1247][1]) M.-A. Gutscher proposes an eastward-dipping subduction zone under the Straits of Gibraltar as a likely candidate responsible for the magnitude ( M ) 8.5 1755 Lisbon earthquake and associated tsunami ([1 ...

Source Parameters for Stick-Slip and for Earthquakes
Science, 1973Source parameters of stick-slip friction events measured in the laboratory show particle and rupture propagation velocities which are similar to those observed for earthquakes and inferred from seismic source theory. This dynamic similarity strongly supports the idea that stick-slip is the mechanism for shallow earthquakes.

Earthquake Source Fault Beneath Tokyo
Science, 2005Devastating earthquakes occur on a megathrust fault that underlies the Tokyo metropolitan region. We identify this fault with use of deep seismic reflection profiling to be the upper surface of the Philippine Sea plate. The depth to the top of this plate, 4 to 26 kilometers, is much shallower than previous estimates based on the distribution of ...

Source Mechanisms of Earthquakes
2014This book presents an innovative new approach to studying source mechanisms of earthquakes, combining theory and observation in a unified methodology, with a key focus on the mechanics governing fault failures. It explains source mechanisms by building from fundamental concepts such as the equations of elasticity theory to more advanced problems ...

On Quantification of the Earthquake Source
Seismological Research Letters, 2001The opinion article by Jones (Seism. Res. Lett. 71 , 395-396, 2000) and follow-up communications in Seismological Research Letters ( 71 , 670-672, 2000) discuss pros and cons of seismic moment vs. magnitude as scaling sizes for the earthquake source and possible related units.

An empirical study of earthquake source spectra for California earthquakes
Bulletin of the Seismological Society of America, 1997AbstractWe generalize source, path, and site effects for California earthquakes as functions of magnitude and distance, based on regression analysis of 1000 Fourier acceleration spectra from 43 California earthquakes in the moment magnitude range from 4.4 to 7.4, recorded at rupture distances from 1 to 200 km.

Source Mechanism of Earthquakes
1991Publisher Summary This chapter discusses the source mechanism of earthquakes that constitutes one of the most important subjects of seismology and has itself evolved into a large field in which numerous contributions have been made. The first mechanical model of the source of earthquakes is due to H. F.

The Nature of the Earthquake Source
1981The dynamics of crack formation, extension, and suturing is reviewed. Finite strength of materials regulates the rate of extension of cracks and allows for termination of the extension of cracks. Strength of materials is described mathematically by singular cohesive forces.
