Imaging of earthquake sources

International Journal of Imaging Systems and Technology, 1990
AbstractElastic waves, produced by temporally and spatially finite fault ruptures during earthquakes, propagate through the Earth. Recordings of these waves at the Earth's surface provide the data for reconstruction of the source properties, including location, spatial and temporal extents, and rupture velocities. A 2D finite‐difference solution of the

Earthquakes: Simulations, Sources and Tsunamis

Pure and Applied Geophysics, 2008
Large earthquakes pose an almost incalculable risk, causing great destruction and, often, loss of life. While large regions of the world are susceptible to this potentially devastating natural hazard, the Asia-Pacific region is particularly vulnerable.

Earthquake source arrays

2020
A collection of earthquake sources recorded at a single station, under specific conditions, are considered as a source array (SA), that is interpreted as if earthquake sources originate at the station location and are recorded at the source location.

Motion at the source of an earthquake

1957
Nakano's theoretical development emphasizes the effect of seismic disturbances at large distances from the source and develops equations of first motion in P and S for several types of source mechanisms. These equations are compared to the methods of approach of various investigators, and two mechanisms in particular are singled out: a single couple ...

The Effect of Earthquake Source

2021
This 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, 2005
In 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, 1973
Source 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, 2005
Devastating 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 ...
