Geological assignments refer to the correlation between the drilling results of the frontal wedge and those of the Pacific Ocean floor20. Labels ?F1 to F4 indicate faults in the trench axis. Geometries of F1 and F2 are our original interpretation, while those of F3 and F4 follow literature2....
The two earthquakes differ primarily in the dip direction of the faults and the depth of faulting. The 1971 north-northeast trend of left-lateral faulting (Chatsworth trend) was not activated in 1994. 展开 关键词: Experimental/ earthquakes faulting seismology tectonics/ United States USA seismicity...
Local crustal spreading is required by the geometry of dextral offsets when, as in the San Andreas system, faults have dominantly strike-slip motion with right-lateral displacement. Three clear examples of this relation occur in the Imperial Valley, Coso Hot Springs, and the Danville region, ...
Recent damaging earthquakes in California, including the 1971 San Fernando, 1983 Coalinga, 1987 Whittier Narrows and 1994 Northridge events, have drawn attention to thrust faults as both potentially hazardous seismic sources and as a mec... C Walls,T Rockwell,K Mueller,... - 《Nature》 被引量...
The absolute value of the Fourier transform of the displacement field radiated by an earthquake in the far field. For almost all earthquakes it has a common shape: flat at low frequencies and decays like the inverse squared power at high very high values of frequency. ...
14. The data confirm the slip-rates and strain-rates averaged over 15 ± 3 ka in Fig.1, but reveal periods of rapid slip on some faults, with up to 15 m of slip in as little as 3500 years, that are contemporaneous with periods of low or no slip on neighboring faults ...
The earthquake size-frequency distribution of individual seismic faults commonly differs from the Gutenberg-Richter law of regional seismicity by the presence of an excess of large earthquakes. Here we present a cellular automaton of the forest-fire model type that is able to reproduce several size-...
