Anthropogenic Triggering of Large Earthquakes
The physical mechanism of the anthropogenic triggering of large earthquakes on active faults is studied on the basis of experimental phenomenology, i.e., that earthquakes occur on active tectonic faults, that crustal stress values are those measured in situ and, on active faults, comply to the values of the stress drop measured for real earthquakes, that the static friction coefficients are tho...
متن کاملTeleseismic Time Functions for Large, Shallow Subduction Zone Earthquakes
Broadband vertical P-wave records are analyzed from 63 of the largest shallow subduction zone earthquakes which have occurred in the circum-Pacific in the last 45 yr. Most of the records studied come from a common instrument, the Pasadena, California, Benioff 1-90 seismometer. Propagation and instrument effects are deconvolved from the P-wave records using a damped least-squares inversion to ob...
متن کاملComparisons of dynamic triggering near Beijing, China following recent large earthquakes in Sumatra
[1] Dynamic triggering around the Fangshan Pluton near Beijing is repeatedly identified. Here we report clear triggered events in this region during the surface waves of the 2012 Mw8.6 Sumatra earthquake. However, we do not find any triggered events during the G2 waves of the Mw8.6 event, and the surface waves of the Mw8.2 Sumatra earthquake that occurred two hours later. The peak ground veloci...
متن کاملShort Notes Epicentral Confidence Regions of Nuclear Test Events at Teleseismic Distances
The accurate location of seismic events is a basic discriminant for underground nuclear test monitoring (Bolt, 1976; Dahlman and Israelson, 1977; Blandford, 1982). Of particular interest are determining epicentral confidence regions and providing constraints on estimated focal depths. In this study, only routine teleseismic P travel-time data are used, as provided by worldwide stations reportin...
