Large earthquakes are sometimes observed to trigger other large earthquakes on nearby faults. The magnitudes of the calculated Coulomb stress transfers presumed to cause the triggering are 10 –10 3 of the earthquake stress drops. The earthquake stress drops and the triggering delay times are similarly small with respect to the natural recurrence time of the earthquakes. This requires that both ...

We developed a sliding-window cross-correlation (SCC) detection technique and applied the technique to continuous waveforms recorded by the Cooperative New Madrid Seismic Network stations following the 18 April 2008 Illinois earthquake. The technique detected more than 120 aftershocks down to ML 1.0 in the 2 week time window following the mainshock, which is three times more than the number of ...

Geophysical data from the offshore Cascadia forearc reveal many Quaternary upper-plate faults and folds. Most active structures are within the accretionary wedge, but significant deformation is also found on the continental shelf. Several faults and synclines project into adjacent coastal bays where deformation of Pleistocene marine terraces is reported. Rapidly buried marsh deposits and drowne...

This study investigated the psychological reactions of survivors of the 512 Wenchuan earthquake in China and the risk factors associated with those reactions. The Impact of Event Scale-Revised (IES-R), Type D Scale-14 (DS14), a self-developed trauma experience questionniare, and a demographic questionnaire were administered to 956 earthquake survivors (389 males and 567 females) in Mianzhu, one...

Changes in species assemblages of intertidal foraminifera can be used to estimate the amount of earthquake-related subsidence during plate-boundary earthquakes at the Cascadia subduction zone. The accuracy and precision of foraminiferal methods in paleoenvironmental reconstruction is underpinned by the relations between contemporary taxa and their environment, which are used to calibrate fossil...

landslide like phenomena such as earthquake, flood, and volcano eruption are considered as the important natural events which happen every year in the mountainous and the elevated regions of the country and incur substantial damages and losses. today, in the countries involved with the issue of earthquake sliding, there is an increasing tendency in evaluating and zoning of the danger and damage...

The 11 March 2011 Tohoku earthquake (05:46:24 UTC) involved a massive rupture of the plate-boundary fault along which the Pacific plate thrusts under northeastern Honshu, Japan. It was the fourth-largest recorded earthquake, with seismic-moment estimates of 3–5 × 10 N·m (Mw 9.0). The event produced widespread strong ground shaking in northern Honshu; in some locations ground accelerations excee...
