<p>Numerous source models for the mainshock have been inverted from seismic, geodetic, and tsunami observations. In this study is shown that, among six tested source models, there is a mean 47% gain in positively-stressed aftershock mechanisms over that for ...

<p>An earthquake alters the shear and normal stress on surrounding faults. New evidence strengthens the hypothesis that such small, sudden stress changes cause large changes in seismicity rate. Rates climb where the stress increases (aftershocks) and fall ...

Ten M>=6.7 earthquakes ruptured 1,000 km of the North Anatolian fault (Turkey) during 1939-92, providing an unsurpassed opportunity to study how one large shock sets up the next. Weuse the mapped surface slip and fault geometry to infer the transfer of stress ...
