abstract="We review the &quot;critical point&quot; concept for large earthquakes and enlarge it in the framework of so-called &quot;finite-time singularities.&quot; The singular behavior associated with accelerated seismic release is shown to result from a positive feedback of the seismic activity on its release rate. The most important mechanisms for such positive feedback are presented. We solve analytically a simple model of geometrical positive feedback in which the stress shadow cast by the last large earthquake is progressively fragmented by the increasing tectonic stress.<p /><p>Language: en</p>",
