Earthquakes as dynamic fracture phenomena

Web[2] Earthquakes are dynamic rupture propagation along fault planes, starting from an elastodynamic instability within a small region. Some earthquakes grow to devastat- ing events while most remain small. WebAbstract. The high degree of similarity between earthquakes and fractures strongly supports the fracture hypothesis of earthquakes. From this standpoint the stochastic …
