Earthquakes as dynamic fracture phenomena
http://www.rosakis.caltech.edu/downloads/pubs/2000/93%20Dynamic%20Failure%20Mechanics%20AJR%20GR.pdf 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.
