Fault branching and rupture directivity

  title={Fault branching and rupture directivity},
  author={Sonia Fliss and Harsha Bhat and Renata Dmowska and J. D. Rice},
[1] Could the directivity of a complex earthquake be inferred from the ruptured fault branches it created? Typically, branches develop in forward orientation, making acute angles relative to the propagation direction. Direct backward branching of the same style as the main rupture (e.g., both right lateral) is disallowed by the stress field at the rupture front. Here we propose another mechanism of backward branching. In that mechanism, rupture stops along one fault strand, radiates stress to a… CONTINUE READING
