Project Title: Stress Interaction and the Timing of Future Large Earthquakes
Supervisors: Dr. Sandy Steacy and Prof. John McCloskey
Level: PhD one or two students
Collaborator: Dr. Joan Gomberg, US Geological Survey - Memphis
Overview:
One of the most exciting areas of earthquake research is the application of
our growing understanding of earthquake interaction and triggering to the
rapid calculation of time dependent seismic hazard. While a number of
studies have clearly shown that stress changes due to large earthquakes can
affect the timing and location of future large events, research into the
calculation of time dependent earthquake probabilities is still evolving,
with only a limited number of tests of the best studied theoretical basis
for relating stress and probability changes.
The aim of this project is to systematically investigate large earthquakes
and the distribution of triggered earthquakes (if any) that follow them. The
aim in not to ask, What triggered this event? but rather What happened
after this event? This work will involve the computation of the stresses
that result from all chosen events and the examination of the temporal
distribution of the resulting triggered events. The main result will be a
definitive assessment of the level to which stress interaction modelling can
elucidate short-to-medium-term earthquake risk. In addition, the study will
allow for the testing of models of stress triggering probability.
