My research is in the general area of operational earthquake forecasting, in essence the determination of time dependent changes to earthquake probabilities. My work focuses on the computation of Coulomb stress changes which affect earthquake likelihood in time and space, and in combining this physics based approach with geological and statistical models. I was a member of the expert elicitation panel on future seismic hazard in the Canterbury region whose work informed the revised building codes in Christchurch, New Zealand. I was also lead editor of a special issue of the Journal of Geophysical Research on ‘stress transfer, earthquake triggering, and time-dependent seismic hazard’, and am lead author of the review paper that introduces the volume.
Current research activities
- Developing hybrid Coulomb-statistical models for forecasting aftershock rates.
- Analysing the controls on Coulomb triggering in earthquake sequences.
- Assessing the scientific constraints on the applicability of the Coulomb stress technique to time dependent earthquake hazard.
- Investigating methods of communicating changes in earthquake probability
Previous research activities
- Investigated stress interaction and earthquake triggering in a complex 3-D fault network model.
- Modelled the next likely earthquake and tsunami to affect the island of Sumatra.
- Formulated realistic stress transfer rules to simulate stress concentrations in cellular automata models of the earthquake process.
- Investigated earthquake nucleation, rupture, and statistics in heterogeneous cellular automata.
- Developed hybrid cellular automaton – elastic model to simulate mining induced seismicity.
- Investigated temporal and spatial seismicity patterns with heterogeneous bond-breaking computer model.
- Interpreted frictional parameters with physical model that included effects of dilatancy on transients associated with velocity steps.
- Calculated shear strength of natural faults and scaling of frictional parameters with damage mechanics formulation.
- Developed cellular automaton to simulate fractal fragmentation.
