Crack models of small repeating earthquakes

I use fracture mechanics concepts to derive analytical expressions for the recurrence interval of repeating earthquakes, which explain the surprising scaling observed in nature.

Dynamic Triggering at Oceanic Transform Faults

I use stastical tools to analyze data from ocean bottom seismometers in the East Pacific Rise, and detect instances of dynamic earthquake triggering from remote mainshocks.

Earthquake Cycle and time-dependent coupling in Subduction Zones

Using 2-D simulations and fracture mechanics concepts, I am investigating the seismic cycle of subduction zones.

Seismic swarms and aseismic slip driven by dikes

In a seismic swarm during the 2000 Miyakejima dike intrusion we find evidence of aseismic slip on a complex fault system.

Static stress triggering in Operational Earthquake Forecasting

During my PhD, I have developed new models of seismic sequences based on stress interaction. Now I am involved in collaborations aimed at further refining and developing and testing them.
