Statistical seismology, slow earthquakeOverview of the research
A wide variety of slow fault-slip phenomena, called slow earthquakes, occur in subduction zones worldwide. These slow earthquakes sometimes trigger great earthquakes and earthquake swarms. I am working to improve probabilistic forecasts of seismicity by considering the effect of slow earthquakes on triggering seismicity. In addition, I am interested in the diversity of fast and slow seismicity in subduction zones worldwide and their origins.
