Prof. Polet expertise is in earthquake source processes, tsunami-genesis, and practical applications of seismology to reduce hazards from earthquakes. Her work includes the measurement and interpretation of characteristics of earthquakes that occur in subduction zones and their tsunamigenic potential. Additional research interests include the exploration of the shallow subsurface for detection of shallow faults and the development of seismic hazard and microzonation maps.
