Basic Research Topics

Kinematic modeling of earthquake sources; Determination of the spatio-temporal characteristics of earthquake rupture by i) inversion of full waveforms at regional and/or teleseismic distances, geodetic data, strong ground motion records and surface offset data and ii) inversion of relative source time functions
Variability of strong ground motion due to source and site effects
Near-fault effects on strong ground motion
Simulation of strong ground motion using both deterministic (Empirical Green's Functions) and stochastic approaches with emphasis on the incorporation of the finite-source and directivity effects
Near real-time applications for the computation of earthquake source parameters (fast moment tensors) and shake maps for earthquakes in areas covered by sparse networks
Moment tensor determination
Study of non-linear site response during earthquakes
Seismicity studies (relocation, determination of source parameters, seismotectonic implications)
