About the Event: 

Many natural hazards have been well known and qualitatively understood for decades, but still lack accurate measures of how damaging future events will be. For example, despite many years of research, it still remains a question as to how much variability in ground motions one should expect of a large San Andreas type earthquake, and whether early warning for debris flows can be successfully implemented. In this talk, I address both of these questions by using simple but physically sound mechanical principles to quantify certain aspects of these hazards.

About the Speaker: 

Professor Victor Tsai is interested in a wide range of geophysical topics, including wave propagation and imaging, and understanding the mechanics of various solid-fluid interactions like glaciers with meltwater and sediment transport in rivers. On the imaging and inversion side, he is interested in both structural inversions, particularly using surface waves and ambient noise, and also earthquake inversions, particularly using overdetermined parameterizations. On the mechanics side, he is interested in earthquakes, glaciers, tsunamis, landslides, debris flows, volcanoes, rivers, and other planetary bodies.
