Emile Okal

Emile Okal is a professor at Northwestern University, where he is affiliated with the Department of Earth and Planetary Sciences. He is a French-American seismologist with decades of research on oceanic and deep seismic events.

Okal specializes in large oceanic earthquakes and deep-focus earthquakes, which occur at great depths within subducting tectonic plates. His work on seismic source physics helps distinguish which undersea quakes are likely to generate dangerous tsunamis.

Okal has contributed extensively to understanding tsunami generation mechanics, including criteria for evaluating whether a particular seismic event will produce a significant tsunami. His research has informed how tsunami warning centers assess oceanic earthquake threats.

Okal has published analyses of several major oceanic earthquakes and tsunami events throughout his career at Northwestern University. His work frequently addresses the relationship between earthquake fault mechanics and the resulting wave propagation across ocean basins.
