Lecture: "The 65.5 Million Year Old Chicxulub Impact Crater: Insights into Planetary Processes"

Tue, April 2, 2013 • 6:30 PM - 7:30 PM • Amphitheater, ATT Conference Center

An extra-terrestrial body impacted the Earth in the region that today is the Yucatán Peninsula (Mexico) 65.5 million years ago, causing worldwide devastation that almost certainly was the principal cause of a mass extinction event famous for ending the age of the dinosaurs. This presentation will describe the working hypothesis for the formation of the Chicxulub and its impact, discuss how researchers test this hypothesis, and explain the goals of an upcoming drilling expedition to the crater in the next couple of years. Learn how geophysicists use modern computing to investigate the deep history of the Earth.

Sean Gulick is a Research Associate Professor in the Institute for Geophysics at UT Austin. His primary scientific interest is the examination of deformation of the Earth. Current projects include examining tectonic and glacial climate linkages in Alaska, investigatinos of geophysical images of the Chicxulub impact crater, and many others.

Free and open to the public.  Please RSVP to For more information, vist The Austin Forum.
