23rd Annual Paul D. Bartlett, Sr. Lecture

The central and eastern portions of the U.S. have a fascinating geological history. However, much of that history is captured in the crust and upper mantle beneath our feet, much deeper than we can sample directly. Geophysical imaging gives us a way to “see” into the interior of the North American continent, and now high-resolution data from the recent EarthScope project have yielded spectacular new insights into how continental North America has evolved over geological time.

In this talk, Maureen Long, the Bruce D. Alexander '65 Professor and Chair of Earth & Planetary Sciences at Yale, will give an overview of how geophysicists image the Earth’s interior by measuring earthquake waves. She’ll also update us on recent discoveries about the structure and evolution of the central and eastern U.S., and what they might tell us about why earthquakes happen far away from tectonic plate boundaries.
