Distinguished Speaker Stamps reveals "Clues About the Break-up of the African Continent"
EES' Distinguished Speaker this week is Dr. Sarah Stamps of Virginia Tech.
"Clues About the Break-up of the African Continent"
The African continent is slowly fragmenting into 5 small pieces along the East African Rift System (EARS) across east Africa. What drives this process and how exactly are these pieces of Earth's crust moving? In this seminar Stamps presents data that shows how the tectonic plates of the EARS are slowly moving and deforming causing hazardous seismic and volcanic activity. Using modern-day, high precision positioning measurements from Global Navigation Satellite Systems (GNSS) and advanced numerical modeling, she models the physics driving surface motions to understand the driving forces causing the break-up of Africa. She finds that deformation is characterized by east-west extension and the major forces driving surface motions are derived from topography gradients. Deeper processes are responsible for the distribution melt beneath magma-poor rifts.
Join us for this revealing look at the African continental breakup on Friday, November 8, 2019 in Room 204, Natural Science Building on the East Lansing Campus.
