[ARCHIVED] "Science Café - Linking the Dynamics and Composition of Earth's Interior

Earth Interior

The Museum of Nature & Science and Sigma Xi present “Science Café – Linking the dynamics and composition of Earth’s interior to surface processes” with guest speaker Lauren Waszek, Ph.D. Dr. Waszek joins us via Zoom at 5:30 p.m. on Tuesday, August 17 from James Cook University in Queensland, Australia. Please contact Stephanie at for a link to the program or go to with webinar ID 89222506770. 

Seismology is the only tool to observe Earth’s interior, using energy from earthquakes to make detailed detections. By combining seismological observations with geodynamical modelling and mineral physics calculations we can understand the mechanisms of mantle convection. Learn about the relationship between seismic features in the upper and mid-mantle to its temperature and composition, and the resultant geodynamical influence for volcanism on Earth’s surface. 

Dr. Lauren Waszek is a global seismologist currently lecturing in physics at James Cook University through an Australian Research Council Discovery Early Career Research Award fellowship. There, she researches mantle discontinuities, with a particular focus on the dynamics and composition of the structures associated with the Australian tectonic plate and recently joined the Mars InSight team. 

The Museum of Nature & Science is located at 411 N. Main Street and is accessible from RoadRUNNER Transit Route 1 Stop 36. For additional information, visit the website at: or follow us on Facebook and Instagram @LCMuseums
