Watch

In this talk recorded at the UT Austin Jackson School of Geosciences, PI Elizabeth Catlos presents a critical reassessment of standard Himalayan earthquake models in the wake of the 2015 Gorkha earthquake (Mw 7.8).

• Why the 2015 rupture didn’t behave as predicted by conventional MHT models.
• Evidence for additional active fault systems beyond the Main Himalayan Thrust.
• The case for the Judi, Thaple, Gaurisankar, and Pokhara lineaments as active structures.

Speaker: Elizabeth Catlos, University of Texas at Austin, Jackson School of Geosciences
