Slip rates and base level changes on the Main Frontal Thrust, Nepal

In 2014 and 2015, the Structural Geology group at EOS conducted seismic reflection acquisition in Nepal across the Main Frontal Thrust to constrain its geometry and kinematics. These lines reveal both sedimentary evidence of base level change and growth strata deposited at the fault tip of a strand of the MFT that appear to record several individual earthquake events. Starting in February 2017, drilling and coring of these layers took place, with the goal of dating the changes in base level and slip.

In 2018, we completed the drilling phase of this project and completed logging all cores.
