Rupture Dynamics on Rough and Segmented Faults

Rupture Dynamics on Rough and Segmented Faults

Internship Description

In this project, the student will conduct numerical experiments to study the dynamic rupture process and associated radiated seismic energy for faults and simple fault systems that comprise (a) fractally rough fault surfaces and (b) canonical models of segmentation. In part (c), the approaches (a) and (b) are combined to obtain a first-order understanding how small-scale fault roughness may affect rupture-transition properties at segment boundaries. The student will initially test two available HPC-enabled dynamic-rupture simulation codes in terms of performance and for code verification. ​​​​

Deliverables/Expectations

+ compare two codes/methods using identical numerical parameterization

+ examine rupture process and seismic radiation for various degrees of fault roughness

+ study the rupture jumping (branching vs. jumping) behavior in case of idealized large-scale segmented but small-scale rough faults

+ document results in oral (group-seminar talk) and written (report) form
