Strong motion simulation based on dynamic rupture modelling: A case study on the 1999 Düzce earthquake

Dr. Luis A. Dalguer (ETHZ), Dr. Gulum Tanircan (Bogazici University, Turkey)

Here we investigate the dynamic rupture of the 1999 Duzce earthquake and the ground motion generated, fitting model prediction with observations. Our goal is to understand the underlying physics during this earthquake that ruptured with supershear speed, and the implications in the ground motion. The figure below shows preliminary results of final slip and rupture time for this earthquake.

The computation demand for this work is also very high, because it require highr resolution and large scale simulations to accurately solve the problem . We are currently using a large memory sharing SUN machine with 8 processors and 64 Gbytes.
