PhD project: Modelling waves and earthquake rupture

Funding : Durham Doctoral Studentship

The aim of this project is to simulate earthquake rupture both in the laboratory, and numerically. We are interrested in methods to estimate how the stress builds up, and how waves propagate, before and during a rupture.

In the Rock Mechanics Laboratory, one analog model consists in polarized light passing through two birefringent plates (polycarbonate) which enables to visualize the stress field variation during ruptures. Acoustic emissions and strains are also measured with piezoelectric transducers, and strain gages, respectively. A triaxial apparatus is also used to reproduce earthquakes on simulated faults, under pressure representative of the earth's crust.

Finite difference and finite element models are used to support and understand the experimental observations.
