Environmental Seismology

My research on this topic is focused on non invasive seismic noise correlation techniques to retrieve the water table in a slow moving deep seated landslide (Utiku, NZ).

I have developed a robust measurement of the velocity variations at a local scale to track the changes of the water table. The measurements are validated by a Biot-Gassman modeling of the saturation changes (coll. Stéphane Garambois, UGA).

In parallel, we develop laboratory experiments at a decimetric scale to investigate the precise effect of saturation changes on the seismic velocities and on the noise correlation monitoring (coll. Daniel Brito, Valier Poydenot, Clarisse Bordes, UPPA).
