Abstract

Summary

Water, brine, and co2- rich fluids, generally found in fault zones, characterize the long-term strength and rupture distribution in these regions. Furthermore, they produce a large electrical resistivity contrasts with their surroundings, utilizing EM exploration methods like magnetotelluric (MT) as a proper tool to monitor co-seismic variations of physical parameters in a seismogenic zone. To address the question of whether the residual of pre- and post-seismic MT responses can monitor well the physical properties in the rupture area of an earthquake, we investigate a synthetic MT example of an active fault zone.
