Poroelastic stress relaxation, slip stress transfer and friction weakening controlled post-injection seismicity at the Basel Enhanced Geothermal System
Abstract
Post-injection seismicity at the enhanced geothermal system of Basel, Switzerland, was caused by poroelastic stress relaxation of stabilized faults during injection, according to numerical simulations of the stress field applied on a fault network.
