Description
The WP4 work package is dedicated to understanding the geomechanicalcauses and processes of induced seismicity in various contexts and at various scales. Different modeling approaches and laboratory experiments have been performed to investigate some of the key factors influencing induced seismicity: the goal is to develop physical concepts to help explain the interaction of pore-pressure changes, temperature decrease, fault activation (including dynamic rupture) and seismic event magnitudes.
This report corresponds to the deliverable D4.3 for the GEISER project. It gathers the work performed by the different partners within task 4.1, referred to as “Role of pore pressure changes”:
- The laboratory experiments performed by GFZ on the monitoring of induced micro-seismicity from fluid injections,
- The core samples from Icelandic geothermal sites provided by ISOR,
- The study on the structural heterogeneities compartmenting sedimentary reservoirs performed by TNO,
- The study performed by GEOWATT on how the Stress Coulomb changes can be used for assessing seismic hazard,
- The work performed by INGV on time-dependent variation of pore pressure with a fluid dynamic approach.
