Deployment of 10 seismometers for monitoring the induced seismicity of the Lacq gas field, France. This project focus on the analysis of the seismicity induced by anthropogenic activities (gas extraction and wastewater injection) related to the gas field, located in Lacq, France. We aim to answer the following questions: which part of the Lacq induced seismicity is generated by wastewater injection? by the mechanical evolution of the reservoir depletion? Is the seismicity confined to the (minor) faults of the reservoir or can regional tectonic faults be activated, generating large earthquakes? What scenarios of ground shaking & damages could be expected in case of a major event in the area? What is the associated seismic hazard & risk?
