Session ID#: 17917

Session Description:
Induced and triggered seismicity is a common phenomenon, associated with fluid injection in geothermal exploitation, wastewater disposal operations, hydro-fracturing, CO2 sequestration, hydrocarbon production, mining operations, filling of reservoirs, and other fields such as volcano-seismology. Regions with pre-existing faults and increased fluid content are particularly sensitive. We invite papers that explore the empirical and statistical effects of injected fluids on temporal variations of physical parameters in reservoirs and natural environments, including stress and pressure changes and spatial-temporal patterns of seismicity among other. Of particular interest are fluid injections for enhanced geothermal systems and hydro-fracturing, fluid pathways and residence time, and fields such as volcano-seismology where induced and triggered seismicity is observed. We welcome submissions from a broad range of disciplines and aim to provide a platform for the discussion of occurrence, future monitoring, and hazard assessment of induced earthquakes.
