The mechanism of induced seismicity

Mehr zum Buch

This work explores various aspects of seismicity, focusing on induced microseismicity and its implications across different geological settings. It begins with an analysis of seasonal seismicity in Northern California prior to the 1906 earthquake and examines post-seismic effects from a significant earthquake in a flooded mine. The influence of heavy rainfall on microseismicity around vertical ore veins is also discussed. The reliability of seismic moment tensor inversions for induced microseismicity is evaluated, alongside the impact of rock properties on mining-induced seismicity in South Africa. Further sections delve into the mechanics of microearthquake sequences, simulation of fault slip in granite, and the modeling of seismic waves in fractured rock. The text covers tomographic imaging of thermally induced fractures and presents an analogue experiment addressing earthquake sequence decay patterns. Case studies highlight induced microearthquake patterns in hydrocarbon and geothermal reservoirs, alongside seismological studies related to fluid injection in sedimentary rocks. The work also addresses production-induced faulting in oil fields and the application of induced seismicity data for detecting deformation processes in hydrocarbon fields. Techniques such as Kalman filtering for microseismic event detection and detailed evaluations of fracture systems in geothermal fields are examined, concluding with a discussion o
