The Fracture Mechanics of Induced Seismic Events: Problems and Advances
Induced seismicity is a real problem in highly industrialized and densely populated areas. During the last years a lot of case studies has been carried out giving information about the most general seismological and rock-mechanical features of the induced events triggered by different technical processes, including nuclear blasts.
In the paper some rock-mechanical and seismological features of the fracture process within the source as well as the most important natural preconditions on a site for triggering of induced events are presented.
A lack of knowledge still exists in clear and quantitative (seismological) criteria to distinguish between natural tectonic earthquakes and induced ones in a certain region. On the other side the reliable discrimination between natural and induced earthquakes is very important for understanding of the fracture mechanism and for mitigation of the danger resulting from induced seismic events as well as for the evaluation of technical processes with respect to the triggering potential of induced seismic events.
