DEVELOPMENTS IN GEOTECHNICAL ENGINEERING 11: DAMS AND EARTHQUAKES

This summing up of the present-day knowledge on earthquakes associated with large artificial lakes, discusses and assesses the focal parameters and macrosiesmic effects of the Koyna (India) multiseismic earthquake. The geology, hydrology and seismicity of all known seismic reservoir sites is covered, and 3 known cases of induced seismicity following the fluid injection in deep wells are also similarly treated. The characteristic seismic features of reservoir-associated earthquakes and how they reflect upon the changes in mechanical properties of rock masses near the reservoir are described, and procedural details of the calculation of the stresses added by a reservoir are outlined. Theoretical and laboratory experiments on the effect of pore pressure in causing shear failure are reviewed, and the part played by increased pore-fluid pressures in triggering the earthquakes at Denver, Ragely, Kariba, Kremasta and Koyna is examined. Recent developments in fluid-flow stress analysis and in-situ measurements of stresses are described briefly. Comments are also made on why certain large reservoirs are aseismic.
