Reservoirs and earthquakes

In 1982 the U.S. Army Corps of Engineers published a study of reservoir-induced seismicity. The study evaluated the evidence of induced earthquakes from eight cases including Koyna, Hoover, Nurek, and Kariba. In this paper, the methods used in the 1982 study are applied to more recent data from Koyna and Aswan. The data from Aswan do not support classification of the 1981 earthquake as reservoir-induced. The data from Koyna confirm the findings of the 1982 study that the earthquakes at Koyna are not closely correlated to the reservoir operation.
