摘要

At the Koyna reservoir in western India, it is observed that earthquakes of magnitude (M) 4-5 are often preceded by well-defined clusters of foreshocks of M <= 3, referred to as nucleation that is found to last typically for 100-400 h. Based on continuous monitoring of seismic activity, a nucleation pattern was identified and an earthquake of M 4+ was forecasted on 16 May 2006. An earthquake of M 4.2 did occur on 21 May 2006 within the forecasted parameters. The continued seismic activity in such an isolated and well-monitored site probably makes Koyna a suitable locale to pursue meaningful study of earthquake precursors.
