Keep an eye on this

A USD80-million research project at India’s Koyna dam site will study reservoir-triggered earthquakes (aka reservoir-induced seismicity) and the causes behind them. Dam activity at Koyna was blamed for a powerful earthquake in 1967 that destroyed the village of Koynanagar in western India’s Maharashtra state, left 180 people dead, 1,500 injured, thousands homeless and power cut off to Bombay.
