The 1967 Koynanagar earthquake occurred near Koynanagar town in Maharashtra, India on 11 December. The 6.5 magnitude shock hit near the site of Koyna dam and claimed at least 180 lives and injured over 1,500. More than 80% of the houses were damaged in Koyana Nagar Township,[1] but it didn't cause any major damage to the dam except some cracks which were quickly repaired. There have been several earthquakes of smaller magnitude there since 1967. The deadly earthquake caused a 10–15 cm (3.9–5.9 in) fissure in the ground which spread over a length of 25 kilometers (16 mi).

Some geologists believe that the earthquake was due to reservoir-triggered seismic activity.[1] Senior project officials have repeatedly denied this conclusion.[2]
