The '''1967 Koynanagar earthquake''' occurred near [[Koynanagar]] town in [[Maharashtra]], India on 11 December [[Time in India|local time]]. The magnitude 6.6 shock hit with a maximum [[Modified Mercalli intensity scale|Mercalli intensity]] of VIII (''Severe''). It occurred near the site of [[Koyna dam]], raising questions about [[induced seismicity]], and claimed at least 177 lives and injured over 2,200.

==Damage==
More than 80% of the houses were damaged in Koyana Nagar Township,<ref name=Menon>{{cite news|title=Tremors may rock Koyna for another two decades|url=http://cities.expressindia.com/fullstory.php?newsid=151253|date=3 October 2005|author=Rajesh Menon|newspaper=[[The Indian Express]]|access-date=2009-01-05|archive-url=https://web.archive.org/web/20071117083928/http://cities.expressindia.com/fullstory.php?newsid=151253|archive-date=2007-11-17|url-status=dead}}</ref> but it did not 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 earthquake caused a {{convert|10|-|15|cm|abbr=on}} fissure in the ground which spread over a length of {{convert|25|km|sp=us}}. Some geologists believe that the earthquake was due to [[induced seismicity|reservoir-triggered seismic activity]],<ref name=Menon/> but senior project officials have repeatedly denied this conclusion.<ref name="Times_Of_India">{{cite news|url=http://timesofindia.indiatimes.com/city/pune/koyna-to-be-epicentre-of-global-study/articleshow/7706818.cms|title=Koyna to be epicentre of global study|author=Vishwas Kothari|newspaper=[[The Times of India]]|date=15 March 2011}}</ref>
