Worldwide, the biggest RTS earthquake of magnitude M 6.3 occurred on 10 December 1967 at Koyna, India. From among RTS sites globally, at four sites destructive earthquakes exceeding magnitude 6 occurred. RTS at Koyna has continued until now, whereas at other sites it ceased in a year to a few years. Detailed studies of RTS sequences carried out in 1970s led to delineating common characteristics of RTS events that also help in differentiating RTS sequences from normal earthquake sequences. Association of water level changes in the Koyna and Warna reservoirs and RTS in the Koyna region has been well established. The part played by reservoirs in triggering the earthquakes is not well understood, due to lack of near‐field studies. Koyna is found to be a very suitable site for such studies. The suitability of the Koyna site for setting up a deep borehole laboratory and the scientific work to be carried out were discussed in an International Continental Drilling Program (ICDP) supported workshop held in India in 2011. The suggested additional work to be carried out was undertaken from 2011 to 2014 and discussed in the second ICDP Workshop held in 2014. A go‐ahead was given for putting up a pilot borehole of 3000‐m depth. The pilot borehole drilling started in December 2016 and was completed in June 2017, along with necessary observations and studies. These were presented in the Post Operation Workshop held during October 2017. A few salient features of the work carried out in the last 50 yrs are presented here.
