Abstract. We report here the salient features of the recently concluded International Continental Scientific Drilling Program (ICDP) workshop in Koyna, India. This workshop was a sequel to the earlier held ICDP workshop in Hyderabad and Koyna in 2011. A total of 49 experts (37 from India and 12 from 8 other countries) spent 3 days reviewing the work carried out during the last 3 years based on the recommendations of the 2011 workshop and suggesting the future course of action, including detailed planning for a full deep drilling proposal in Koyna, India. It was unanimously concluded that Koyna is one of the best sites anywhere in the world to investigate genesis of triggered earthquakes from near-field observations. A broad framework of the activities for the next phase leading to deep drilling has been worked out.

Short summary
During May 16-18, 2014, the ICDP Workshop on Scientific Deep Drilling in the Koyna region of western India was held in Koyna to review the progress made in the preparatory phase and the preparation of a full drilling proposal. 49 participants came from Canada, France, Germany, India, Japan, New Zealand, Norway, Spain, and USA. It was recommended to have two pilot and two main boreholes, hosting comprehensive sets of monitoring instruments to better comprehend reservoir-triggered earthquakes.
