S015:
Fifty Years since the World’s Largest Reservoir Triggered Seismic (RTS) Event, the 10 December 1967 M6.3 Koyna Earthquake – Lessons learnt





Session ID#: 25383

Session Description:
The 10th of December 2017 marks 50 years since the M6.3 Koyna Earthquake (1967) in Western India, which is recognized as the world’s largest Reservoir Triggered Seismic (RTS) event. Despite the large amount research about this event, a definitive model for RTS mechanism has been elusive and several critical issues remain unresolved. With this in mind, this session will cover various aspects of RTS in Koyna and its relation to evolution of the Deccan Traps, as well as other sites globally. We invite presentations that include observations and modeling of earthquake patterns, seismogenic faults, the stress field, subsurface structure, neotectonics, geomorphology and patterns of surface deformation, hydrogeological and geophysical characteristics, rock mechanical properties inferred from lab or field studies, recurrent triggered seismicity and its relation to local tectonics, modeling of RTS and its predictability, multi-parametric precursory observations and prediction of triggered seismicity.
