New Delhi: The ministry of earth sciences (MOES) is set to begin deep drilling in the Koyna region of Maharashtra in October in an experiment that would let scientists study the causes of reservoir-triggered earthquakes of the kind that hit the Koyna Dam 48 years ago.
The $80 million experiment will run over five years, MOES secretary Shailesh Nayak said on Monday.
The Koyna region, close to the west coast of India, is considered an area of Reservoir Triggered Seismicity (RTS). Three years after builders completed the Koyna Dam, a 6.5-magnitude earthquake hit the area in 1967, killing more than 100 people. The phenomenon of dam-triggered earthquakes is known as reservoir-induced seismicity, but not much is known about the phenomenon.
As a part of the project, a research laboratory will be set up at Karad, Maharashtra, which will serve as the operational centre for the research activities related to the deep drilling. The laboratory will focus on borehole geophysics investigations and related research, including core analysis and associated field studies.
