Borehole gas leak kills one, injures two in India
07 March 2016
A blast in Damoh district, Madhya Pradesh, killed a 65-year-old woman and injured two others in a house on March 5, with police and district authorities claiming that it was caused by “some unknown inflammable gas from below the earth’s surface”, according to the Hindustan Times.
Officials said that a preliminary investigation had revealed the explosion was caused by leakage of an inflammable gas which reached the house through a well borehole inside the premises.
The geologist Professor Arun Shandilya, who has studied the phenomenon of ground water catching fire in Madhya Pradesh for over a decade, said fissures in the ground enabled gas to leak to the surface.
According to the Hindustan Times, Prof Shandilya said the geology of the area involved the older Vindhyan rock layer covered by the geologically younger Deccan Traps layer, and when boreholes were sunk through the latter to the former, gas from the Vindhyan layer was sometimes released up to the surface.
In January, villagers in Damoh reported that ground water from borehole wells contained gas that burned with a blue flame, and many other instances of similar gas leaks have been reported in the area.
