Is there a volcano about 100 to 110 km from Kalpakkam?

Is there a volcano about 100 to 110 kilometre from Kalpakkam nuclear Plan? That is what nuclear and geology experts are trying to ascertain after The Global Volcanism Program, a hub of an international network for monitoring, reporting, and maintaining data related to volcanic activity around the world, reported a volcanic sighting in 18th century. 

Chairman and managing director of Bharatiya Nabhikiya Vidyut Nigam Limited, Dr Prabhat Kumar, who has formed a committee of nuclear experts and geologists, said the information in Smithsonian’s Global Volanism Programme website about a reported volcano about 100-110 km from Kalpakkam is far-fetched but the committee is investigating all the aspects.

Interestingly, the committee, that consists of eminent scientists from Indira Gandhi Centre for Atomic Research, Atomic Energy Regulatory Board and Bharatiya Nabhikiya Vidyut Nigam Limited, has assigned the job to National Geophysical Research Institute and Kumar maintains as of now there is no possibility or there are any records of volcano in the region.

This comes after AERB contacted national agencies like Geological Survey of India,National Institute of Oceanography and Oil and Natural Gas Corporation of India Ltd to undertake a detailed study through expert agencies following information in Smithsonian’s Global Volanism Programme website about a reported volcano about 100-110 km from Kalpakkam.

Initial studies by National Institute of Oceanography and Oil and Natural Gas Corporation has ruled out the presence of any volcano in the region. While regional scale geophysical surveys conducted by NIO did not find any significant bathymetric anomaly that can suggest existence of such a volcano, the seismic data and wells drilled by ONGC in the vicinity did not indicate any volcanic intsrusion, AERB has said on May 31, 2013, in reply to a RTI filed by one Vetriselvan.

It also stated that as per land based geological information, Geological Survey of India has negated existence of volcanic activity at the said location but it’s offshore surveys so far neither indicate any signature of volcanic eruption in the sediments nor existence of any ephemeral island said to have formed due to the event.

Surprisingly, GSI and others have recommended for data in view of an inferred high density material intrusion of remnant magnetization based on magnetic and gravity anomalies around the said location. AERB said in reply to the RTI that based on the feedback it has asked utilities in Kalpakkam to undertake a detailed study through expert agencies and work in this regard is in progress.
