PANAJI: Two houses in Sanguem town have developed cracks due to the tremors felt in a 15-km belt on January 6 and 7, 2011, but the official inquiry has not yielded any other conclusive evidence.

“We have found that two houses were damaged during the tremors,” a source said. However, no other details were available, though sources said the inquiry did not come up with any other conclusion about the baffling tremors, which did not show on record at the Panaji Met department office.

Residents have denied that there was a blast, but attributed the tremors to mining operations in the area.

On the other hand, geologists spoke about the need to institute a seismological study to ascertain the cause and nature of the tremors, which drove some residents out of their houses.

“The extraction of huge quantities of ore may have caused an imbalance and induced seismic activity,” a geologist said. Agreed former senior geologist of mines department, Suresh Mahambre, “A geo technical study will help the probe into the incident of tremors in Sanguem.”

Antonio Mascarenhas, an NIO scientist said that at this stage, any analysis could be only speculative. “A seismological study is needed to get to the bottom of the cause of the tremors,” he said.

Mascarenhas said that mining in the area may have induced localized tremors, but if they occur only 50 m below and there are layers of soft rocks, the waves may die down and miss the seismograph…..
