Northeast under threat of 9 magnitude quake

Nearly 300 aftershocks have been recorded in the northeastern region after the massive 6.9 earthquake in Sikkim last year.

 
Gangtok: 

The northeast Indian region, especially Sikkim, is under the threat of a very powerful earthquake, scientists have revealed.

“The entire Northeastern Zone is at present facing the threat of an earthquake from the Himalayan regions, one that has the potential of being of magnitude 9,” says Professor Shankar Nath of IIT Kharagpur.

Nearly 300 aftershocks have been recorded in the northeastern region after the massive 6.9 earthquake in Sikkim last year.

Besides West Bengal and Bihar, the tremors of the quake were also felt in Nepal and Tibet, killing 40 people. Out of the victims, 19 died in Sikkim.

Some parts of Sikkim are now recommended to be upgraded to Zone V, which carries the highest risk.

“We have completed part of our Sikkim- Darjeeling project. We have recommended that parts of Sikkim including Gangtok, Mangan and Singtham be updated to Zone V from Zone IV,” Nath said.

The scientists also recommend up gradation of few areas of the Terai- Dooars region.

Months of study by the geo-scientists have revealed that the earthquakes, frequently hitting Sikkim and neighbouring areas of Bengal, have not been induced by water reservoirs.

“After the last year’s earthquake, there was a brainstorming session. We reached a conclusion that the earthquake is not reservoir induced. Therefore, hydel projects are not a threat to the area.”

Geo-scientists are of the opinion that the earthquakes have originated rather from tectonic shifts.

The state government officials say the state has 27 hydel power projects out of which four are operational.

According to Nath, the projects can be affected due to earthquakes, but the projects cannot cause earthquakes.

Sugata Hazra, Head of the School of Oceanographic studies in Jadavpur University, said the seismicity in the said regions has increased and these are not reservoir-induced earthquakes. Hence, the Sikkim and Bengal Governments are advised to revise disaster management plans.
