"We are planning to install seismographs in two to three places in the Andaman Islands. By the end of this year, the work should be complete," GSI Director General A Sundaramoorthy said.
GSI already has seismographs in Maharashtra (Nagpur), Madhya Pradesh (Jabalpur), Sikkim (near Gangtok) and Tripura (Agartala).
Asked if there were plans to install seismographs in South India, he said, "South India below the Vindhyas exhibit lesser seismic activity compared to the North and Andaman and Nicobar Islands. So there is no need for it at present."
