The capital of Andaman and Nicobar islands, Port Blair, has shifted by over one metre after the killer earthquake and Tsunami of December 26, a preliminary survey data has revealed.
A team of surveyors from the Survey of India, compiling scientific readings from across the Andaman and Nicobar islands, has discovered that its Port Blair control point had shifted towards the south-eastern side by 1.15 metres from its earlier position.
"The sea has also recorded a not-so-significant drop of 25 cm from its earlier level at the Port Blair control point, which leads us to infer that there could be some subsidence also," Surveyor General of India Prithvis Nag told PTI on Saturday.
However, the mean sea level has also increased by 1.5 m post-tsunami, he said.
A seven-member team of the survey body studying the latitude, longitude and height at 20 of its control points in the islands would compile the final data, which would be released at an international conference on disaster management on January 21, he said.
