Still unconfirmed, but the tsunami will most likely not hit India because, the Sumatra earthquake moved horizontally, not vertically. However, the Chennai port has been shut and fishermen have been asked to move to higher places. No waves noticed so far in Andaman and Nicobar Islands, which means that the tsunami is virtually ruled out, says NDMA vice president Sasidhra Reddy.
