New Delhi - Indian authorities issued a tsunami alert for its Andaman and Nicobar islands after a powerful earthquake jolted parts of Indonesia's Java and Sumatra islands on Wednesday. An official at the centre monitoring an early tsunami warning system in the southern Indian city of Hyderabad said there was no warning for mainland India so far.
So Andaman and Nicobar alert was precautionary in nature, he said.
"We will have to wait for an hour ... we are monitoring the changes," SK Nair of the Indian National Centre for Ocean Information Services told NDTV television channel.
The federal Home Ministry has asked officials along south-eastern coastal areas to remain alert.
The Indian Ocean tsunami of December 26, 2004 killed more than 12,000 in India, largely in the Andaman and Nicobar islands and along India's western coast, and inflicted damage and losses of about a billion dollars.
