The Central government on Thursday asked the Andaman and Nicobar Islands administration to monitor the situation in view of a fresh earthquake, measuring 7.8 on the Richter scale, in Indonesia.
The island authorities have been asked to 'keep watch' on the situation, Home Ministry spokesman said, adding that no alert has been issued.
A tsunami alert was issued on Wednesday to Andaman and Nicobar islands, after a powerful earthquake of 7.9 magnitude hit Indonesia last evening, but withdrawn after three hours when it appeared that there was no imminent threat.
The Home Ministry is constantly taking stock of the situation, the spokesman said.
The Pacific Tsunami Warning Center in Hawaii warned that the latest earthquake had the potential to generate destructive waves within 1,000 kilometers of the epicenter.
