PORT BLAIR(India), July 24: India’s Andaman and Nicobar islands, devastated by last year’s tsunami, were shaken by a strong quake on Sunday but officials said there was no danger of new killer waves hitting the Indian Ocean archipelago.

Thailand exercised caution and declared a tsunami alert but cancelled it less than 90 minutes later, while Indian officials said there was no danger of a huge wave like the one that hit last December.

“There is no tsunami warning from the Indian side,” Indian Science and Technology Ministry spokesman Sitanshu Kar told Reuters in New Delhi.

“The government is asking people to remain calm. The essential precondition for a tsunami is that the earthquake should be of 7.5 magnitude and this is below it.”

Sunday’s earthquake came seven months after the Dec. 26 tsunami, triggered by a 9.15 magnitude earthquake. Some 227,000 are dead or missing after the December tsunami.

India’s Science and Technology Minister Kapil Sibal also dismissed talk of a tsunami.

“Any talk of a tsunami as of now should not be taken heed of,” Mr Sibal told Indian television channels. “It has been two hours since the earthquake. If the tsunami was coming, it would have come by now.”

The quake hit the area off India’s eastern coast at 1542 GMT measuring 7.0, according to the US Geological Survey which initially urged authorities near its epicentre to be aware of the risk of local tsunamis.

But it also said on its Web site they could assume the danger had passed if no tsunamis were seen within an hour of the tremor, which hit at a depth of 10 km. All over the Andaman islands, people ran from their homes and gathered in open places. —Reuters
