Calcutta/New Delhi, Apr 11 (PTI): Calcutta and its neighbourhood were rocked by tremors of the earthquake that rocked waters off Indonesia’s coast on Wednesday. A large number of people rushed out of offices in Park Street and downtown BBD Bagh area here as windows and doors rattled.

According to reports, some buildings on Park Street developed cracks. Metro Rail services in the city were suspended from 2:42 p.m and passengers were asked to vacate stations.

Indian Tsunami Early Warning Centre issued a tsunami warning for Nicobar islands and alerted the coastal regions of Tamil Nadu and Andhra Pradesh after the earthquake, of 8.9 Richter magnitude, hit waters off the western coast of northern Sumatra.

“We have issued a tsunami warning for Nicobar Islands,” Shailesh Nayak, Secretary Ministry of Earth Sciences told PTI.

The projections issued by the ITEWC showed the tidal waves triggered by the quake hitting parts of Nicobar, Komatra and Katchal minutes after it struck the region at 14:08 IST.

The ITEWC also issued an alert for coastal Tamil Nadu, Andhra Pradesh and the Andaman Islands forecasting the arrival time of the first wave.

For Tamil Nadu, the first wave was expected to reach the coastal regions at around 4:33 p.m.

Strong tremors were felt in Chennai and some other nearby areas. People in multi storeyed apartments and those working in high rise buildings rushed out to open areas.

The Pacific Tsunami Warning Center in Hawaii said a tsunami watch was in effect for Indonesia, India, Sri Lanka, Australia, Myanmar, Thailand, the Maldives and other Indian Ocean islands, Malaysia, Pakistan, Somalia, Oman, Iran, Bangladesh, Kenya, South Africa and Singapore.

A tsunami watch means there is the potential for a tsunami, not that one is imminent.

The US Geological Survey said the powerful quake was centered 33 kilometers beneath the ocean floor.

A giant 9.1-magnitude quake off the country on Dec. 26, 2004 triggered a tsunami in the Indian Ocean that killed 2,30,000 people, nearly three quarter of them in Aceh.
