4.52pm: Tsunami wave of 1.06M (3.5FT) above normal sea level recorded near Meulaboh in Indonesia. Indonesia's geophysics agency has also said that they have detected a rise in sea water level in West and North Aceh of unto 0.8 meters.

4.45pm: The Indonesia geophysics agency has extended the Aceh Tsunami warning by two hours following a strong 8.1 magnitude earthquake off the coast of Sumatra. The tremors from the second quake have been felt in India as well.

4.26pm: Reports are coming in that a strong 8.1 aftershock has been reported off Sumatra Indonesian seismologists say. They have issued a fresh alert of a tsunami.Further details are awaited. Meanwhile Reuters has reported that sea water at Simeulue Island near the epicenter of the quake has been seen receding by about ten meters. USGS puts the magnitude of aftershock at 8.2; and say it struck 382 miles SSW off Banda Aceh.

4.16pm: The National Disaster Management centre has said that no waves have been noticed so far in Andaman and Nicobar and that a tsunami has been virtually ruled out according to NDMA Vice President Sasithra Reddy. However the Pacific tsunami warning centre has said that the tsunami alert for 28 countries remains in effect. Tamil Nadu and Andhra Pradesh have begun evacuating ports and beaches, and have asked fishermen not to venture out into sea. People in South Andamans have been evacuated as a precautionary measure.

Simon Boxall, from the national oceanography centre in UK, says we seem to be out of the woods with regards to tsunami and if nothing happens in the next half hour it is unlikely we will see one.

3.33pm: Indonesia's president says "no tsunami threat although we are on alert" from Aceh quake. Indonesia's disaster mitigation agency says that there is no detection of low tide that would indicate a tsunami in Aceh.

Meanwhile Bruce Pressgrave of the US Geological Survey told BBC that it was unlikely that a tsunami would be generated since this type of earthquake does not generate a column of water that could cause a tsunami.

“There’s always a hazard but with this kind of quake it reduces the risk of a tsunami,” he said.

While it was hoped that there would be no tsunami it was prudent to issue a tsunami warning given the magnitude of the earthquake, he said.

The only possibility was if the massive earthquake had resulted in an underwater landslide which in turn could cause a tsunami, Pressgrave said, adding it remained unlikely.

3.25pm: Ships anchored off the coast of Nicobar have been asked to move to high seas as a tsunami alert has been generated for 28 countries. Other preventive measures in India include the shutting of the port in Chennai, the halt of the Kolkata metro and the evacuation of beaches in certain areas. strong>IMPORTANT: It is not yet known whether a tsunami wave has been generated or not, and there is as yet, no cause for panic.

3.03pm: The Tsunami centre in Hyderabad issues notice for evacuation of beaches, and the Kolkata metro has been stopped.

The U.S. Geological Survey said Wednesday the quake was centered 20 miles (33 kilometers) beneath the ocean floor around 308 miles (495 kilometers) from the provincial capital of Banda Aceh.

Said, an official at Indonesia's Meteorology and Geophysics Agency who goes by only one name, said a tsunami warning has been issued.

Indonesia straddles a series of fault lines that makes the vast island nation prone to volcanic and seismic activity.

A giant 9.1-magnitude quake off the country on Dec. 26, 2004, triggered a tsunami in the Indian Ocean that killed 230,000 people, nearly three quarter of them in Aceh.
