Earthquake in Indonesia #PrayForSumatera Magnitude 8.9 Tremors in India after huge Indonesia earthquake; tsunami alert across Indian Ocean



New Delhi:  A tsunami warning has been issued for the entire Indian Ocean after an earthquake measuring  8.7 on the Richter scale hit Indonesia a little after 2 pm.  Officials in the Andaman and Nicobar Islands are preparing for evacuation procedures, though they stress that there has been no tsunami sighting so far.  Three-six metre high waves were expected to hit the Nicobar Islands at 2.40 pm.  On the beaches at Chennai, policemen used megaphones to ask people to leave. 

The quake was felt in Singapore, Thailand and India. High-rise apartments and offices on Malaysia's west coast shook for at least a minute.

In India, tremors were reported  in Mumbai, Kolkata,  Bangalore and the southern part of Chennai.  The tremors lasted for a few seconds.  In Bhubaneshwar, people were seen running out of their homes and offices.  No damage has been reported so far.

NDTV viewer AG Kalidass emailed from Bangalore to say, "We were feeling our building shaking." Another viewer Shyam Agarwal writes, "I am from Kolkata. Just now a few minutes back heavy stroke of earthquake has been observed here."

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

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  in 13 Indian Ocean countries, including Thailand, Sri Lanka and India.

Huge quake strikes off Indonesia, tsunami warning issued


JAKARTA | Wed Apr 11, 2012 5:56am EDT
(Reuters) - An 8.7 magnitude earthquake struck off the coast of Indonesia on Wednesday, sending residents around the region dashing out of their homes and offices in fear.
The Pacific Tsunami Warning Center said a tsunami watch was in effect for the entire Indian Ocean and individual countries, including Thailand, Indonesia, Sri Lanka and India, issued tsunami warnings.
People near the coast in six Thai provinces were ordered to higher ground.
The quake struck 308 miles southwest of the city of Banda Aceh, on the northern tip of Indonesia's Sumatra island, at a depth of 20.5 miles, the U.S. Geological survey said.
Indonesia's disaster management agency said power was down in Aceh province and people were gathering on high ground as sirens warned of the danger.
"The electricity is down, there are traffic jams to access higher ground. Sirens and Koran recitals from mosques are everywhere," said Sutopo, spokesman for the agency.
The quake was felt as far away as the Thai capital, Bangkok, and in southern India, residents said.
Hundreds of office workers in the Indian city of Bangalore left their buildings while the Indian port of Chennai closed down because of the danger of a tsunami, the port said.
The quake was in roughly in the same area as a December 26, 2004, quake of 9.1 magnitude, which sent huge tsunami waves crashing into Sumatra, where 170,000 people were killed, and across the Indian Ocean.
In all, the 2004 tsunami killed about 230,000 people in 13 Indian Ocean countries, including Thailand, Sri Lanka and India.
The 2004 quake was at a depth of 18 miles along a fault line running under the Indian Ocean, off western Indonesia and up into the Bay of Bengal.
One expert told the BBC the Wednesday quake as a "strike-slip" fault, meaning a more horizontal shift of the ground under the sea as opposed to a sudden vertical shift, and less risk of a large displacement of water triggering a tsunami.
The quake was also felt in Sri Lanka, where office workers in the capital, Colombo, fled their offices, and the southern Thai holiday island of Phuket, both of which were hit hard by the 2004 tsunami.
In Bangladesh, where two tremors were felt, authorities said there appeared to be no threat of a tsunami. Australia also said there was no threat of a tsunami there.

STORY HIGHLIGHTS
  • NEW: Residents in Banda Aceh are moving to higher ground
  • A tsunami watch has been issued for the Indian Ocean
  • The 8.7 magnitude quake took place off the coast of Aceh
  • The Indonesian province was devastated by a tsunami in 2004
(CNN) -- A massive earthquake struck off the coast of the Indonesian island of Sumatra on Wednesday, triggering a tsunami alert for the Indian Ocean.
The quake struck about 430 kilometers from Banda Aceh, the capital of Indonesia's Aceh province, and had a magnitude of 8.7, the U.S. Geological Survey said. It took place at a depth of 33 kilometers.
The Pacific Tsunami Warning Center said it had issued a tsunami watch for the entire Indian Ocean, and the Indonesian Meteorology, Climatology and Geophysics Agency said it had put up a tsunami warning.
The power has gone out in Banda Aceh and residents are moving to higher ground, said Sutopo Purwo Nugroho, a spokesman for the Indonesian National Disaster Management Agency.
The extent of the damage is still being assessed.
In 2004, a 9.1-magnitude underwater earthquake struck off the coast of Sumatra, triggering a tsunami that killed more than 200,000 people in 14 countries. Aceh was one of the worse affected areas.
The tsunami, which washed away entire communities, caused nearly $10 billion in damage and more casualties than any other tsunami in history, according to the United Nations.
Indonesia is on the so-called Ring of Fire, an arc of fault lines circling the Pacific Basin that is prone to frequent earthquakes and volcanic eruptions.



8.7-magnitude earthquake strikes off Indonesia, triggering tsunami watch

Published April 11, 2012

A tsunami watch was issued for countries across the Indian Ocean after a large earthquake hit waters off Indonesia on Wednesday, triggering widespread panic as residents along coastlines fled to high ground in cars and on the backs of motorcycles.
Some were crying. Others screamed "God as great" as they poured from their homes.
The U.S. Geological Survey said the 8.7-magnitude quake was centered 20 miles beneath the ocean floor around 269 miles from Aceh's provincial capital.
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.
Said, an official at Indonesia's Meteorology and Geophysics Agency who goes by only one name, said a tsunami warning has been issued for cities all along the coast of Sumatra island.
There was chaos in the streets, with fierce shaking continuing for nearly four minutes.
"I was in the shower on the fifth floor of my hotel," Timbang Pangaribuan told El Shinta radio from the city of Medan. "We all ran out. ... We're all standing outside now."
He said one guest was injured when he jumped from the window of his room.
The tremor was felt in Singapore, Thailand, Bangladesh, Malaysia and India. High-rise apartments and offices on Malaysia's west coast shook for at least a minute.
Thailand's National Disaster Warning Center issued an evacuation order to residents in six provinces along the country's west coast, including the popular tourist destinations of Phuket, Krabi and Phang-Nga.
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.

JAKARTA (AFP) - A massive earthquake struck off Indonesia's Sumatra island on Wednesday, US and Indonesian monitors reported, prompting a Indian Ocean-wide tsunami alert.
Readers of the Straits Times also reported feeling tremors in Serangoon, Raffles Place, and in eastern Singapore.
The quake's magnitude was 8.7, according to a revised measurement from the US Geological Survey, and it struck 431km off the Indonesian city of Banda Aceh.
The city was near the epicentre of a devastating 9.1-magnitude quake in 2004 that triggered a tsunami across the Indian Ocean, which killed 220,000 people, including 170,000 in Aceh.
The latest tremor was felt as far afield as Thailand and southern India.
