Meteorology, Climatology and Geophysics Agency said an earthquake measuring 8.5 on the Richter scale is a potential tsunami. Residents panic, and still scarred by the trauma, then poured into the streets. In haste, they attempted to escape to higher ground, avoiding the possibility of tsunami.
The situation became more dramatic due to the roar of a siren call to prayer echoing chime everywhere, and power outages caused by the earthquake.

Experts from the Earth Observatory of Singapore, Professor Kerry Sieh, and Edward said there is potential for large earthquakes in the Indian Ocean Indonesia, precisely around the Mentawai. This is due to the reverse fault or megathrust in the Mentawai.
Predicted to cause a shift megathrust earthquake measuring 8.8 magnitude. Not only that, any tsunami threat endangering the West Coast around the Mentawai islands.
analyze the earthquake which occurred Wednesday, occurred outside the zone of plate subduction or collision zones. "There is no relation to the Mentawai
the Australian plate, India, there are many fractures or cracks. "Some of the north and south. In the fracture there is a move, this causes an earthquake," he said. "The difference, nothing to do with the Mentawai."
Earthquake Epicenter Data
Meteorology, Climatology and Geophysics Agency said the first time this earthquake measuring 8.9 magnitude. Epicenter of the quake occurred at coordinates 2.31 North Latitude, 92.67 East Longitude, or about 346 kilometers southwest of the district Simeleu. While the epicenter at a depth of 10 kilometers from the sea surface.
However, BMKG then update the data twice. First, a magnitude 8.5 earthquake called SR. But then, again BMKG rectify and said an earthquake measuring 8.3 magnitudes.
On the release of the first quake, BMKG also said potential tsunami earthquake. But the tsunami warning was lifted a few hours after the earthquake, or about 20:15 o'clock.

But then comes aftershocks with greater force. At around 17:43, calling BMKG 8.1 earthquake shook the power of the SR. The earthquake occurred at the epicenter of an earthquake similar to the first, this time at a depth of 24 kilometers.
Major earthquake measuring 8.5 on the Richter scale hit parts of Sumatra. Ocean earthquake centered in Indonesia was also felt in neighboring countries such as Malaysia, Thailand, and India.
