TOPOGRAPHY: A giant volcano in Sumatra

JAKARTA (Ant): The team consists of experts from the combined geological Indonesia, U.S., France and find a giant volcano under the waters west of Sumatra. Berdiameter volcano is 50 km high and 4600 meters and is located 330 km west of Bengkulu City.

The geologist is derived from the Pengkajian and Application of Technology (BPPT), Indonesia Institute of Science (LIPI), Ministry of Energy and Mineral Resources, CGGVeritas and IPG (Institut de Physique du Globe) Paris.

"Mountain fire is very large and high. In mainland India, there is no mountain, but at this Mount Jayawijaya in Papua," said Director of Technology Center for Natural Resources Inventory of Joseph Surachman BPPT in Jakarta, Thursday (28-5).

Under sea volcano in the Sunda Palung in southwest Sumatra, 330 km from Bengkulu, 5.9 km in depth with the peak in the depth of 1280 meters above sea level. Although this mountain is known to have a marker as kaldera volcano, the experts claim to know the level has not been active volcano under the sea this.

"The volcano under the sea is very dangerous if it burst," he said. Surveys using the seismic vessel Geowave Champion sophisticated property CGGVeritas is the first in the world because the streamer terpanjang, 15 km from the ship had carried out seismic surveys.

This is the purpose of the survey to know the geological structure (penetration up to 50 km) which includes Palung Sunda, akresi prism, tinggian bow outside (outer arc high), and bow front cavity (Fore arc basin) waters of Sumatra.

Since the end of the earthquake and tsunami in 2004 and the earthquake-susulan another big earthquake, there was a lot of changes in the structure of the Sumatra area of interest that many foreign researchers.

Team of experts from Indonesia, the U.S., France and then work together to map out the geological structure to better understand the source and mechanism of the earthquake triggered the tsunami in the seismic image of the (deep seismic image). U n-2
