INDONESIA EARTHQUAKE 2004

Jakarta (ANTARA) – The earthquake in Aceh in 2004 and 2012 differ greatly because eight years ago the location of earthquakes along the subduction zone meeting of the Eurasian plate and Indo-Australia, now located in the Indo-Australian plate, said tsunami expert Doctor Subandono Diposaptono.

 

“Unlike a lot, had the earthquake occurred at the meeting of the Eurasian plate and Indo-Australia, is now happening in the Indo-Australian plate, or about 175 miles farther south,” said Subandono who is also the Director of Marine and Coastal Spatial and Small Islands Ministry of Marine and Fisheries in Jakarta on Wednesday night.

 

Thus the Aceh earthquake that happened this time is an intraplate earthquake, rather than as interplate earthquake measuring 9.1 on the Richter scale Aceh on December 26, 2004. Intraplate earthquakes do not cause a large tsunami as interplate earthquakes in the subduction zone.

 

“The earthquake in Aceh in 2004 led to the edge of the Indo-Australia plate springs upward along the 1,300 km perpendicular to the subduction zone where the Indian Ocean plate under the Eurasian plate infiltrate (megathrust), from the Andaman and Simeulue to make low tide and then slammed into the mainland, “he said.

 

Earthquake this time, he said, only causes a horizontal movement causes vibrations and ripples in the ocean waves. Even if there are at most high tsunami is only 10-20 cm height only, or at least no more than three feet.

 

Subandono also recalled the importance of spatial plans form the basis of development, particularly in the area of ??the earthquake and tsunami pontensial, so it is expected to minimize the risk of disaster.

 

“Unfortunately when we’re up to the most beautiful city, but since the tsunami comes again, and again the city was destroyed, then we have to build it again,” he said.

 

He cited Japan’s quake-hit SR 9 in March 2011 and caused a tsunami up to 10 meters and killed thousands of victims. However, a year after it has been no reconstruction effort since after all the new redevelopment plan in accordance with the spatial-based disaster mitigation is ripe.

 

Spatial plans, he said, is more important than the construction of sea walls or coastal forest is less effective in minimizing the risk of disaster.
