Earthquake rocked the western coast of Sumatra, yesterday. The first quake occurred at 15:38 local time (GMT+07), Wednesday (April 11th, 2012), a magnitude 8.5 on the Richter scale with epicenter 346 kilometers southwest of Simeulue Island, Aceh. The quake was followed by at least 16 aftershocks. Furthermore, at 17:43 pm, another earthquake with a strength of 8.8 on the Richter scale, centered at 483 kilometers from Simeulue. The quake was followed by 11 aftershocks. The epicenter is on at 2:31 North Latitude, 92.67 East Longitude, or about 146 Southwestern Simeulue in Aceh with a depth of approximately 10 kilometers. This earthquake was also felt to Singapore, Malaysia, India, and Thailand.
The Indonoesian agency of Meteorology, Climatology, and Geophysics (BMKG) also issued a tsunami warning threat. At 19:45, a new tsunami warning is terminated. Tsunami warning issued for 27 countries - region bordering the Indian ocean. Well, judging by the earthquake, it is actually quite a large force. With 8.5 on the Richter scale and 8.8 on the Richter scale followed, a large tsunami could happen. However, although hit several areas, namely Meulaboh, Sabang and Lahewa, it turns out the tsunami is a small tsunami - very small tsunami.
Why? Head of Data Center for Information and Public Relations of the National Disaster Sutopo Purwo Nugroho explained that the reason only a small tsunami related to the location of the epicenter and fault movement. The epicenter occurred outside the subduction zone.
Subduction zones are zones where two plates meeting. Known, the first earthquake and numerous aftershocks that occurred centered in the western of subduction zone, away from the mainland island of Sumatra. The quake was different with the earthquake in Aceh in 2004. If the epicenter was outside of subduction zones, tsunami potential stay there, but smaller.
Based on the monitoring of BMKG, the tsunami that occurred just as high as 80 centimeters in Meulaboh at 17:04 pm and 6 cm in Sabang at 17.00 pm. Meanwhile, the monitoring of Bakosurtanal is also not much different. In Meulaboh, only 1.02 meter high while in Lahewa (North Nias) is only 1 meter.

A rare opportunity to see the two most luminous planets, Venus and Jupiter, appear side by side in the night sky will occur for two consecutive days, the astronomers said.
On a clear night sky from March 12 to 14, sky observers could reach out and see the two planets were in close distance, about three degrees, despite the fact that their distance apart in space.
Venus will be much brighter than Jupiter as it gets twice as much light from the Sun and 50 times more intense of the sun that shines in Jupiter, according to Sky & Telescope magazine.
Venus is also seven times closer to Earth than Jupiter - the largest of the two planets, and probably will appear two times larger than Venus.
After March 14, Jupiter will not look down until after sunset in mid-April.
Moon will appear in 25 and March 26, with a sickle shape and close to the position of Jupiter in the first night, especially in North America, and Venus in the second night.
To see a live picture of the two planets were captured by the telescope Slooh, you can go to the site http://events.slooh.com

I'm very pleased with anything related to action or military - looks really great and cool. I had aspired to become a pilot of fighter jet F-16;-)
It feels very happy if I could help keeping security of the country, despite the fact that war is a bad thing. however Life is too precious to be eliminated. Therefore, I prefer to see or read the heroic actions of the great and brave soldiers. One that I read today is the news of release of hostages in Somalia. Here the news.
Nine dead, hostages saved:
After Taking out Osama bin Laden, SEAL Team 6 Does It Again
First they took out Osama bin Laden. Now the US Navy SEALs have earned their "special forces" designation once again by conducting a daring, pinpoint rescue of two aid workers held hostage for three months in Somalia.
US officials confirmed it was a Navy SEAL team that carried out the pre-dawn raid, but the Pentagon, citing "operation security reasons," would not confirm US media reports that it was SEAL Team 6, the same unit which got Al-Qaeda leader bin Laden deep inside Pakistan last May.
American Jessica Buchanan and Dane Poul Thisted, who both worked for the Danish Refugee Council Demining Group, were rescued unharmed after helicopter-borne US commandos landed in scrubland in central Somalia early Wednesday local time, according to a local Somali official.
They killed all nine of them, the US military said. US Defence Secretary Leon Panetta said no US troops had been wounded or killed in the operation, which was personally authorized by President Barack Obama.
The SEALs -- an acronym of "Sea, Air, Land" -- specialise in reconnaissance and sea-borne assaults, often on vessels. They count some 2300 highly specialised operatives among their ranks, and their raids mostly involve participation of two teams totaling nearly 30 commandos.
For a decade, they have been putting their elite training to use on the battlefields of Iraq and Afghanistan, as have their US Army counterparts in Delta Force and the Green Berets.
Team 6 is the elite of the elite, and their missions are classified. While its shining moment was the spectacular bin Laden triumph, Team 6 is cloaked in secrecy, and its activities are almost never officially acknowledged.
According to the GlobalSecurity website, SEAL Team 6 is said to have been deployed for a possible -- but never attempted -- rescue of the Achille Lauro cruise ship from hijackers in 1985, and helped free the American captain of the container ship Maersk Alabama amid a 2009 standoff with pirates off Somalia.
According to US media, the elite fighters are also believed to have been involved in the mission to rescue Scottish aid worker Linda Norgrove in Afghanistan after she was kidnapped by members of the Taliban in 2010. Norgrove died in the operation.
Despite the stellar successes of the past year, the SEALs have also known tragedy during the same period. Seventeen US Navy SEALs, mostly from Team 6, were among 38 people killed last August when the Taliban shot down the Chinook helicopter that was transporting the US personnel, in the deadliest incident for US and NATO forces since the war in Afghanistan began in 2001.
The Team 6 moniker had been chosen by the unit's founder, Richard Marcinko, who wrote in his book "Rogue Warrior" that he wanted to trick other nations, notably the Soviet Union, into believing that the United States had more special operations teams than it actually had.
In the 1980s it had some 90 members, but its size swelled to nearly 300 after the 9/11 attacks of 2001.
While the name Team 6 continues to be used, it has not been the official designation since 1987. The unit was subsequently renamed DEVGRU, the United States Naval Special Warfare Development Group.
