Makassar, BERANDA - Source huge explosion that shook the citizens of Bone, Sinjai, Wajo, until Kolaka in Sulawesi Tenggara (Southeast Sulawesi), Thursday (8 / 10) and, finally officially revealed by the Institute of National Aeronautics and Space (LAPAN).
Astronomers from the Institute of Aviation and Space Agency (Lapan), Dr Thomas Djamaluddin, in Jakarta, Monday (27/10), mentioned, the source of the explosion is the effect of falling objects asrtonomi meteorites from the asteroid that exploded in the most basic layer of the earth atmospher of the Stratosphere ( 40 km from the earth) and troposphere (altitude of 10 km from the earth's surface).
Object small meteors and meteor termed this Bone diameter of about 10 square meters. While the magnitude meteors under 25 square meters Unidentified termed a meteorite.
"The explosion occurred due to atmospheric pressure causes the release of considerable energy, where the meteorite fall rate of about 20.3 km per second or 73,080 km per hour," said Thomas, who launch this identification after getting confirmation from space station 12.
Blast analysis showed that the explosive force of about 50 kilotons of TNT (Trinitrotoluene). Explosion signals also reach the high stratosphere more than 20 km.
With the power of 50 kilotons, if this explosion to the earth, the effects roughly almost four times the atomic bomb dropped on Allied troops two strategic cities of Japan, Hiroshima and Nagasaki, in 1945.
Just to illustrate, the bomb nicknamed The Little Boy Atomic Bomb (August 6, 1945), as reported by wikipedia, exploding with energy force of 15 kilotons of TNT (ÿ 6.3 x 1013 Joules).
Reporting LAPAN findings after receiving official confirmation, almost three weeks after the incident.
Thomas is also known as an astronomer was mentioned, the results of an international monitoring system indetifikasi to ban nuclear testing from 11 monitoring stations in the other world, has detected a large explosion that centered around the latitude and longitude 4.5 LS 120 BT, around 11 : 00 wita on October 8.
But most asteroids that fell did not cause damage on Earth except for its diameter reaches more than 25 square meters.
According to Thomas, based on the estimated distribution of meteoroids, asteroids in the space near Earth, such objects have probably fallen on the earth every two to 12 years.
This LAPAN official information and answer some speculation that emerged about the explosion that triggers menhebohkan. Some witnesses claimed to had seen the object emits fire and smoke in the air. However, circulating information maze, most thought the explosion was an explosion of Sukhoi jet fighter (Sonic Boom) who is doing the exercise from his headquarters in the 11th Air Squadron Sultan Airbase Hassanuddin, Makassar.
While meteorology agency Climatology and Geophysics (BMKG) IV Makassar had claimed to have been a small earthquake of 1.9 on the Richter scale (SR) on the surface at the border of Bone and Wajo, where in the region have Saddang Fault.
Other residents said the blast that could cause vibrations in the ground was caused by fish bombing carried out the local fishermen. But there are also people who have guessed that the object is a meteorite.
Supersonic jet engine explosion that created the sound reverberated like an explosion. Then accompanied by vibrations from the air waves. Waves of air that comes from pounding the body and engine thrust
Mystery of loud explosions had also associated with the practice's six military fighter plane the Air Force.
Lanud TNI Commander Sultan Hasanuddin Air Force, Air Marshal TNI First World Ida Bagus Putu said two Sukhoi aircraft flying in the exercise at an altitude of 10 to 30 thousand feet in the air. "But speed is not up to exceed the speed of sound," he said when reporters confirmed, a day after the incident.
Panic
Big explosion could make people jump out of the house and another wondered about the explosion.
The explosion also caused a deepening vibration makes people panic. Some students at SMAN 4 Watampone fainted from the sound blast.
One local teacher, Abidin, had photographed plumes of smoke in the sky after the explosion with a camera phone.
"Clumps of smoke right at the source of the explosion because previously seen a big spark," said Andi Hermanto, another eyewitness who was d Watampone SMAN 4.
Not only in school, teachers are forced to return all the students for fear that vibrations would cause an earthquake.
Panic residents very reasonable, because the sound is very loud explosion a few times and seen a puff of white smoke rising in the sky Bone. From the information compiled, just after the mysterious explosion in the village residents Pallime, Cenrana district adjoining the busy-busy sea fled to neighboring villages.
Likewise that occur in areas located near the shore as several existing village dikecamatan Riattang Tanete East, Kajuara, Sibulue, and Tonra.
Some witnesses thought that the explosion was a meteor that fell from the sky, causing a fairly loud explosion. "By Allah, I saw with my own eyes. At first I was shocked that such a flash of sun in the shadow of my clothes (white shirt), when he looked up, I look like a meteor that quickly enveloped in flames moving down after it disappeared and a cloud of smoke arose thick, "said Firdaus (29), resident of Jl Sukawati Watampone.
Meteor Issues
Issues that the four explosions that occurred in the bone caused by a kind of meteor stronger than the issues that the explosion caused by the aircraft crashed.
The reason, a member of Bone police who participated in the search for the source of the explosion because of suspected aircraft crashed a short message or a text message from her relatives in Kendari, Southeast Sulawesi.
A 10-year-old boy, son of Police named Briptu Agus Bone, also called her father for fear of seeing the fire in the sky.
Reporter who was covering the bone, get information from Briptu Agus, that her son called her crying because of fear of seeing a fire and explosion from the sky.
