Source huge explosion that shook the citizens of Bone District, Sinjai District, Wajo District in South Sulawesi Province, until Kolaka City in Southeast Sulawesi Province, Thursday (8/10) finally revealed by LAPAN Indonesia (The Institute of National Aeronautics and Space).

Astronomers from LAPAN, Dr Thomas Djamaluddin, in Jakarta, Monday (27/10), mentioned, the source of the explosion is the astronomy effect of falling meteorites objects 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).

Small meteor and termed Bone Meteor have diameter of about 10 square meters. While the magnitude meteors under 25 square meters termed an unidentified 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 12 space stations.

Blast analysis showed that the explosive force of about 50 kilotons of TNT (Trinitrotoluene). Explosion signals also reach stratosphere at 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 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).

LAPAN findings reported after receiving official confirmation, almost three weeks after the incident.

Thomas mentioned, the results of identification of an international monitoring system to ban nuclear testing from 11 monitoring stations in the world, has detected a large explosion that centered around 4.5 south latitude 120 east longitude, around 11:00 WITA (Indonesia Centre Time) 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 distribution estimatedof meteoroids-asteroids in the space near Earth, objects like that have probably fallen on the earth every two to 12 years.

This LAPAN official information answered some speculations that emerged about about a horrendous explosion triggers. Some witnesses claimed to had seen the object emits fire and smoke in the air.

However, information circulating maze, most thought the explosion was an explosion of Sukhoi Jet (Sonic Boom) who is doing the exercise from his headquarters in the 11th Air Squadron, Sultan Hasanuddin Airbase, Makassar City.

While BMKG IV Makassar (Meteorology, Climatology and Geophysics Agency) had claimed to have been a small earthquake of 1.9 on the Richter scale (SR) on the surface at the border of Bone District and Wajo District, 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 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 planes of the Indonesian Air Force.

Commander of Sultan Hasanuddin Airbase, Ida Bagus Putu Dunia said two Sukhois in exercise flying at an altitude of 10 to 30 thousand feet on the air. "But speed is not up to exceed the speed of sound," he said when reporters confirmed, a day after the incident.


Big explosion could make peoples 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 (senior high school) fainted because the sound blast. One teacher, Abidin, had photographed plumes of smoke in the sky after the explosion with a camera phone.
