Kementerian Darurat melaporkan bahwa 20.000 pekerja penyelamatan yang beroperasi di wilayah tersebut. Tiga pesawat dikerahkan untuk daerah survei dan menemukan lokasi lain dampak yang mungkin timbul.

Para saksi mata mengatakan ledakan itu begitu keras bahwa itu tampak seperti gempa bumi dan guntur telah menyerang pada saat yang sama, dan bahwa ada jejak besar asap di langit. Lain melaporkan melihat benda terbakar jatuh ke bumi.

Polisi di wilayah Chelyabinsk dilaporkan pada siaga tinggi, dan 'Operasi Benteng' telah dimulai untuk melindungi infrastruktur penting.

Video and Photos Meteorite crash in Russia A series of explosions in the skies of Russia’s Urals region, reportedly caused by a meteorite shower, has sparked panic in three major cities. Witnesses said that houses shuddered, windows were blown out and cellphones have stopped working. According to unconfirmed reports, the meteorite was intercepted by an air defense unit at the Urzhumka settlement near Chelyabinsk. A missile salvo reportedly blew the meteorite to pieces at an altitude of 20 kilometers.

A bright flash was seen in the Chelyabinsk, Tyumen and Sverdlovsk regions, Russia’s Republic of Bashkiria and in northern Kazakhstan.

Up to 150 people sought medical attention as a result of the incident, according to the Russian Interior Ministry. No serious injuries have been reported, with most of the injuries caused by broken glass and minor concussions.

Lifenews tabloid said that at least one piece of the fallen object caused damage on the ground in Chelyabinsk. According to preliminary reports, it crashed into a wall near a zinc factory, disrupting the city's Internet and mobile service.

The Emergency Ministry reported that 20,000 rescue workers are operating in the region. Three aircraft were deployed to survey the area and locate other possible impact locations.

Witnesses said the explosion was so loud that it seemed like an earthquake and thunder had struck at the same time, and that there were huge trails of smoke across the sky. Others reported seeing burning objects fall to earth.

Police in the Chelyabinsk region are reportedly on high alert, and have begun ‘Operation Fortress’ in order to protect vital infrastructure.

Office buildings in downtown Chelyabinsk are being evacuated. Injuries were reported at one of the city’s secondary schools, supposedly from smashed windows. 

An emergency message published on the website of the Chelyabinsk regional authority urged residents to pick up their children from school and remain at home if possible.

Those in Chelyabinsk who had their windows smashed are scrambling to cover the openings with anything available – the temperature in the city is currently -6°C.

Background radiation levels in Chelyabinsk remain unchanged, the Emergency Ministry reported.

The regional Emergency Ministry said the phenomenon was a meteorite shower, but locals have speculated that it was a military fighter jet crash or a missile explosion.

“According to preliminary data, the flashes seen over the Urals were caused by [a] meteorite shower," the Emergency Ministry told Itar-Tass news agency.

The ministry also said that no local power stations or civil aircraft were damaged by the meteorite shower, and that“all flights proceed according to schedule.”

Residents of the town of Emanzhilinsk, some 50 kilometers from Chelyabinsk, said they saw a flying object that suddenly burst into flames, broke apart and fell to earth, and that a black cloud had been seen hanging above the town. Witnesses in Chelyabinsk said the city’s air smells like gunpowder.

Residents across the Urals region were informed about the incident through a cellphone text message from the regional Emergency Ministry.

Many locals reported that the explosion rattled their houses and smashed windows. 

Evgeniya Gabun wrote on Twitter.

“My window smashed, I am all shaking! Everybody says that a plane crashed,” Twitter user Katya Grechannikova reported.

“My windows were not smashed, but I first thought that my house is being dismantled, then I thought it was a UFO, and my eventual thought was an earthquake,” Bukreeva Olga wrote on Twitter.

The Mayak nuclear complex near the town of Ozersk was not affected by the incident, according to reports. Mayak, one of the world’s biggest nuclear facilities that used to house plutonium production reactors and a reprocessing plant, is located 72 kilometers northwest of Chelyabinsk.

It is believed that the incident may be connected to asteroid 2012 DA14, which measures 45 to 95 meters in diameter and will be passing by Earth tonight at around 19:25 GMT at the record close range of 27,000 kilometers.

The incident in Chelyabinsk bears a strong resemblance to the 1908 Tunguska event – an exceptionally powerful explosion in Siberia believed to have been caused by a fragment of a comet or meteor.

According to estimates, the energy of the Tunguska blast may have been as high as 50 megatons of TNT, equal to a nuclear explosion. Some 80 million trees were leveled over a 2,000-square-kilometer area. The Tunguska blast remains one of the most mysterious events in history, prompting a wide array of hypotheses on its cause, including a black hole passing through Earth and the wreck of an alien spacecraft.

It is believed that if the Tunguska event had happened 4 hours later, due to the rotation of the Earth it would have completely destroyed the city of Vyborg and significantly damaged St. Petersburg.   

When a similar, though less powerful, unexplained explosion happened in Brazil in 1930, it was named the ‘Brazilian Tunguska.’ The Tunguska event also prompted debate and research into preventing or mitigating asteroid impacts.
