Russian meteor: Hundreds injured as falling meteor shatters windows, damages buildings
Almost 1,000 people were injured when a meteor shot across the sky and exploded over central Russia on Friday, sending fireballs crashing to Earth, shattering windows and damaging buildings.

MOSCOW—A meteor streaked through the sky and exploded Friday over Russia’s Ural Mountains with the power of an atomic bomb, its sonic blasts shattering countless windows and injuring hundreds of people. The spectacle deeply frightened thousands, with some elderly women declaring the world was coming to an end.
The meteor — estimated to be about 10 tons — entered the Earth’s atmosphere at a hypersonic speed of at least 54,000 kph (33,000 mph) and shattered about 30-50 kilometres (18-32 miles) above the ground, the Russian Academy of Sciences said in a statement.
It released the energy of several kilotons above the Chelyabinsk region, the academy said.
Chelyabinsk health chief Marina Moskvicheva, said that 985 people in her city had asked for medical assistance. The Interfax news agency quoted her as saying 43 were hospitalized.
Amateur video broadcast on Russian television showed an object speeding across the sky about 9:20 a.m. local time, just after sunrise, leaving a thick white contrail and an intense flash.
“There was panic. People had no idea what was happening. Everyone was going around to people’s houses to check if they were OK,” said Sergey Hametov, a resident of Chelyabinsk, a city of 1 million about 1,500 kilometres east of Moscow.
“We saw a big burst of light, then went outside to see what it was and we heard a really loud thundering sound,” he told The Associated Press by telephone.
The explosions broke an estimated 100,000 square meters (more than 1 million square feet) of glass, city officials said.
The city administration said 758 people sought medical care after the explosions and most were injured by shards of glass. Athletes at a city sports arena were among those cut up by the flying glass.
It was not immediately clear if any people were struck by space fragments.
A fireball blazed across the horizon, leaving a long white trail in its wake which could be seen as far as 200 km away in Yekaterinburg, Reuters reported. Car alarms went off, windows shattered and mobile phone networks were interrupted.
“I was driving to work, it was quite dark, but it suddenly became as bright as if it was day,” Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains, told Reuters.
“I felt like I was blinded by headlights,” he said.
“I was standing at a bus stop, seeing off my girlfriend,” Andrei, a local resident who did not give his second name, told Reuters. “Then there was a flash and I saw a trail of smoke across the sky and felt a shockwave that smashed windows.”
Another Chelyabinsk resident, Valya Kazakov, said some elderly women in his neighbourhood started crying out that the world was ending.
City officials said 3,000 buildings in the city were damaged by the shock wave, including a zinc factory where part of the roof collapsed.
The Emergencies Ministry described Friday’s events as a “meteor shower in the form of fireballs” and said background radiation levels were normal, according to Reuters. It urged residents not to panic.
Chelyabinsk city authorities urged people to stay indoors unless they needed to pick up their children from schools and kindergartens. They said what sounded like a blast had been heard at an altitude of 10,000 metres.
Small pieces of space debris — usually parts of comets or asteroids — that are on a collision course with the Earth are called meteoroids. They become meteors when they enter the Earth’s atmosphere. Most meteors burn up in the atmosphere, but if they survive the frictional heating and strike the surface of the Earth they are called meteorites.
Meteors typically cause sizeable sonic booms when they enter the atmosphere because they are travelling much faster than the speed of sound. Injuries on the scale reported Friday, however, are extraordinarily rare.
The meteor hit less than a day before the asteroid 2012 DA14 is to make the closest recorded pass of an asteroid to the Earth — about 17,150 miles (28,000 kilometres). But the European Space Agency in a tweet said its experts had determined there was no connection.
More than 500 people were injured when a meteorite shot across the sky and exploded over central Russia on Friday, sending fireballs crashing to Earth, shattering windows and damaging buildings.
The meteorite streaked across the sky in the Russian city of Chelyabinsk (that would be where the letter A is on the map below), in the Ural Mountains.
Some fragments fell in a reservoir outside the town of Cherbakul, the regional governor’s office said, according to the ITAR-Tass.
A six-metre-wide crater was found in the same area, which could come from space fragments striking the ground, the news agency cited military spokesman Yaroslavl Roshchupkin as saying.
Reports conflicted on what exactly happened in the clear skies. A spokeswoman for the Emergency Ministry, Irina Rossius, told the AP there was a meteor shower, but another ministry spokeswoman, Elena Smirnikh, was quoted by the Interfax news agency as saying it was a single meteor.
Donald Yeomans, manager of the U.S. Near Earth Object Program in California, said he thought it was probably “an exploding fireball event.”
“If the reports of ground damage can be verified, it might suggest an object whose original size was several meters in extent before entering the atmosphere, fragmenting and exploding due to the unequal pressure on the leading side vs. the trailing side (it pancaked and exploded),” Yeoman said in an email.
“It is far too early to provide estimates of the energy released or provide a reliable estimate of the original size,” Yeomans added.
The site of Friday’s spectacular show is about 5,000 kilometres west of Tunguska, which in 1908 was the site of the largest recorded explosion of a space object plunging to Earth. That blast, attributed to a comet or asteroid fragment, is generally estimated to have been about 10 megatons; it levelled some 80 million trees.
The dramatic events prompted an array of reactions from prominent Russians.
Prime Minister Dmitry Medvedev, speaking at an economic forum in the Siberian city of Krasnoyarsk, said the meteor could be a symbol for the forum, showing that “not only the economy is vulnerable, but the whole planet.”
Vladimir Zhirinovsky, a nationalist leader noted for vehement statements, said “It’s not meteors falling. It’s the test of a new weapon by the Americans,” the RIA Novosti news agency reported.
Deputy Prime Minister Dmitry Rogozin said the incident showed the need for leading world powers to develop a system to intercept objects falling from space.
“At the moment, neither we nor the Americans have such technologies” to shoot down meteors or asteroids, he said, according to the Interfax news agency.
