What to do if a meteor explodes over your town

SHORT ANSWERPROCEDURE · SOURCED

Look away from the flash, then get away from the windows. A big airburst's blast can arrive minutes after the light: in Chelyabinsk in 2013 it reached the city about 2:23–2:57 later, and broken glass caused most of the 1,491 injuries. Interior wall, get low, cover your head, and stay down until the booms stop. Then go out carefully and look up. If a rock comes through the roof, it's usually cool: photograph it where it landed, pick it up with clean foil or a new bag, no magnets. In the US it belongs to the landowner. Report the fireball to the American Meteor Society.246793

Why a meteor airburst is about the windows

The Chelyabinsk meteor never hit the city. On 15 February 2013 it broke apart about 30 km up, with the energy of roughly 400–500 kilotons of TNT, about 30 Hiroshima bombs.21

Light arrives instantly. The bang doesn't. The blast reached Chelyabinsk roughly 2 minutes 23 seconds to 2 minutes 57 seconds after the flash.2

When it arrived, it blew the windows in. 1,491 people sought medical help, nearly all of them hurt by indirect effects, mainly broken glass. Nobody was hit by the rock.2

Big fireballs aren't that rare. NASA's sky cameras caught one off Florida in February 2026 as bright as the full Moon, and in the first three months of 2026 the American Meteor Society logged 40 fireballs with 50 or more reports each, about double the 2018–2025 average.53

That's why the procedure looks the way it does: don't watch the window, use the silence to get away from the glass, stay down through the booms, then deal with the rock.12

There is no official meteor-specific procedure. The window steps follow general blast guidance from Ready.gov4 and what actually hurt people in Chelyabinsk12. The ownership answer is US law9.

The procedure: stuck in an elevator, what to do

  1. Look away from the flash

    Don't watch it. The Chelyabinsk fireball was momentarily brighter than the Sun. People found it painful to look at, and glancing away prevented lasting eye damage. More than 180 people reported eye pain.21

  2. Count: the blast is coming

    Light arrives instantly; the shock wave travels at the speed of sound. Chelyabinsk burst about 30 km up, and the blast reached the city roughly 2:23 to 2:57 after the flash. That gap is your time.2

  3. Get away from the glass

    Move to an interior wall or room, away from windows. Get low and cover your head. Ready.gov's blast guidance: if you have warning, take cover from the blast behind anything that might offer protection. Broken window glass caused most of the 1,491 injuries in 2013.42

  4. Stay down through the booms

    Big fireballs break into pieces, and the pieces can make their own bangs. In Chelyabinsk, sharp sounds heard after the main shock wave pointed to the fragmentation. One boom is not the all-clear.1

  5. Go out slowly and look up

    Give it a few minutes after the last boom. Cracked glass can keep falling off buildings, so look up before you step under anything. In Chelyabinsk alone, 3,613 apartment buildings had shattered and broken glass.1

  6. If a rock comes in, leave it

    It won't burn the house down. Meteorites usually land cool: the hot outside burns off on the way down. At Colby, Wisconsin, on 4 July 1917, one was so cold that frost formed on it after it was dug out. No bucket of water.6

  7. Photo first, then foil or a clean bag. No magnets.

    Photograph it where it landed. Pick it up with clean foil or a new bag, not bare hands. Never test it with a magnet: hand magnets usually erase a meteorite's magnetic record.78

  8. Check whose land it is

    In the US, a meteorite belongs to the owner of the land it falls on: Goddard v. Winchell, Iowa Supreme Court, 1892. Renting? It's your landlord's.910

  9. Report the fireball

    File a report with the American Meteor Society: the time, where you were, the direction it moved, what you heard. Reports and videos from many witnesses let scientists trace the path and search for the rest. Don't sell it tonight.311

Myths vs facts

  • MYTHA meteorite lands red-hot.

    FACTUsually it lands cool. The hot outside burns off on the way down. At Colby, Wisconsin, in July 1917, frost formed on one after it was dug out.6

  • MYTHOne boom means it's over.

    FACTBig fireballs break up, and the pieces can make their own booms. In Chelyabinsk, sharp sounds after the main shock wave pointed to the fragmentation. Wait a few minutes, then look up before you go out.1

  • MYTHIt's just a light show. Watch it.

    FACTThe Chelyabinsk flash was momentarily brighter than the Sun: more than 180 people reported eye pain and 20 reported sunburn-like UV burns. Minutes later the blast blew the windows in, and glass caused most of the 1,491 injuries. The rock hit nobody.21

  • MYTHTest it with a fridge magnet.

    FACTHand magnets usually erase a meteorite's magnetic memory. A 2025 review says magnets and other stray fields have wiped the record of more than 60% of meteorites in collections.78

  • MYTHFinders keepers.

    FACTIn the US, a meteorite belongs to the owner of the land it falls on (Goddard v. Winchell, Iowa, 1892). Ann Hodges' landlady sued for the meteorite that hit her in 1954.910

EXPERTS DISAGREE

Where the guidance runs out

  • An official meteor procedure

    There isn't one. The closest official advice is Ready.gov's guidance for a blast you have warning of, written for nuclear explosions: take cover behind anything that might offer protection, and if you're outside, lie face down. The same page says to get inside and away from windows.4

  • How far away is safe

    No set distance. Directly under the Chelyabinsk fireball the shock wave knocked people off their feet; modeled damage reached about 120 km from the track. In the direction of flight it only shook buildings.1

  • Magnet tests

    Meteorite hunters have long used magnets to identify finds. MIT researchers and a 2025 review say the same magnets erase the magnetic record.78

  • Who owns it

    In the US, an 1892 Iowa Supreme Court ruling gives it to the landowner. The Hodges case settled out of court before a judge ruled. Outside the US, local law applies; this sheet doesn't cover it.910

Two of these are physics. Two are paperwork. Do the physics first: glass, wall, down.

REAL CASE · NOT STAGEDCALDER CO.

One real case

On 15 February 2013, at about 9:20 in the morning, an asteroid about 20 meters across broke apart about 30 km above Russia's Chelyabinsk region, with roughly 400–500 kilotons of energy.12 People found the flash painful to look at.1 The blast reached the city roughly two and a half minutes later, blew in windows across six cities and damaged more than 7,200 buildings.2 1,491 people sought medical help, nearly all hurt by indirect effects, mainly broken glass; nobody was hit by the rock.2 Teacher Yulia Karbysheva saw the flash, moved her class away from the windows into duck and cover, and was badly cut by the glass herself when the blast arrived.2 The dust from the burst circled the Northern Hemisphere in four days.12

Questions people search

What should you do if a meteor explodes overhead?

Look away from the flash and get away from windows. A big airburst's shock wave can arrive minutes after the light: in Chelyabinsk in 2013 it reached the city roughly 2:23 to 2:57 after the flash. Move to an interior wall, get low, cover your head, and stay there until the booms stop. Then go out carefully and look up for falling glass. There is no official meteor-specific procedure; this follows general blast guidance and what actually hurt people in Chelyabinsk.

Is a meteorite hot when it lands?

Usually not. The hot outside burns off on the way down and the inside is still cold from space. A meteorite that fell at Colby, Wisconsin, on 4 July 1917 was so cold that frost formed on it after it was dug out.

Who owns a meteorite that lands on your property?

In the US, the landowner. In Goddard v. Winchell (1892), the Iowa Supreme Court held that a meteorite that falls on land is the property of the owner of that land. If you rent, it's your landlord's. In 1954 Ann Hodges' landlady sued for the meteorite that hit her; the case settled out of court. Other countries have their own rules.

How long after a fireball flash does the boom arrive?

It depends on how high and how far away it bursts. Light arrives instantly; sound is slow. The Chelyabinsk meteor burst about 30 km up, and its blast reached the city roughly 2 minutes 23 seconds to 2 minutes 57 seconds after the flash. In the first three months of 2026, 33 of the 40 most-reported fireballs in American Meteor Society data came with sonic booms.

How do you report a fireball?

Use the American Meteor Society's online fireball report at amsmeteors.org. Note the time, where you were, the direction it moved, how bright it was and what you heard. Reports and videos from many witnesses let scientists work out the path and where pieces may have landed.

How many people were hurt by the Chelyabinsk meteor?

1,491 people sought medical help, nearly all of them hurt by indirect effects, mainly glass from windows blown in by the shock wave. Nobody was hit by the meteorite. More than 7,200 buildings were damaged.
