An asteroid about twenty metres across enters the atmosphere at more than 60,000 km/h and explodes some thirty kilometres up, releasing about 500 kilotons, some thirty times the energy of the Hiroshima bomb.

Consequences

Human consequences

About 1,500 injured, mostly by broken windows: many had gone to the windows to look at the flash, brighter than the Sun.

Environmental consequences

A fragment of about 600 kg is recovered from the bottom of Lake Chebarkul. The dust plume circles the Northern Hemisphere in the stratosphere.

Economic consequences

About 7,000 buildings damaged in six towns; thousands of windows to replace in the middle of winter.

Political consequences

Filmed by hundreds of dashcams, the event gives new impetus to near-Earth asteroid detection and to an international warning network under UN auspices.
