The shockwave was “heard” halfway around the world.

The shock wave from Friday’s (Feb. 15) meteor explosion above Russia sent subsonic waves through the atmosphere halfway around the world.

Up to 11 sensors in Greenland, Africa, Russia’s Kamchatka Peninsula and other far-flung regions detected the Russian meteor blast’s infrasound, or low-frequency sound waves. The sensors are part of the global network of 60 infrasound stations maintained by the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO).

Space rocks are cool.  Seriously.  There’s something metal about chunks of rock and iron hurtling through space at thousands of miles an hour slamming into the atmosphere and bursting into flames before exploding, melting, or smashing into the earth.

The blast from the meteor was 30 times that of Hiroshima.

The object is estimated to have been about 17 m across with a mass of 7,000–10,000 tonnes when it hit atmosphere. It exploded with a force of nearly 500 kilotons of TNT –- some 30 times the energy released by the Hiroshima atomic bomb — around 15 to 20 km above the ground.

I’d say we got lucky.  Most of the injuries were minor, and the property damage estimates are very low.  If it had been 25 m across, it would have had the same power as the quake which caused the Fukushima tsunami.

Yeah, that is really cool. But it is a time lapse video: my French is very bad, but I read from the comments that the playing of the video is accelerated witch a factor 50. That fits more or less with the technical info: recorded from 20:01 till 20:16, and the video is 16 seconds.

Some people think that astronomy is far removed from their daily lives.  But then when it lands in your neighborhood, then look out people!

The ‘ol shooting gallery still has billions of shots left.  downer

The concussion was impressive, any closer or bigger and. . .

If it had been over a densely populated area….or come in more directly, instead of the oblique hit Russia took, they would have been screwed.
