Russia Meteor Shock 'Went Twice Around Earth'

[dipsydoodle]

The shockwaves from the meteor which exploded over Russia in February travelled twice around the Earth, according to scientists.

More than 1,000 people were injured when the 10,000 ton object - larger than a double-decker bus - burnt up in the skies above Chelyabinsk in Siberia.

The tremors from the meteor were recorded at 20 'infrasonic' monitoring stations, which are designed to detect nuclear weapon tests, across the world.

Writing in the journal Geophysical Research Letters , scientists said it was the first time the stations had detected "multiple arrivals involving waves that travelled twice round the globe".

1. I wonder how many others are sneaking up on us.

The object was undetected before its atmospheric entry and its explosion created considerable confusion among local residents.

Imagine one twice the size hitting a major city with no advance warning.
