http://www.bbc.co.uk/news/science-environment-21730887 The great Tohoku earthquake in Japan two years ago was so big its effects were even felt at the edge of space. Scientists say the Magnitude 9.0 tremor on 11 March 2011 sent a ripple of sound through the atmosphere that was picked up by the Goce satellite. Its super-sensitive instrumentation was able to detect the disturbance as it passed through the thin wisps of air still present 255km above the Earth. The observation is reported in the journal Geophysical Research Letters. It's pretty amazing that it was heard so far out ! I wonder how much sound makes it up there?

Well, this is the edge of space, where there's still a very thin atmosphere. (Of course, sound can't be heard beyond that.) |
