Oceanic Sounds of Last Year's Earthquake

Posted by Zonk on from the science-on-a-massive-scale dept.

DoctorBit writes "Columbia University's Lamont-Doherty Earth Observatory is reporting that some of their researchers have analyzed recordings of the underwater sound produced by last year's magnitude 9.3 Sumatra earthquake. By studying the ocean's sound waves rather than the Earth's seismic waves, the researchers measured the earthquake's speed and duration with unprecedented accuracy."

    The phrase "unprecedented accuracy" seems to imply that this technique can detect very minute underwater sounds. Would this technology also be applicable to detecting the barely detectable sounds of underwater nuclear submarines?
