Sounds of the Japanese earthquake

Recordings from the thousands of sensors situated around Japan are being used to analyse the magnitue 9 earthquake in many ways.

Some data has been used to reproduce the sounds made as the plates moved. These are not real-time recordings, time has been compressed to enable the low frequency sound to be heard and produce in minutes or seconds what took place in hours.

There is an article complete with video clips on Newswise (here) and Science Daily (here). The research was originally published by the Georgia Institute of Technology.
