Hearing the Japanese Earthquake (3 of 3) (VIDEO) Georgia Institute of Technology This video is under embargo. Please login to access this video.

The initial noise, which sounds like distant thunder, corresponds with the Japanese mainshock. Afterwards, a continuous high-pitch sound, similar to rainfall that turns on and off, represents induced tremor activity at the fault. This animation not only help scientists explain the concept of distant triggering to general audiences, but also provides a useful tool for researchers to better identify and understand such seismic signals in other regions.
