I found a site that plays back the earth movement of the Japanese earthquake that happened a year ago as sound clips. The seismic data is speeded up since the “sound” of an earthquake is of too low a frequency for our ears to detect. On the Web site, the part labeled “Hearing the Japanese Earthquake - Clip 2” is the most frightening. Turn up your speakers and grab your chair arms and remember that the clip is sped up 100 times faster than real time. While you listen to it, imagine an enormous miles-long chunk of the Pacific Ocean floor shoving itself under the crust on which Japan resides.The aftershocks will continue for years, perhaps decades.
