This is Dick's recording of the 2nd big aftershock today - originally registered at 6.9 and later downgraded to 6.7. Sudden motion sensors surrounding the hard drives in Macintosh computers are used to record the seismic motion of earthquakes.

Be sure to check out the older posts for earthquake photos.

Thanks to all for their concerns for our safety and well-being!
