Letters: December 2001

A Shaken World "Seismic Shift" [September] was very interesting, particularly in light of the recent attacks on New York City and Washington, D.C. I was impressed by the extent of information obtained from the seismic record of the Kursk explosion. I would be very interested in learning about the kind of seismic data and information that was obtained from the terrorist attacks. I am also wondering if this technology is being used (or has been used in the past) to gather information on terrorist organizations.
