Structural Damage to the Financial District
An anonymous submitter sent in a couple of links to damage reports on the World Trade Center complex - a nifty 3D map of the center and surrounding areas showing which buildings have been damaged or destroyed, and a discussion of how exactly they're going to excavate the below-ground area of the complex considering that it is below sea level.
See article here.
There is a LIDAR topo-map of the WTC area - click the first link in the "Multimedia" secton on the right of the page ("Mapping the Surface of a Disaster").
Pretty disturbing to see just two 60-foot mounds, especially in the cross-section view.
