Kansas Geological Survey uses Geophysics to Find Border Tunnels

February 5, 2008 rockman Comments Off

The Kansas Geological Survey has some interesting seismic equipment that they have used on behalf of the U.S. Department of Homeland Security to look for drug tunnels along the US-Mexico border. I’ve never seen anything quite like this. The sensors all appear to be placed within an old fire hose and mounted onto a Bobcat Toolcat utility machine. On the front of the vehicle is a cyllinder with a 60-lb weight that gets dropped. Read on. (Photo by Richard Gwin, LJWorld.com)
