>> this is very sort of as soon as as soonas soupy,almost cement like consis. we're minding more about how they are going about it. the search dogs have been very helpful in the last couple days. when they sense something, the human assets, search and rescue workers deploy cameras. if they think there's an open space somewhere they can get to, listening devices to see of any signs of life. then they'll move debris by hand or with equipment they brought in. very, very difficult work. this is a debris field, a ragged edge squire mile. mixed in with the dirt is the remains of 35 houses, so all kinds of construction material, nails, propane tanks, sewage, all kinds of hazardous materials, anything that people might have had on hand, it's a really dangerous situation. add into that the fact that there's a massive scarf that has slid and continues to be very wet and unstable and could slide again and you have a very dangerous situation. they're taking every possible precaution to keep the searchers and those people out there safe. >> that's a scary situation there. w
