Man Hit by Lava Bomb Loses Lower Leg.
BALDWIN: Three weeks of volcanic activity in the Kilauea summit still bubbling over. More incredible pictures and a live look at the lava gushing thousands of feet into the air. And now a new danger on the roads. You'll see blue burning flames. Like the ones you see on your stove popping up on the streets. There are methane gas exploding in between cracks in the ground and this home is close to being swallowed by cracks in the front and backyard. We talked to a homeowner injured by one of the hot lava bombs.</s>DARYL CLINTON, HIT BY LAVA BOMB: It came right through there somehow and at an angle and just crashed into my leg about right here and snapped it in half at the ankle and foot to where my leg was basically broken in half. It was like a hinge point, ankle, foot, leg, so then I got caught on fire. Fell on floor and grabbed my foot and leg and held them together.</s>BALDWIN: I mean, unreal. James Webster is with me, a geologist with the American Museum of Natural History here in New York. Jim, I don't even know what to say. I went to Kilauea as a kid and seeing a guy in a hospital because of a lava bomb. What is that?</s>JAMES WEBSTER, GEOLOGIST WITH AMERICAN MUSEUM OF NATURAL HISTORY: So, a lava bomb is actually -- it was molten material that was blown out of a fissure or a small cone in the ground. And it is cooling as it moves through the air but still very high temperature. I'm not quite sure what temperature it was -- that hit the gentleman, but I guess it was just a massive amount of energy when it hit the leg and broke the bones from the ankle down.</s>BALDWIN: How does it burst up and -- and how is it propelled through the air?</s>WEBSTER: It is expanding gases. Just like I used a car with expanding gases to get here, steam expands, and you have lava at 2,000 degrees Fahrenheit and just add water and that is what happens.</s>BALDWIN: And can you put the pictures back up with the blue flames and the methane. This is the first I've seen of those pictures. Here you go. Can you just walk us through what we're look at?</s>WEBSTER: So, what is happening, you could see the trees are damaged. The tremendous heat from the lava, if it slowly moves and heats the vegetation, like the grass and such, in the air it will burn the ground. But if it moves over it quickly enough and covers it, will t will cook it and make methane gas which is extremely flammable. So once that ignites you get the blue flames.</s>BALDWIN: I mean just crazy what is happening and the fact this guy gets injured over a lava bomb in his house. Jim Webster, I have a feeling we'll be talking again. And I should mention CNN has a live lava cam 24 hours a day showing the pictures. All you have to do is click on CNN.com to watch it.
