Transcript for 'GMA' Flies Drone Over Erupting Volcano Live
Okay, everybody. It is time. I can't do it alone. We need a drone and need a drone operator. That would be Eric Cheng, the director of aerial imaging at dji. Let's get this started. We have about a minute until that drone gets over the edge and into that lava field. In the mean time, Bjorn oddsson is with the civil protection -- Yes. You are going to help me kind of describe what's happening. We have the cameras on the drones. We'll get into that lava field. Somewhere we're not allowed to go. No, basically not. Too dangerous for a human. And all the way into the crater where you have temperature up to 2100 fahrenheit so it's very hot. And that lava field is the size of Manhattan. Yes, it's 85 kilometers but has been pouring on to the area here and it's flowing 40 kilometer as way from the mother volcano underground and comes up here in this crater. That's what's amazing. While we're doing this we're able to see through Eric's cameras what the drones are seeing so Eric will stay quiet and focus because he's a responsible drone operator and has a lot of experience in this. Does it excite you that we're going to see parts of science and parts of the world that we've never been able to get this close to. It's very interesting technique that you can fly over there and looking into the crater without being there. So on the safe side as we can stay. We're learning something all the time. You have cameras mounted all over. Yes, definitely. You've been studying Iceland's volcanic eruptions. This is a place, you guys, that is always moving. It is moving. Constantly going. Iceland is growing then in the middle here where we have the active volcano, magma and lava coming up. Eric, how are we doing? Are we getting close. Yeah, we're getting close. The moment is almost here. We'll get up and over the lip. What are we seeing? Can you describe Bjorn. The crater itself here that's in the middle of the lava and the lava field voups it and in the beginning it's longer with a wall of fire but with time since we came here last time it's been growing and merging into one crater so there is like a bubbling pot with magma coming up through the ground and flows with the river. We have to stay this far away because the gases are toxic. You can see all the gas and toxic is going the other direction. Bjorn, it's happening right here. Oh, my gosh, you can see it. Look at this. We're just getting inside that crater. So there it is cooking the lava and lava flows into the tubes and that feeds the whole area of lava. Wow. Eric has that look and he can get even closer and we're able to get just the detail that you can see, so, again, over 2100 degrees inside there and it is bubbling and at times before this, it was erupting and you would see a wall of fire, but this is enough fire for me. I mean -- Yeah, it was but in the beginning it's gas, it goes up and you have a wall of fire with several hundred meters of fire but has slowed down but still is very active. You can see the walls here. You see the steam coming up. Is that just heat? Yeah, the steam is both gases and also water which is coming from the magma itself. Wow. Again, the video you guys are seeing is something that really no one has been able to do live here being able to get inside a volcanic eruption and even it's bubbling there and you can see the river. Did you just see that, the chunks of ash falling off the side and it's constantly changing. Bjorn was telling me the sides of that crater have already in the last couple of months since August when this became very active it started falling apart and changing shape. George. Yeah, I just want to -- what can we learn from what the drones are picking up right here? So, George is asking what can we learn from what the drones are picking up. If we're able to get this close -- What is important is to monitor the area and see the change with time so if you take images from drones or other equipment, we can compare from time to time what's happening. Aviation is a huge concern when it comes to niece and know in 2010 that was a big deal. That was a big deal then we'd corruption and the glacier and ash plume going into the atmosphere. In whole this is a lava eruption and no ash is emitted. Right now. Right now. But there's always a fear there could be another ash eruption and saying flash flooding could be a problem. If this lava you're seeing here is underground and tars melting all of the glacier. It does so the largest problem associated with that is because Icelandic volcanoes are often capped by the glacier. All behind is a glacier, the largest in Europe. If eruptions tart it melts the ice and produces a water that can flash -- Can go over roads. If it breaks through -- Can we get any closer at all, Eric? Is there any way -- We can get a little closer. How far up are we. At 120 meters. Like 380 feet. 400 feet. 380 feet over it. Oh, my goodness. Wow, but what you have to also say this lava field is the middle of Iceland. Far away from anyone. Not affecting anyone right here but has so many other implications H is amazing. Look at that river of lava. I mean, you can see just the detail in there and, again, what we can learn from this, not only in volcanic eruptions but also I think of this in the way of science, in the way of storms. We've used them in part in flooding when people need to see their hopes in wildfire, not able to get into places drones have in a responsible way a huge future in science and, Eric, we were talking about the exponential growth of drones and this alone tells you -- I mean isn't this just a wild moment. It's changing every few months and couldn't have done it a few months ago. Imaging is so much more precise than we've been able to see before. Oh, you guys, don't you love? It's unbelievable. You can feel the heat. Can you feel the heat where you are? I mean what is the feeling for you, ginger? You know, I have to tell you we're three-quarters of a mile away just for safety purposes and it's lots of cold air but when we flew right over it, it was hot.
