Now for a scientific look at how this eruption is playing out beneath the surface.
IVAN CABRERA, CNN METEOROLOGIST: This is the layout here of Leilani Estates. There's the evacuation zone. There are the closed roads. The new fissures have impacted the eastern area. So, we'll continue to monitor that, but this whole area, folks have been taken out of the way with good reason as you can imagine, as these things continue to pop out just every few hours, every day or so.
This is the lake, of course. This is the account (ph) that I've been showing you the last few days, noticing that as the lake drained its lava, it went underground and that's the lava that's coming up to the fissures. I think again, that's going to be the main threat.
Notice as this continues to go down over the last several days, and one of our last pictures here, we can't see the lava anymore. That's an infrared camera, so the red you're seeing there, that's basically just heat signature here.
So, as that lava drops into the crater and into the basically a water table, let's talk about what could potentially happen as far as this explosive eruption here as we check in with our volcano. There's the lava and again what happens is, you get these rocks that will continue to fall down and that will create a blockage. And I don't have to tell you what happens with the kinds of temperatures we're seeing in here. We're talking about temperatures well into 1,500 to 2,000 Celsius, right?
Those rocks blocking that passageway at some point are going to give and once that goes into the water tables as you see there, we're going to have -- watch out -- quite an explosion here.
But again, I'm really not too concerned about this. It's going to be a spectacular eruption when it happens, but I think, Cyril, because they have evacuated people out of the way, these boulders would sometimes can be the size of a school bus are not going to be impacting many folks. This is going to be within a few meters of the crater here and before that happens, you must imagine people will be getting out of the way, and that's why they closed the National Volcano Park there in the big island.
