A different Michael Cohen. Growing concerns about the volcano emergency in Hawaii. Geologists warning more explosive eruptions could be coming sending ash flying to an area already so devastated. ABC's kayna Whitworth has the latest. Reporter: This morning we're getting a closer look at some of the homes in the path of the kilauea volcano eruption where lava poured into the streets for the past week scorching houses and yards like this one. Over a dozen fissures have emerged over the last few days and on Wednesday an explosive eruption sending a torrent of ash into the sky. Our Marci Gonzalez was there. Oh, my goodness. That is just remarkable. Reporter: In recent years the volcano has been sending volcano into hard to reach areas along the coastline but in the last week more than 15 vents have burst open releasing lava, gas and neighborhoods. This right here is the biggest lava flow in Leilani estates. This is the one that continued on for about a half mile and as you fly over it, you can see it has taken down power poles and changed the entire landscape of this neighborhood. Underneath some 15 feet of lava rock is homes and cars. There is no sign of how far the lava will spread or when the eruption will stop. Police are now going door to door to evacuate residents near two new volcano vents. We hope that within, you know, weeks, a month maybe that we'll be back in here. Reporter: All of that toxic volcanic gas spreading for more than 60 miles. It's posing potentially deadly risks to everyone in the evacuation zone, especially to the elderly and those with breathing problems. Really thick and makes your eyes water. Your throat hurts. Everything hurts so your lunging literally ache so you got to just run. Reporter: Geologists are very concerned that kilauea could erupt violently in the coming days. They say this happens when the lava lake drops low enough to react with the ground water. It could throw Boulders out the size of cars. Michael. All right, thank you so much, kayna. I'm sure that's news no one wants to hear.
