Hawaii's Kilauea volcano just threw a huge ash cloud 2 miles into the sky
News Hawaii was put on "red alert" Tuesday, after the Kilauea volcano sent a plume of gas and ash 12,000 feet into the sky, posing a hazard to residents and aircraft in the area.The U.S. Geological Survey raised the alert from orange to red, meaning a "major volcanic eruption is imminent, under way, or suspected with hazardous activity both on the ground and in the air." It's the first time the alert has been raised to red since Kilauea — one of the world's most active volcanoes — flared up on May 3."We're observing more or less continuous emission of ash now with intermittent, more energetic ash bursts or plumes," Hawaiian Volcano Observatory Deputy Scientist-In-Charge Steve Brantley told reporters.The activity at Kilauea in recent days has destroyed more than 30 homes, prompted the evacuation of more than 2,000 residents, and covered 115 acres in lava. Authorities say 21 fissures have opened, continuously emitting ash and "vog" — volcanic air pollution — which has fallen up to 18 miles downwind.
