AHALA, Hawaii – Hawaii residents are facing the highest volcanic activity alert after officials warned Tuesday that the Big Island’s Kilauea volcano is growing more explosive — as a massive ash cloud grows in the sky.
The U.S. Geological Survery upgraded its previous volcano warning from “orange” to “red,” signifying that an “eruption is forecasted to be imminent with significant emission of ash into the atmosphere likely,” or that an eruption is already underway.
“At any time, activity may become more explosive, increasing the intensity of ash production and producing ballistic projectiles near the vent,” local officials told Fox News amid the alert, which was issued just before 1:30 p.m. local time.
Nearly 20 fissures have opened since the Kilauea volcano started erupting 12 days ago. On Monday, another fissure spewing lava and unhealthy gas opened up, and a crack in the Earth that emerged a day earlier was sending molten rock on a slow run for the ocean, officials said.
The eruption has destroyed about two dozen homes in the Leilani Estates subdivision on the Big Island.
Volcanic air pollution and ashfall have been reported in Pahala, and National Weather Service radar and pilots have reported the top of the volcano’s ash cloud is 10,000 to 12,000 feet above sea level.
In Hilo, Sandra Barnes told Fox News that she’d seen the ash cloud mid-morning between Pahoa and Volcano, Hawaii.
“I had to stop and take a picture,” she said. “That was a few hours ago. God knows what it looks like now. My kids and my mother are up there now.”
Down Highway 11, the main artery connecting the east and west side of the Big Island, a string of cars sit near the entrance of Volcano National Park. Though the park is closed, vacationers and some locals watch the ash fall from there.
“We’re not sure if it’s safe but it’s amazing,” Paul Rodaeo, a visitor from Oregon, said. “There really isn’t much more that’s open.”
Nearly 2,000 people have been told to evacuate since May 3.
