Kilauea, an active shield volcano on Hawaii's Big Island, has erupted.

The Hawai'i Volcanoes National Park confirmed the news on Twitter, as did the Hawaiian Volcano Observatory.

In a statement Sunday night, the HVO/USGS said that shortly after 9:30 p.m. Hawaii Standard Time, "the USGS Hawaiian Volcano Observatory (HVO) detected glow within Halema?uma?u cra

ter at the summit of Kilauea Volcano. An eruption has commenced within Kilauea's summit caldera."

They said the situation is "rapidly evolving" and they will provide more information about the eruption when they have it.

"Accordingly, HVO has elevated Kilauea's volcano alert level to WARNING and its aviation color code to RED," they said.

Ash caused by the eruption will likely fall in the communities of Pahala, Wood Valley, Naalehu and Ocean View, NOAA's National Weather Service announced. They also warned residents to avoid excessive exposure to ash, which is an eye and respiratory irritant.

"Those with respiratory sensitivities should take extra precaution to minimize exposure," they said.
