The Kilauea volcano on Hawaii's Big Island began to erupt afternoon, with flows currently confined to the surrounding crater floor, the US Geological Survey (USGS) said.

Webcam images show fissures at the base of the volcano's crater that are generating lava flows on the surface of the crater floor.

The Hawaii Emergency Management Agency wrote on X, the social media platform formerly known as Twitter, that the eruption "does not pose a lava threat to communities" though volcanic particles and gases may create breathing problems for people exposed.

The eruption was preceded by a period of strong seismicity and "rapid uplift" of the summit, according to USGS. The agency elevated Kilauea's aviation color code from orange to red as it evaluates the eruption and its volcano alert from watch to warning.

Located in a closed area of Hawaii Volcanoes National Park, Kilauea is one of the world's most active volanoes. In 2019, a string of earthquakes and major eruption at Kilauea led to the destructions of hundreds of homes and businesses.

The volcano erupted in January and June of this year.
