Footage shows rivers of lava flowing across Kilauea volcano in Hawaii.

The United States Geological Survey (USGS) released a video capturing recent activity at Kilauea's latest eruption site on September 19.

Experts witnessed the raw power of nature as lava coursed through a channel over 50 metres wide.

The team, equipped with advanced monitoring technology, observed lava flows that stretched around 164ft across, highlighting the scale and intensity of the eruption.

The Hawaiian Volcano Observatory has downgraded the volcano alert level from watch to advisory as the Kilauea eruption ended on Friday and is unlikely to restart.

The recent eruption began on Sunday, September 15, and had four eruptive phases, concluding on Friday, September 20, around 10 am.

Authorities noted that seismic activity in the area has been low since then, and HVO seismometers no longer record tremors caused by magma within vents.

Kilauea is a highly active shield volcano, estimated to be between 210,000 and 280,000 years old, having emerged from the sea about 100,000 years ago.

Its last major eruption occurred between May and September 2018, displacing thousands of residents and destroying 716 homes.

During that eruption, lava flowed from 24 different vents, with one significant explosion sending debris 30,000ft (9,100 metres) into the sky.
