This is the spectacular moment a lava curtain spewed from the Kilauea volcano.

Footage shows a 150-metre fissure erupting on September 19, west of Napau Crater on Kilauea's middle east Rift Zone.

Officials said the eruption produced a curtain of lava reaching up to 20 metres.

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.
