This is the spectacular moment lava fountains spewed from Kilauea Volcano in Hawaii.

Stunning footage shows hot molten rocks flowing out from the crater with smoke billowing in the air.

Authorities said Episode 17 of the Halema'uma'u eruption began at 10:15 pm HST on April 7. Lava started overflowing from the south vent, marking the latest phase of this ongoing volcanic event.

Before the eruption, a glow from the south vent grew brighter around 9:20 pm HST on the same day.

By 2:50 am HST on Tuesday, lava had spread across the Halema'uma'u crater floor, fed by low spatter fountains ranging from 15 to 30ft (5-10 metres).

Experts predict that high fountains could follow the same course.

This eruption, which began on December 23 of the previous year, follows a pattern of brief, explosive episodes—each lasting around 13 hours, separated by pauses ranging from one day to nearly two weeks.

Kilauea is the world's most active volcanic mass and is the central feature of Hawaii Volcanoes National Park. Its caldera is nearly three miles long and two miles wide, with an area of more than four square miles.
