Kilauea Volcano roared to life as a 500ft (152m) lava fountain soared into the sky.

Stunning footage shows the fiery blast, with molten rock spewing from the crater on Sunday, May 11.

The eruption marked Episode 21 in the volcano's current phase of activity.

Lava began to ooze across the crater floor, fed by the forceful fountain at its core.

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.
