Aerial footage of the aftermath of the Hawaii volcano eruption shows what happens when ocean water splashes onto molten lava.

Lava fragments falling from lava fountains at fissure 8 are building a cinder-and-spatter cone around the erupting vent, with the bulk of the fragments falling on the downwind side of the cone as it continues to feed a channelized lava flow that reaches the ocean at Kapoho during ongoing eruptions of the Kilauea Volcano in Hawaii, U.S. June 11, 2018.

"The summit explosion produced an natural disaster with a magnitude of 5.4", the U.S. Geological Service (USGS) wrote in a Twitter post on Wednesday.

The magma has been spouting out of fissures from the ground along Kilauea flank, causing mass evacuations from communities.

Kilauea volcano spews lava as high as 55 metres into the air in Hawaii.

The mixture of ocean water and lava also produces a toxic cloud called laze that the agency says can irritate people's eyes, lungs and skin.

The eruption stands as the most destructive in the United States since at least the violent 1980 eruption of Mount St. Helens in Washington state, according to geologist Scott Rowland, a volcanologist at the University of Hawaii at Manoa.

The Mount St. Helens eruption also ejected pyroclastic flows, which reduced hundreds of square miles (km) to wasteland, and killed almost 60 people and thousands of animals.
