Hawaii volcano erupts anew, residents urged to shelter

Hawaii volcano erupts anew, residents urged to shelter

An ash cloud rose up to 30,000 feet above sea level following the explosion at 4:17am local time (3:17pm BST) from Halema'uma'u crater.

"At any time, activity may again become more explosive, increasing the intensity of ash production and producing ballistic projectiles near the vent", it said in a statement. "It's not going to be the only one".

The US Geological Survey said the rocks and large pieces of splatter reached a height of 500 feet.

Dr Josh Green, a state senator who represents part of the Big Island, said the immediate health risk comes from ash particles in the air.

Most residents found only thin coatings of ash, if they saw any at all, as winds blew much of the 30,000-foot (9,100-metre) plume away from people. Pahala is the closest town west of the summit crater.

Hawaii's emergency management agency advised people in the area affected by ash to stay in their homes if possible.

Linda Ugalde, a 20-year resident of Volcano, said she heard and felt nothing, but stepped outside of her home at the Volcano Golf Course subdivision about 10 minutes after the alert to find a film of dark gray ash coating the railing on her lanai and the plants in her garden and yard. In recent days, smaller eruptions there sent ash surging into the sky. This may be a potential precursor of the Big One, when boulders are expected to fly.

The global airports in Hilo and Kona are open, officials said.

The water would then flash into steam, "and steam as we know is a very powerful source of energy, a very powerful propellant", Rowe said. But this is not Kilauea's first massive eruption. Kilauea is a shield volcano, which means it emits fluid basalt lava and has a broad dome shape, instead of a steep peak.

Other than phreatic eruptions can still pose a deadly threat to anyone near the eruptive vent - which is somehow extremely hard to forecast, Poland stated. No new fissures, or vents in the ground, opened Thursday, he said.

About 2,000 people have been evacuated.

Phreatic eruptions are "much more random", Poland said.
