Hawaii volcano could spew boulders the size of refrigerators

Hawaii volcano could spew boulders the size of refrigerators

Leilani Estates' 1,700 residents were forced to evacuate after Kilauea volcano erupted and caused lava to ooze from fissures in the ground last week.

Lava has destroyed at least 36 structures and covered more than 115 acres. Rather it experiences effusive eruptions, where magma moves along rifts below the surface before rising and pushing up through fissures in the earth.

Although the explosion was short-lived, geologists believe that the lava lake is still above the underground water table.

The latest upheaval at Kilauea began last week after the crater floor of a long-active side vent collapsed, triggering a plunge in the molten lake inside the larger crater at the volcano's summit. The water boils instantaneously when it comes into contact with the magma, resulting in a violent mixing of the two substances.

A summit explosion could also release ash, steam and sulfur dioxide gas. And for volcanologists, the eruption is an opportunity to share with the public what we know about how these massive, intricate systems work.

A man suspected of burglarizing homes in a neighborhood affected by the erupting volcano on Hawaii's Big Island has been arrested, police said.

What we're looking at: Remember those steam-driven explosions at the summit - the ones caused by groundwater entering the void left by the retreating lava?

"It's like when you drop a Mentos into a bottle of Coke: it starts making bubbles".

Kilauea has a history of phreatomagmatic explosions. It threw boulders as heavy as 12½ tonnes into the sky. In 1924, ash went to Hilo, Pahala, Makuu, and Hakalau. The trees in the photos are roughly 5 kilometres from Halemaumau.

The problem is the lava lake at the summit of Kilauea is draining fast, about 6.5 feet per hour, Mandeville said.

But most of the rest of the island is free of volcanic hazards, and local tourism officials are hoping travelers will recognize the Big Island is ready to welcome them. It could also send pebbles shooting into the air several miles away, the agency said. "And what the people here are going through is tragic", he told AFP. "If that happens, we're into a whole different situation", said U.S. Geological Survey Hawaiian Volcano Observatory geologist Janet Babb.

The Hawaii Property Insurance Association was founded in 1991 by an act of the state legislature "to provide basic property insurance for persons unable to purchase homeowners coverage in the private market due to the ongoing volcanic eruption" in certain "lava zones" on the island of Hawaii, according to the HPIA website.

If volcanologists can better understand Kilauea and underlying reasons for its seemingly unusual behaviour, Johnson said it could help them better understand other volcanoes. She says that while there is not now an active volcano in California, another eruption is inevitable.

Therefore, in the coming weeks it will be critical to follow the updates from the USGS and Civil Defense regarding the status of Kilauea, not only at the lava flow field down at Leilani Estates, but also at the summit.
