Hawaii volcano Kilauea: Explosive eruptions,

Share

Kilauea has destroyed 36 structures - including 26 homes - since May 3, when it began releasing lava from vents about 25 miles (40 kilometers) east of the summit crater.

Now experts fear Hawaii's Kilauea volcano is at risk of explosive eruptions that could emit "ballistic projectiles", the USGS says.

The Puna Geothermal Venture plant has about 50,000 gallons of pentane. "Thank goodness that everyone's alive and safe".

Magma is draining out of the volcano's sinking lava pool and flowing underground tens of miles eastward before bursting to the surface in and around homes on Kilauea's eastern flank, just a few miles from Pahoa.

"When you start seeing ferns go brown overnight, it's like, 'Wow, I gotta get out of here, '" said Peters, sitting at a Red Cross evacuation centre at a sports centre in nearby Pahoa. Hawaiian Volcano Observatory Scientist Tina Neal said Friday that an analysis of rock samples indicates the lava's chemistry is similar to that from a 1955 eruption.

If an explosive eruption happens, a summit blast could also release steam and sulfur dioxide gas. The agencies also said ash clouds would rise to greater elevations, dispensing ash over wider areas. "Secondly, we're uncertain as to how long it will take for conditions to generate an explosion once the conduit has been emptied below the water table".

Hawaii Volcanoes National Park will close Friday due to the possibility of explosive steam at the summit of Kilauea volcano, according the National Park Service.

At the request of the park, the FAA has issued a Temporary Flight Restriction that extends 20,000 feet AGL and a 12 nautical mile radius around the summit of Kīlauea.

Neal said fresher, hotter lava could emerge because magma has been moving down Kilauea's rift zone toward the area where the volcano is erupting.

The estimated cost to protect residents over the next 30 days is expected to exceed $2.9 million, according to the governor's office. More than a dozen fissures oozing lava have opened in the ground.

Residents of Kona on the west of the island have complained of volcanic smog, or vog, from the large amounts of sulfur dioxide and other pollutants spewing from Kilauea.

Don Swanson, a geologist with the Hawaiian Volcano Observatory, said the magma is likely to drop below the water table around the middle of the month. The asphalt road was describes as "mushy" from the heat. When the water hits the lava, it also steams.

The 13th and 14th vent erupted Tuesday in the Leilani Estates area, where roughly 1,700 residents were asked to evacuate last week.
