Hawaii Kilauea Volcano Eruption: More Big Island Residents Told Prepared For Evacuation

The Turrialba volcano spews smoke and ash in May 2016 in Cartago Costa Rica. Experts say it is the strongest eruption from the volcano in the past six years

George Szigeti, CEO of the Hawaii Tourism Authority says Kilauea is being monitored constantly and says the Big Island is "immense" and there are large parts that are unaffected by the volcano.

A new fissure roaring like jet engines and spewing magma has opened on Hawaii's Kilauea volcano, piling lava as high as a four-story building, as the area torn by the volcano's eruption spread.

Residents of Puna are also being told they can evacuate voluntarily to one of two evacuation shelters at Pahoa and Keaau community centers.

Hawaii County authorities advised residents on the Big Island through a text message to monitor their sensitivity to increased levels of SO2, a toxic gas. Hotspots include either lava flows or new fissures, which show up as yellow to the ASTER.

"The situation remains unstable", she said.

Geologists are warning a possible explosion at the summit of Kilauea could be the largest in almost 100 years, hurling boulders the size of refrigerators.

"Many of these earthquakes are related to the ongoing subsidence of the summit area and earthquakes beneath the south flank of the volcano".

What followed was a flurry of earthquakes as huge volumes of magma - the term for lava beneath the surface - drained back through deep-underground passages that carried the molten rock far downslope.

Meanwhile, scientists at the Hawaiian Volcano Observatory said Friday that East Rift Zone intrusion and seismic activity appear to be moving northeast. If it falls below the water table, water will pour onto the lava, generating steam that will likely explode from the summit in a shower or rocks, ash and sulfur dioxide gases.

The lowering of the lava lake at the volcano "has raised the potential for explosive eruptions in the coming weeks", the agency said in its statement.

"He said 'That lava's underneath your house, '" said Conda.

President Donald Trump declared a major disaster in Hawaii following a request by the state's governor due to the volcanic activity continuing to wreak havoc on the island.
