The move will make federal financial assistance available to state and local governments as they fix roads, public parks, schools and water pipes damaged by the eruption.
Hawaii County Civil Defense officials urged residents in a community near Kilauea Volcano to be vigilant amid ongoing volcanic activity and hazardous emissions - and to be prepared to evacuated on short notice, CBS Honolulu affiliate KGMB reports.
It's uncertain how big the explosions could be but scientists have said that Hawaii's Kilauea volcano appears to be mimicking behavior last seen in 1924. 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 it happens again, the danger zone could extend about 3 miles (5 kilometers) around the volcano, Mandeville said.
"We've got all the warning signs we need", he said. Rather it experiences effusive eruptions, where magma moves along rifts below the surface before rising and pushing up through fissures in the earth.
Authorities have accelerated the timeline for moving flammable pentane from a Hawaii geothermal plant that's near communities where lava has oozed from cracks in the ground. Brantley said a Global Positioning System receiver left in an area southeast of Nanawale Estates, on the other side of Highway 132 from Leilani Estates, had moved about 8 inches Thursday.
"I don't think that people should expect any additional warning", he said Friday afternoon. "We really don't know for certain", he told reporters on a conference call.
He said the area threatened by an eruption stretches from Kapoho, east of Leilani Estates, down to Kalapana.
She said hotter, fresher and gassier magma can result in more voluminous lava flows.
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.
In coming weeks, the summit crater could eject blocks up to 2 yards in diameter a little less than a mile away, the United States Geological Survey said.
Local meteorologists said the change in prevailing winds could send Kilauea's volcanic smog, or vog, northwest to Maui and other islands in Hawaii.
