Hawaii authorities scrambled to move tens of thousands of gallons of highly flammable chemicals from the path of lava on Thursday, and the state¡¯s governor warned mass evacuations might be needed as the Kilauea volcano¡¯s eruption became more violent.

After a new fissure opened on Wednesday about half a mile from a geothermal power plant, Hawaii Gov. David Ige set up an emergency task force to remove the pentane used in the plant¡¯s turbines. He cited estimates that if the fluid ignites, the resulting explosion could create a blast radius of up to 1 mile (1.6 km).

The Puna Geothermal Venture plant sits at the edge of the Leilani Estates residential area on Hawaii¡¯s Big Island where lava from 15 volcanic fissures has so far destroyed 36 structures, most of them homes, and forced the evacuation of around 2,000 residents.
