Geologists have warned that Kilauea may be entering a phase of explosive eruptions, the likes of which Hawaii has not seen in nearly a century, that could hurl “ballistic blocks” and dust towns with volcanic ash and smog.

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

A new fissure opened just a half mile from a geothermal power plant, Hawaii Governor David Ige set up a task force to remove pentane fluid used in the plant’s turbines. If the chemical ignites, the resulting explosion could create a blast radius of up to 1 mile.

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 about 2,000 residents.

A new area just to the west of the residential area was evacuated on Wednesday after toxic clouds of sulfur dioxide started shooting up through cracks in a road. “As more fissures open and toxic gas exposure increases, the potential of a larger scale evacuation increases,” Ige said.
