HONOLULU (AP) — Hawaii authorities on Saturday told several dozen residents near an active lava flow to prepare for a possible evacuation in the next three to five days as molten rock oozed across a country road and edged closer to homes. Officials were going door-to door to about 50 homes to keep residents informed of the lava's movement, said Darryl Oliveira, the director of civil defense for Hawaii County. The presence of hazardous materials — like a pile of tires or a stockpile of chemicals — in the flow's path would also trigger a mandatory evacuation order, he said. Sporadic suspensions in the lava's movement gave emergency crews time to work on building alternate routes to town in the event the flow covers the main road and highway.
