Fresh lava flows could block Hawaii escape route within hours
PAHOA (Reuters) - Lava oozed toward a key Hawaii highway that serves as an escape route for coastal residents, after fresh explosive eruptions from the Kilauea volcano and magma flows that destroyed four more homes.
Molten rock from two huge cracks merged into a single stream and was expected to hit coastal Highway 137 within four to seven hours if it kept up its rate and direction of flow, the County of Hawaii’s Civil Defense Agency said.
Authorities are trying to open up a road blocked by a 2014 lava flow to serve as an alternative escape route should Highway 137 or another exit route, Highway 130, be blocked, Jessica Ferracane of the National Park Service told reporters.
The Hawaii National Guard has warned of mandatory evacuations should either road be blocked.
For weeks, geologists have warned that hotter, fresher magma from Kilauea’s summit would run underground and emerge some 25 miles east in the lower Puna district, where older, cooler lava has already destroyed 44 homes and other structures.
“Summit magma has arrived,” said US Geological Survey scientist Wendy Stovall said on a conference call with reporters.
“There is much more stuff coming out of the ground and its going to produce flows that will move much further away.”
