Hawaii volcano's lava oozes toward key Big Island highway

KAILUA-KONA, Hawaii (AP) — Rivers of glowing lava oozing from the world’s largest volcano could swallow the main highway linking the east and west coasts of Hawaii’s Big Island as early as this weekend, and there’s nothing humans can do to stop it, experts said.

Mauna Loa awoke from its 38-year slumber Sunday, spewing volcanic ash and debris into the sky. The molten rock is drawing thousands of awestruck viewers to Route 200 as it passes near Volcanoes National Park, and they endure a thick smell of volcanic gases and sulfur to watch the wide stream of lava creep closer.

“It’s a thrill,” said Kathryn Tarananda, 66, of Waimea. She set two alarms to make sure she didn’t miss her chance to see the sun rise against the backdrop of the eruptions. “We’re out in the middle of raw nature. It’s awe inspiring that we live in this place. ... I feel really, really fortunate to be an islander.”

The lava tumbling slowly down the slope has drawn within several miles of the highway, which runs through old lava flows. Known as Saddle Road, it bisects the island, connecting the cities of Hilo and Kailua-Kona. If it becomes impassable, the alternative is a longer coastal road, adding several hours of driving time.

Ken Hon, scientist in charge at the Hawaiian Volcano Observatory, said Wednesday that at the current flow rate, the lava could reach the road in as little as two days, though it will likely take longer. "As the lava flow spreads out, it will probably interfere with its own progress,” Hon said.

Lava crossed the Mauna Loa Observatory access road Monday night and cut off its power, Hon said. It’s the world’s premier station that measures heat-trapping carbon dioxide in the atmosphere. The federal government is looking for a temporary alternate site on the Hawaiian island and is...
