Mauna Loa continues to erupt, locals prepare for major upheaval

Many on the Big Island of Hawaii are bracing for major upheaval if lava from the Mauna Loa volcano slides across a key highway and blocks the quickest route connecting the two sides of the island.

The molten rock could make the road impassable and force drivers to find alternate coastal routes in the north and south. That could add hours to commute times, doctor's visits and freight truck deliveries.

The lava is oozing slowly at a rate that might reach the road this week. But its path is unpredictable and could change course, or the flow could stop completely and spare the highway.

The slow-moving flow stayed consistent throughout the weekend.

USGS did lower the notice to airmen from red to orange meaning there is no threat to regional air traffic.

There are more affordable housing options on the island's east side, home to the county seat, Hilo.

But many jobs at beach resorts, in construction and other industries are readily available on the west side, where Kailua-Kona is located.

Saddle Road, also known as Route 200 or Daniel K. Inouye Highway, connects the two communities.
