The summit is inside Hawaii Volcanoes National Park and away from residential communities.

A one-way route that opened to manage traffic from throngs of people watching the lava would close Thursday, county officials said.

The volcano is still erupting, but the lava that was feeding the flow heading toward Saddle Road has been cut off.

And at the top hikers find a "loo with a view."

With lava slowly approaching the only direct east-west road connecting Hilo and Kona, residents and businesses are planning for longer commutes, higher fuel bills and other impacts.

Gabi Laske, a geophysicist at the University of California-San Diego led one of the first projects to map the deep plumbing that feeds the Hawaiian Islands’ volcanoes and explains where lava comes from.

Hawaii County hasn't finished buying out property owners after the 2018 lava flow that devastated Leilani and Kapoho, and here comes another potential disaster.

UPDATES: The eruption began late Sunday in the summit caldera of the volcano on the Big Island following a series of closely spaced, fairly large earthquakes.

Scientists say an eruption isn't imminent, but they are on alert because of a recent spike in earthquakes at the volcano's summit.

Officials say the volcano isn't erupting and shows no signs of an imminent eruption, but aftershocks could continue for several days.
