Mauna Loa Summit Closed Until Further Notice Due to Volcano’s ‘Heightened Unrest’

The Mauna Loa summit at Hawaii Volcanoes National Park is closed until further notice due to the volcano “experiencing heightened unrest,” according to an advisory posted by the Hawaiian Volcano Observatory on Thursday.

The volcano has a “yellow” alert level, the second of four levels.

Its closure is a “precautionary measure,” according to the National Park Service, and will mostly affect backcountry hikers who were planning on reaching the summit.

However, Mauna Loa Road and the Mauna Loa Lookout – which is at 6,662 feet elevation – remain open. Guests can also visit the main section of the park.

U.S. Geological Survey’s Hawaiian Volcano Observatory scientists said the volcano “is not erupting and there are no signs of an eruption at this time.”
