As lava continues to flow into the northeast rift zone from Mauna Loa’s summit caldera, the DLNR has also closed recreation areas on the mountain.

“No one should be accessing Mauna Loa at this time. Our sole focus is on public safety, which depends on where lava ultimately flows,” said Bergfeld.

DOFAW first closed the entire Mauna Loa Forest Reserve on Monday, Nov. 29. Kipuka Ainahou Nene Sanctuary, Ainapo Trail and cabin and the Kapapala Forest Reserve were also closed.

The following day, Unit J of the Kapapala Game Management Area was closed.
