The National Park Service is reporting progress in the battle against a wildfire that has burned 2,076 acres in the east rift zone of Kilauea Volcano.

The Napau fire was 50 percent contained today, the park service reported.

Lighter trades and rain helped the 50 National Park Service firefighters in their attempts to prevent the wildfire from spreading on its southern perimeter to the Chain of Craters Road.

The wildfire was sparked on March 5 by lava from the Kamoamoa eruption.

The fire, which had threatened a rainforest home to endangered species, is about seven miles southeast of the Kilauea visitor center.
