As of the morning of November 29, lava from the eruption of the Mauna Loa volcano on Hawaii's Big Island has been confirmed to have crossed the access road to NOAA's Mauna Loa Observatory and taken out power lines to the site. These circumstances have resulted in a pause in data being collected at the observatory.

All NOAA staff from the Mauna Loa Observatory are safe.

At this point the facility is not accessible.

NOAA will continue to provide updates as the situation develops.
