Mauna Loa eruption information
Mauna Loa is no longer erupting. Lava supply to the fissure 3 vent on the Northeast Rift Zone ceased on December 10 and sulfur dioxide emissions have decreased to near pre-eruption background levels. Volcanic tremor and earthquakes associated with the eruption are greatly diminished.
Accordingly, the USGS Hawaiian Volcano Observatory (HVO) is lowering the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW.
Spots of incandescence may remain near the vent, along channels, and at the flow front for days or weeks as the lava flows cool. However, eruptive activity is not expected to return based on past eruptive behavior.
Daniel K. Inouye highway remains open in both directions. All areas adjacent to Daniel K. Inouye highway, Old Saddle road, and near the lava flow are closed and prohibited from access to the public for your safety.
This situation could change. For the most up-to-date information please see the following list:
