Volcanic Activity Summary:
Mauna Loa has been quiet for the past three months since the eruption ended on December 13, 2022. The number of earthquakes beneath Mauna Loa’s summit has returned to background levels. Inflation of Mauna Loa continues as magma replenishes the summit magma chamber.
Accordingly, the USGS Hawaiian Volcano Observatory (HVO) is lowering the Volcano Alert Level for ground-based hazards from ADVISORY to NORMAL and the Aviation Color Code from YELLOW to GREEN.
In conjunction with this change, Mauna Loa updates will change from weekly to monthly, with the next monthly update on April 6, 2023.
