USGS Volcano Hazards Program Volcano Update
HVO update page and observatory web site
Mauna Loa is not erupting. Minimal extension, as measured by GPS receivers on opposite sides of the volcano, continued.
Tiltmeters have recorded no significant changes other than abrupt offsets that are related to instrumental issues, severe weather, or significant earthquakes.
Sensors within a fissure in Moku`aweoweo crater floor reported gas concentrations and fumarole temperatures within normal values.
Since the beginning of January, 2005, HVO analysts have rarely located more than 10 earthquakes per week beneath Mauna Loa summit and 1-5 earthquakes beneath the Kealakekua area of west Mauna Loa. The Kao`iki seismic zone between Mauna Loa and Kilauea volcano summits remained active with an average of about 10-40 earthquakes per week; these numbers may reflect increased seismic activity nearer Kilauea summit rather than increased Ka`oiki activity.
