Report prepared by the Hawaiian Volcano Observatory:

Mauna Loa is not erupting. Slow extension, as measured by GPS receivers on either side of the volcano, has resumed after a hiatus of a few weeks.

Tiltmeters have recorded no significant changes.

Gas sensors continued to record background gas concentrations within a crack in the crater floor.

Mauna Loa remains seismically quiet with few earthquakes occurring beneath the summit and several located within the Kao'iki seismic zone between Mauna Loa and Kilauea volcanic summits. Since the beginning of January, 2005, HVO analysts have rarely located more than 10 earthquakes per week beneath Mauna Loa summit.
