Quoting: Anonymous Coward 35224508 Current Volcano Alert Level: ADVISORY Current Aviation Color Code: YELLOW Activity Summary: Rates of deformation and seismicity at Mauna Loa remain above long-term background levels. Mauna Loa is not erupting. Global Positioning System (GPS) measurements continue to show ground surface deformations related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation occurring mainly in the southwestern part of Mauna Loa’s summit caldera magma storage complex. Shallow earthquakes, at depths less than 5 km (3 mi) beneath the south caldera and upper Southwest Rift Zone, continue to be the most frequently occurring type of seismic activity through the past week. Earthquake rates remain elevated relative to previously established baselines. Measurements from a continuously-monitored fumarole site within the summit caldera showed relatively steady fumarole temperatures and no significant changes in either sulfur dioxide or carbon dioxide concentrations in volcanic gas emissions.
