Mauna Loa , Hawai : Seismicity remains elevated .

Activity Summary:
Mauna Loa is not erupting. There have been no significant changes in seismicity recorded beneath Mauna Loa over the past week. Seismicity remains elevated above the long-term background level, as shallow earthquakes continue to occur mostly beneath Mauna Loa’s upper Southwest Rift Zone at depths of less than 5 km (3 mi). Global Positioning System (GPS) measurements show continued deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation recently occurring mainly in the southwestern part of the magma storage complex.

Background:
Mauna Loa is the largest active volcano on our planet, rising gradually to 4,170 m (13,681 ft) above sea level. Its long submarine flanks descend an additional 5 km (3 mi) below sea level to the ocean floor. The ocean floor directly beneath Mauna Loa is, in turn, depressed by the volcano’s great mass another 8 km (5 mi). This places Mauna Loa’s summit about 17 km (56,000 ft) above its base. The enormous volcano covers half of the Island of Hawai?i.
