Mauna Loa is not erupting. There have been no significant changes in seismicity recorded beneath Mauna Loa. 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.
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.
