Mauna Loa is not erupting. No significant change in seismicity was recorded beneath the volcano in the past week. In the past week, earthquakes at Mauna Loa occurred mostly beneath the volcano’s south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi). Global Positioning System (GPS) measurements show 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.
Mauna Loa has erupted 33 times since its first well-documented historical eruption in 1843. Its most recent eruption was in 1984.
