MAUNA LOA VOLCANO (VNUM #332020)
19°28'30" N 155°36'29" W, Summit Elevation 13681 ft (4170 m)
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. In the past week, earthquakes at Mauna Loa have occurred mostly in the south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi). Seismicity rates on Mauna Loa have not changed significantly this week and remain elevated relative to the long-term background rate. Global Positioning System (GPS) measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation 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.

Mauna Loa has erupted 33 times since its first well-documented historical eruption in 1843. Its most recent eruption was in 1984.

Activity Summary: Rates of deformation and seismicity at Mauna Loa remain above long-term background levels.

Mauna Loa is not erupting. In the past week, earthquakes at Mauna Loa occurred beneath the west flank of the volcano mostly in the 5 11 km (3 7 miles) depth range. In addition, earthquakes are occurring in south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi). Seismicity rates on Mauna Loa overall were lower this week compared with the previous update. Global Positioning System (GPS) measurements show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation occurring mainly in the southwestern part of the magma storage complex.

Thursday, July 14, 2016, 9:58 AM HST (Thursday, July 14, 2016, 19:58 UTC)


MAUNA LOA VOLCANO (VNUM #332020)
19°28'30" N 155°36'29" W, Summit Elevation 13681 ft (4170 m)
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.

During the past week, HVO seismometers recorded short bursts of earthquakes at depths of about 5 11 km (3 7 miles) beneath the upper west and north flanks of the volcano. Such activity has been detected before and is likely a response of the volcano to stresses related to slow accumulation of magma in the summit and upper Southwest Rift Zone magma storage complex. Ongoing addition of magma to this region is supported by ground surface deformation (inflation) measured by Global Positioning System (GPS) instrumentation across the volcano, as well as by satellite radar (InSAR).





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.

Mauna Loa has erupted 33 times since its first well-documented historical eruption in 1843. Its most recent eruption was in 1984.
