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. The ground-based Volcano Alert Level for Mauna Loa remains at Advisory.

Mauna Loa is not erupting. Global Positioning System (GPS) measurements continue to show ground surface deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with a continuing inflationary trend occurring mainly in the southwestern part of Mauna Loa’s summit caldera magma storage complex.

Small, shallow earthquakes at depths less than 5 km (3 mi) were recorded beneath the south caldera and upper Southwest Rift Zone, the same area where most of the recent earthquakes have occurred. This past week, no earthquakes of magnitude 3 or above were recorded beneath the volcano.

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.






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.

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. Global Positioning System (GPS) measurements continue to show ground surface 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 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 occur. This week, two magnitude 3.4 earthquakes occurred near the summit. Following these events, no significant changes were observed in other monitoring datastreams, and the Volcano Alert Level for Mauna Loa remains Advisory.

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.





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.

Shallow earthquakes, at depths less than 5 km (3 mi) beneath the south caldera and upper Southwest Rift Zone, continue to occur.

Early Tuesday morning, a magnitude 4 earthquake occurred at a depth of 1.2 km (0.7 mi) beneath the southern caldera region. Following this event, HVO recorded no significant changes in deformation or seismic monitoring data. The Volcano Alert Level for Mauna Loa remains Advisory.

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.





Background: Mauna Loa is the largest active volcano on our planet, rising gradually to 4,170 m (13,681 ft) above sea level.

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.





Background: Mauna Loa is the largest active volcano on our planet, rising gradually to 4,170 m (13,681 ft) above sea level.
