MAUNA KEA VOLCANO (VNUM #332030)
19°49'12" N 155°28'12" W, Summit Elevation 13796 ft (4205 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

No significant activity was detected at Mauna Kea Volcano over the past month. There were 11 small magnitude earthquakes detected beneath the summit and flanks of the volcano, similar to average long-term earthquake rates. The single, continuously recording Global Positioning System (GPS) receiver atop Mauna Kea (operated by NASA’s Jet Propulsion Laboratory) recorded no significant changes in deformation

Background: Mauna Kea was last active about 4,600 years ago. Monitoring is conducted using three seismometers and one GPS receiver on the volcano plus instruments on adjacent Kohala volcano and denser seismic and geodetic networks on the north flank of Mauna Loa to the south.


This notice contains additional volcanoes not displayed: Kilauea (NORMAL/GREEN), Hualalai (NORMAL/GREEN), Haleakala (NORMAL/GREEN), Loihi Seamount (UNASSIGNED/UNASSIGNED).
