MAUNA KEA (VNUM #332030)
19°49'12" N 155°28'12" W, Summit Elevation 13802 ft (4207 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
No significant activity was detected at Mauna Kea volcano during the past month. Seismic activity remained low, and was representative of background activity levels at the volcano; all earthquakes were of small magnitudes (below M3.0). The continuously recording Global Positioning System (GPS) instrument on Mauna Kea (MKPM, operated by NASA’s Jet Propulsion Laboratory) recorded no significant deformation in the past month.
Background: Mauna Kea is a shield volcano in the post-shield stage; it last erupted about 4,600 years ago. Monitoring is conducted by one GPS instrument and three seismometers on the volcano, plus instruments on adjacent Kohala Volcano and denser geodetic and seismic networks on the north flank of Mauna Loa to the south. With a summit at 4,207 meters (13,803 feet) above sea level, Mauna Kea is the tallest mountain in the State of Hawaii, and it is the tallest mountain on Earth when measured from its base on the ocean floor.
