No significant activity was detected at Mauna Kea Volcano during the past month. HVO seismometers recorded approximately 39 small-magnitude earthquakes (below M3.0) in the vicinity of the volcano. This earthquake count is on par with previous months. The continuously recording Global Positioning System (GPS) instrument atop Mauna Kea (MKPM, operated by NASA’s Jet Propulsion Laboratory) recorded no significant deformation.

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.
