No unusual deformation or seismicity was detected.

Five earthquakes were located beneath Mauna Kea at depths greater than 13 km (8 mi), one event were located at shallower depths.
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. In addition, satellite radar interferometry data are available a few times per month with which possible deformation can also be evaluated.
