During the past week the Hawaiian Volcano Observatory (HVO) recorded 62 small-magnitude earthquakes on the volcano's summit and upper-elevation flanks. Most of these earthquakes occurred at shallow depths of less than 8 kilometers (~5 miles) below ground level.
Slow summit inflation continues to be detected by the GPS, consistent with magma supply to the volcano's shallow storage system.
Gas concentrations and fumarole temperatures remain stable.
