#Kilauea's south flank

Over the past two decades, scientists and members of the public have anticipated the occurrence of slow slip events (SSEs) on Kīlauea’s south flank. These events are recorded by the Hawaiian Volcano Observatory’s (HVO) continuous GPS network, which show as much as 2 cm (0.75 inches) of increased seaward motion of the flank over 2-3 days — equivalent to about a M6 earthquake.
