A magnitude 6.9 earthquake on May 4 , 2018 resulted in the slump moving about two feet . It appears to have been precipitated by vibrations caused by the movement of magma in the eastern rift zone of Kilauea , and in turn the earthquake preceded further volcanic activity . This could fit into a model of correlation between earthquakes and eruption events described for the earthquakes in 1868 and 1975
