| Synopsis | The Ka'oiki seismic zone is below the southeastern flank of Mauna Loa Volcano and is one of the most active seismic zones in Hawai'i (Okubo, 1995 #6967). The 1974, 1983, and possibly the 1962 Ka'oiki earthquakes are responsible for surface fault ruptures, a series of en echelon left-stepping fractures (Endo, 1985 #6941; Jackson and others, 1992 #6946; Wolfe and Morris, 1996 #6977). |
