Notes
The assessment effort consisted of a reexamination of existing Schlumberger sounding (Hussong and Cox, 1967; Adams et al., 1970) and time-domain electromagnetic (Klein and Kauahikaua, 1975) data for the rift area (Kauahikaua and Mattice, 1981) The electrical resistivity data acquired on the southwest rift delineated two distinct basement resistivity structures northwest of the rift zone: a high-resistivity basement at approximately 60 m a.s.l, and located north of a prehistoric fissure, and a low-resistivity deep basement (20 m a.s.1.) to the south and east of this fissure (Figs 48, 49). These data suggest that a high-level body of cold freshwater is impounded to the north of the fissure (which is acting as a hydrologic barrier) and a deeper, warm fresh to saline aquifer lies to the southwest (Kauahikaua and Mattice, 1981).
