A Hydrogeophysical Survey Using Remote-Sensing Methods from Kawaihae to Kailua-Kona, Hawaii

Abstract

Several geophysical techniques have been specialized for applications to exploration for ground water in an insular basaltic environment. This article describes a multidisciplinary application of several such techniques to the Kona Coast of Hawaii in Hawaii. Aerial infrared scanning and low-level aeromagnetic surveys were the major reconnaissance techniques. For detailed study, modified audiomagnetotelluric and D. C. resistivity profiling methods were used. The improved knowledge of subsurface structure confirmed the expectation that no large flows, such as suitable for commercial exploration, occur in that coastal sector.
