Preliminary report on the resistivity measurements on the islands of Oahu and Hawaii, Hawaii

Abstract

During the months of December, 1965 and January, 1966, a feasibility study conducted by the U.S. Geological Survey in cooperation with the Department of Land and Natural Resources of the State of Hawaii and the Institute of Geophysics in Hawaii. The purpose of the investigation was to determine the usefulness of the resistivity method in augmenting the solution of hydrogeological problems on the islands of Hawaii. Electrical measurements were carried out on the northern part of the island of Oahu near Waialua, as well as on the island of Hawaii near Pohakulua and Humuula. The electrical measurements consisted of intermediate and deep soundings using the Schlumberger as well as the equatorial configurations. In the following the basic fundamentals of the method will be briefly outlined then the results of the investigation will be presented and analyzed.
