Abstract
A knowledge of the geological structure of the east rift of Kilauea Volcano, Hawaii, greatly helped in understanding the hydrothermal process of a geothermal reservoir found there. The source of energy was a hot, broad dike complex at a depth of 2.3 km. The geothermal reservoir is located in a rock layer with fractures caused by tensional stresses. The reservoir was capped by a self sealing process due to filling of fractures by secondary minerals.
