Abstract
The active central volcano Hengill, within the Neo-volcanic zone in SW-Iceland, is intersected by a major NE-SW trending fissure swarm. There is an abundance of hot springs and fumaroles within a high temperature geothermal area, which is characterized by a low resistivity anomaly some 120 km in areal extent. The central hottest part is about 50 km and is indicate by a resistivity high at depth. An aeromagnetic map shows negative anomalies, caused by hydrothermal alteration. The best geothermal prospects are presumably within the fissure swarm outside the central region.
