[SMP44-02] Characterization and evaluation of supercritical geothermal resources in Tohoku District , Japan
Keywords:supercritical geothermal, seismic activity, volcanic activity
Supercritical geothermal resources could be evaluated in terms of present volcanic activities, thermal structure, dimension of hydrothermal circulation, properties of fracture system, depth of heat source, depth of brittle factures zone, dimension of geothermal reservoir.
On the basis of the GIS, potential of supercritical geothermal resources could be characterized into the following four categories. 1. Promising: surface manifestation d shallow high temperature, 2 Probability: high geothermal gradient, 3 Possibility: Aseismic zone which indicates an existence of melt, 4 Potentia : low velocity zone which indicates magma input.
