| Abstract | There are at least 30 high temperature geothermal systems (inferred reservoir temperature in Sumatra which transfer heat from crustal intrusions to the surface along the active Sumatra volcanic arc. Their position is controlled by the Sumatra Fault Zone, an active mega-shear zone which follows the median axis of the arc. Large, low temperature resources exist in the Tertiary sedimentary basins of East Sumatra where anomalously high thermal gradients (up to m) have been observed. |
