Exploration Basis

This study was done to analyze how earthquake faults redistribute stresses in the earths crust around geothermal areas.

Notes

Low angle aerial photos and field verification were used to identify fault ruptures. Redistribution stresses associated with recent fault ruptures were examined to evaluate how faulting processes affect geothermal areas. Average displacements on faults were measured and stresses were calculated using the Coulomb Failure Function. The models indicate that induced stress changes near the endpoints of recent fault ruptures seem to create ideal conditions for geothermal production.
