| Abstract | Cycles of the pressure observed during 1995-2002 years in the monitoring well of the two-phase fractured Verkhne-Mutnovsky (Kamchatka, Russia) geothermal reservoir shows 0.9-2.1 10-3 Hz frequency range (8-18 min time periods) and 0.2-0.4 bars of amplitude as a dominant cycling parameters. Some earthquakes adjacent to East Kamchatka Volcanic Zone associated with fluid pressure perturbations in two-phase Verkhne-Mutnovsky reservoir: each earthquake may associate its specific pressure perturbation in the form of change cycling parameters (time period and amplitude). The possible models of the pressure cycling in two-phase fractured geothermal reservoir discussed. |
