        abstract = {Static stress drop of induced earthquakes is a parameter which re?ects the in?uence of induced seismicity on the
stress ?eld in reservoir rock. On the other hand, events occurrence time and localization depends on the previous
stress distribution in the rock mass. Therefore, we decided to use static stress drop to assign areas of relatively
higher probability of future event occurrence with respect to entire area of seismic activity. For analyses 354-event
group of earthquakes with spectral parameters determined using spectral ratio method from NW part of The
Geysers geothermal site was used. We analyzed distributions of interpolated stress drops, determined on the basis
of events from constant moving time window using biharmonic spline interpolation method, for chosen groups
and sequences of events. Some of the distributions reveal that events tend to occur in the areas of speci?c ranges
of interpolated stress drop values what indicates a potential for future use of static stress drop in seismic hazard
assessment.
