Seismicity rate evolution in a reservoir without control due to constant injection of fluids at Qs. 

From left to right: Fluid pressure distribution over the reservoir; Seismicity rate in region V2 (black) and in region V1 (orange). A seismicity rate equal to 1000 means that 1000 more earthquakes of a given magnitude in a given time window are expected.
