Variation of the a fluid pressure in the well and b the injection rate with increasing stimulation time. The magnitude of the seismic events is indicated by red circles. In general, events with larger magnitudes are linked to fluid pressure drops in well, although a swarm of low-magnitude earthquakes is observed after pressure drops. Additionally, pressure drops are linked to peaks of the injection rate
