Since the St. Gallen public utilities company (Sankt Galler Stadtwerke) ended the testing and stimulation measures last Friday and the situation in the borehole stabilized, seismic activity around the borehole has remained stable at a low level (see diagram to left). Although the situation has now calmed down, further microearthquakes are expected and larger quakes cannot be ruled out. Initial estimates suggest it could be more than a year before seismic activity returns to the natural level previously observed. The strength and frequency of the quakes is set to diminish over time. The Swiss Seismological Service (SED) is currently analyzing seismic data from the last few days and will publish its latest findings here as they become available.
