Once you drill a hole from the surface to this formation, you allow water to flow freely to the surface, and … WebTectonophysics August 12, 2015. Between 12 July 2008 and 18 January 2010 a seismic swarm occurred close to the town of Court-Saint-Etienne, 20 km SE of Brussels (Belgium). The Belgian network and a temporary seismic network covering the epicentral area established a seismic catalogue in which magnitude varies between ML -0.7 and ML 3.2.
