Seismohydrological effects related to the NW Bohemia earthquake swarms of 2000 and 2008: Similarities and distinctions

▶ 20 years seismohydrological investigations at Bad Brambach (Vogtland, Germany). ▶ For the first time, semi-quantitative comparison of two strong swarm earthquake series (2000 and 2008). ▶ Different migrations of the earthquake foci through time, horizontally and in depth. ▶ Fluid triggering not only the in earthquake initiating phases. ▶ Long-term gas flow increases at several gas outlets in the Vogtland/NW Bohemia region between 1998 and 2008 ▶ Systematic relationship between anomaly occurrence and seismic activity cannot be derived at present.
