Abstract
The main result of the 7 years’ continuous radon recording at the mineral spring “Radonquelle”, Bad Brambach was the identification of a “sensitive” epicentral area 12 km E of the measuring site (Heinicke et al., 1995a, b; Koch and Heinicke, 1996). The derived model conception is based upon a fluidal connection (water, mantle-originated gases) between the hypocenters and the observed spring, and a spreading of seismotectonically induced pressure pulse within the fluidal system. From January 6 to January 20, 1997 a radon anomaly with a maximum on January 12 was recorded at the “Radonquelle”. About 55 hours after that maximum an earthquake swarm with more than 100 single events occurred. The epicenter was located again within the above-mentioned sensitive region near Novy Kostel (Czech Republic). An increased gas flow in the spring capture was proved to be responsible for the generation of that anomaly, and confirmed the significance of the pressure pulse model.
