Abstract

The Vogtland/Western Bohemia region is part of the Saxothuringian Earthquake Province. It is an isolated area of active intraplate seismicity. Observations of the seismicity between 1962 and 1998 are summarized. More than 17000 earthquakes have been detected microseismically with M L reaching from about −1.5 to 4.6. In the considered time interval, the catalogue of Vogtland events can be regarded as complete for magnitudes larger than 1.8. The region is well known for the occurrence of earthquakes clustered contemporarily in time and space. In this study, altogether 82 clusters are defined. Among them, clusters with swarm properties are distinguished from clusters with main shock accompanied by fore- and aftershocks, and from single events. 48 swarms are detected.

The magnitude-frequency distribution of the maximum magnitudes of the clusters is studied. In the magnitude range 1.8 ≤ M L ≤ 3.1, a bimodal character of the magnitude-frequency distribution is detected for both swarms and nonswarm-like events. The slope is greater for larger magnitudes than in the small-magnitude range. A gap in the magnitude-frequency distribution of clusters is observed for maximum magnitudes between 3.1 and 4.3. Furthermore, clusters themselves are characterized by the b-values of their magnitude-frequency distributions. Swarms show b-values greater than 0.7. Epicenters of swarms are confined to a few subregions. Epicenters of nonswarm-like events are distributed over a larger region than epicenters of swarms but hypocenters of swarms and nonswarm-like clusters may be located close to each other.

The envelope of the distribution of magnitudes as a function of time is investigated. In the considered time interval, a statistically significant recurrence of strong events of about 72 months is discovered by a frequency analysis. Comparing the seismicity between 1897 and 1908 with the seismicity between 1962 and 1998 temporal variations in the recurrence become obvious. The Nový Kostel zone is discussed in more detail. The average hypocenters of swarms are located on a SW-dipping fault segment that intersects the Eger Rift in NNW-SSE direction.

Discussing properties of the seismicity in the Vogtland/Western Bohemia region it is concluded that the increased seismicity may be explained by the presence of fluids on deep reaching faults. The occurrence of swarms, their variability as well as the small distances between hypocenters of swarms and nonswarm-like events point to strong lateral and possibly temporal changes of the properties of the fault system.
