Earthquakes in the Czech Republic and surrounding regions in 1995-1999

In the time span from January 1995 to December 1999 the Czech National Seis mological Network (CNSN), consisting of ten permanent digital broadband sta tions, several local networks and two data centers, detected and recorded 9 530 regional natural seismic events, 27 greater than magnitude 2. Most of t hese events were located by, the Czech Seismological Service (CSS), and the most prominent of them were analyzed in detail. A large number of quarry b lasts were recorded as it-ell but were not included in the analysis. We pro vide basic information on the configuration of the CNSN and on the way of r outine data processing employed by the CSS in this paper. The over-all regi onal seismicity monitored by the CNSN in 1995-1999 is briefly, reviewed. Th e main results of observations and evaluation of the local (NW-Bohemia/Vogt land, South Bohemia, Sudeten) and induced (Kladno, Pribram, Upper Silesia, Lubin/Poland) seismic activity within this period are presented in a conden sed form. Finally, a summary, on macroseismic observations on the territory of the Czech Republic in 1995-1999 is also presented.
