Seismic activity in the Czech Republic in 2008

Abstract

The Czech Regional Seismological Network (CRSN), consisting of fourteen permanent digital broadband stations and two data centres, recorded and detected 9073 seismic events from all epicentral distances in 2008. Most of these events were located by the Czech Seismological Service, and many of them were analyzed in detail. This paper provides basic information on the configuration of the CRSN, routine data processing, seismicity in the Czech Republic in 2008 as well as macroseismic observations collected in 2008. The seismic activity on the territory of the Czech Republic and surrounding regions has been traditionally reported in annual bulletins published on the web sites of the Institute of Geophysics of the Academy of Sciences of the Czech Republic, Prague (http://www.ig.cas.cz), and in reports issued by the Institute of Physics of the Earth of Masaryk University, Brno (http://www.ipe.muni.cz). The bulletins however include events from local to teleseismic distances which makes the search for regional information complicated. The aim of this paper is to provide a quick overview of earthquakes and mining-induced seismic events which originated in the Czech Republic in 2008. The overview follows the contribution to the seismic activity in 2007 (Zednik and Pazdirkova, 2009). Earthquakes and mining-induced events in the Bohemian Massif in 19951999 were discussed by Zednik et al. (2001). A similar paper covering the seismicity in the period 20002006 is in preparation.
