LOCAL SEISMIC OBSERVATIONS AT STATIONS NOVY-KOSTEL AND SKALNA, AND THEIR ITERPRETATION - PERIOD 1986-93

Systematic observations of natural seismic activity in the West-Bohemi an earthquake-swarm region began at two autonomous seismological stati ons of the Geophysical Institute, the digital station Novy, Kostel (NK C) and the analogue station Skalna (SKC), in May 1986 and December 198 9, respectively. This paper presents the station data of NKC and SKC, the method of processing the records, and the database structure. It a lso includes the interpretation of observations made at these stations in the period 1986-1993. It was found that the seismic activity in th e West Bohemian region, in the Vogtland (Saxony) and NE Bavaria was co ntinuous. Between two strong earthquake swarms, the energy in this are a was released in the form of a large number of micro-earthquakes of a markedly swarm-like nature, mostly concentrated in six focal regions.
