Geophysical Institute of the ASCR

Observatories of the Geophysical Institute
Czech Regional Seismic Network (CRSN)
Seismological observations of the Geophysical Institute (GI) have a long tradition and form the basis
of its research. Numerous projects are based on using the data provided by the observatories of the GI.
The Geophysical Institute operated seven stations of the CRSN in 2004-2005: Průhonice (PRU, since
1957), Kašperské Hory (KHC, since 1961), Dobruška/Polom (DPC, since 1992), Nový Kostel (NKC,
since 1997), Úpice (UPC, since 1987), Panská Ves (PVCC, since 2003), Třešť (TREC, since 2005).
Digital data from all stations are transferred to the GI in real time by Internet. Software packages
Antelope and SeisComP are used for automated data acquisition and exchange. The GI is largely
involved in international data exchange with global data centers and a number of European national
data centers and observatories.
Virtual network of the GI consists at present of about 40 real-time seismological stations in central
and southern Europe. About 20 new stations have been added to the virtual network in 2004-2005 as
a result of broad international cooperation of the GI in the frame of EC project Meredian (2000-
2005). Improved reliability of the automated regional locations of the virtual network of the GI has
been achieved.
Seismological Data Center of the GI provides the following services:
• Automated near-real time data acquisition of continuous broadband and short-period seismic data
by Antelope and SeedLink software packages.
• Global data exchange of both seismic phase readings and digital records with major international
data centers (ISC, NEIC, IRIS, ORFEUS, EMSC) and a number of neighbouring observatories,
• Daily analysis of digital seismograms by Unix program Seismic Handler. Rapid location of strong
seismic events in Central Europe by program LocSat.
• Archiving of digital records: continuous records are stored on a large raid system and archived on
a tape robot device with a capacity of 2 TB.
• Compiling and publishing seismological catalogues and bulletins on the web, collection and
evaluation of macroseismic reports about earthquakes felt on the territory of the Czech Republic.
• Recent automated locations of the CRSN and live seismograms of selected stations are displayed
on the web pages of the GI (http://www.ig.cas.cz).
• Informing the public through TV and radio interviews and articles in press about prominent strong
earthquakes and strong regional events.
