Seismological Station Průhonice - (PRU)


Station Průhonice (PRU) has been operating as an analogue reference station of the Geophysical Institute since 1957. The station was equipped with digital instrumentation Lennartz 5800 in 1991. Vistec datalogger was operational in the period 1997-2003. EarthData digitizer + SeisComP datalogger were installed in late 2003. The data are telemetered to the Interpretation Laboratory at the Geophysical Institute. PRU provides digital broad-band records of selected earthquakes for data centre ORFEUS in the Netherlands.
