Latitude: 50.8428 N

Longitude: 16.2931 E

Elevation: 353 m

Depth of vault: 42 m

Seismometer type: STS-2

Data acquisition system: MK6

Recording (broadband): continuous digital three component at 20 Hz sampling
rate
 
Recording (short period): triggered digital three component at 100 s.p.s.

In operation since: March 13, 1997 (broadband), 1992-2009 (short period,
GS-13 and MK2 data acquisition system).
Observatory exists since 1970. BB-13 seismometers and MK-5 acquisition
system used for broadband prior to December,1999.

Site description: The sensors are installed in special casings on a concrete
stope in a World War II tunnel of an unfinished underground factory, 42
meters below ground level, in Lower Carboniferous graywack-type rocks.
The site offers excellent geological conditions for seismic registration,
yet it experiences occasional noise from local industry located in 
Swiebodzice, 2 km away, Walbrzych, 8 km, and Swidnica, 15 km. The station
records also mining induced seismic events from Lubin Copper Basin and 
Upper Silesian Coal Basin as well as numerous blasts from Lower Silesian
quarries.

Data processing: Station transmits data by internet to Warsaw, where it
is disseminated and archived. Station performs on-site data analysis.
Observatory runs a continuous analogue
recording on paper of both broadband and short period. Papers are stored
on site.

History: Observatory was created in 1970 in connection with the development
of Lubin Copper Basin at about 80 km distance. Various types of analogue
instruments were used in the 1970s, 1980s and into the 1990s. Most of
those old instruments have been taken down in the late 1990s.
