Seismograms

 

Recent seismic data from the STS-2 seismometer (distributed through SZGRF Erlangen, Germany).

 

pdf

 

Seismometer broad-band data: overlay of collocated STS-1 onto STS2 and vice versa. Ideally these should match perfectly.

 

 

 

 

Long-period data from collocated STS-1 and STS2 seismometers.

GPS at BFO

 

Notice: the GPS antenna including the radome underwent a phase calibration by Geo++ in Hannover. For this reason no data is available from 5.5.2008 - 18.6.2008. Mail us if you are interested in the phase calibrations for the analysis of the GPS data.

 

The RINEX data from BFO can be obtained from the ftp server of the BKG.
