This dataset contains images of scanned analog seismograms for historical earthquakes. They belong to the old instrumentation of the following KNMI seismic stations in the Netherlands: De Bilt (DBN), Epen (ENN), Heerlen (HEE), Ravensbos (RSB), Witteveen (WIT) and Winterswijk (WTS). The different parts of the name of the images correspond to: station code, channel code, instrument code, time of the first minute of the seismogram, time of the end of the seismogram (approximate) and version number. The complete description of the stations, their instrumentation and the channel codes can be found in the following report: http://bibliotheek.knmi.nl/knmipubTR/TR245.pdf
