The accompanying zip-files includes raw waveform data for all earthquakes and the file merged_nor.out includes all manual phase onset picks of all earthquakes. The file stations.txt includes the geographical coordinates of seismic stations. All data in the zipped files may be processed and used with the SEISAN seismology software.
