Repeating earthquake waveforms in the North Anatolian Fault following the 1999 Izmit/Duzce earthquakes

This website contains the seismic waveforms of repeating clusters along the North Anatolian Fault following the 1999 Izmit/Duzce, Turkey earthquakes. After you extract the file (Turkey_Repeating_EQ_PBZ_2006.zip), you will find 40 directory named like "C40" to denote each cluster ID in the catalog I sent to you. In each directory, the waveforms are placed under each station directory like "VO" "FP". Finally the waveform name is like WF.1999323093632.e with the format stn.evid.chan. It is in the Seismic AnalysisCode (SAC) binary format. Please note that the data is somewhat processed with the waveform being shifted with the P arrival.But it is in its raw count unit (i.e., without removing instrument response). The station coordinate and other related information is stored in the SAC header.
