DOI 10.7278/S5d-d24y-bqdz --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: PKP_PHILIPPINES_DATA_SHARE.tar.gz Seismic data are provided for 58 earthquakes (see Supplemental Table 1 in manuscript) for earthqauke parameters. Data for each earthquake are provided in their own directory. The naming convention for each directory is: yyyymmddhhmm i.e., the directory name is given in terms of event year, month, day, hour, and minute that the earthquake occurred. Within each directory the seismograms for that earthquake are stored in Seismic Analysis Code (SAC) format. Vertical component seismograms are given that are windowed in time around the PKIKP seismic arrival. The naming convention of each file is eventid.network.stationcode.component.sac eventid = the same ID as given above (yyyymmddhhmm) for the event network = the two letter seismic network code for the station stationcode = the seismic station abbreviation component = either BHZ or HHZ for broadband vertical or highgain vertical component seismogram sac = file format (seismic analysis code) In total: 24,848 individual seismic recordings are provided. 2. Relationship between files: NA 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Data collection is described in the manuscript associated with this data collection. 2. Methods for processing the data:
