Filename: 2024_East_Asia_Data.tar.gz Short description: Seismic data are provided for 3 earthquakes (see Supplemental Table 1 in Festin et al. 2024) for earthquake 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. Radial component seismograms are given that are windowed in time around the SKS 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 BHR or HHR for broadband radial or highgain radial component seismogram sac = file format (seismic analysis code) In total: 2,210 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: All of the earthquakes occurred in Southeast Asia and were recorded in N. America. All events were collected as a part of the following work: Thorne, M.S., Pachhai, S., Leng, K., Wicks, J.K., and Nissen-Meyer, T. (2020) New candidate ultralow-velocity zone locations from highly anomalous SPdKS waveforms, Minerals, 10 , 1-26, https://doi.org/10.3390/min10030211. Data collection is described in this paper. 2.
