Text Supplement for ScholarWorks@UA collection Seismic moment tensor catalog for crustal earthquakes in the Cook Inlet and Susitna region of southern Alaska Vipul Silwal Version 1: May 3, 2018 Attribution: If you use these files, please cite Silwal et al. (2018) and Silwal (2018). Description of files This collection is established for the submission of a manuscript (Silwal et al., 2018). Three catalogs of seismic moment tensors were generated using first-motion polarities, body waves, and surface waves. The best solution (M 0 ) was obtained through a grid-search in the moment tensor space using the ‘cut-and-paste’ (CAP) approach, which allows for different fre- quencies and time shifts on different portions of seismograms (Silwal and Tape , 2016; Zhao and Helmberger , 1994; Zhu and Helmberger , 1996; Zhu and Ben-Zion , 2013). The moment tensor approach was adapted and applied in Silwal and Tape (2016) for double couple moment tensors and in Alvizuri and Tape (2016) for full moment tensors. (Silwal et al., 2018) updated the misfit function to take into account the polarity error. Alvizuri et al. (2018) applied the updated misfit function for estimation of full moment tensors and uncertainty. A summary of files in the collection is listed in the following table: figure description file name Figure A1 Waveform fits for 9 events around Beluga beluga cap.pdf Figure A2 Waveform fits for 22 events in Cook Inlet basin cookinlet cap.pdf Figure A3 Waveform fits for 22 events in Susitna basin susitna cap.pdf Figure B1 Moment tensor beachballs with input polarity for 9 events around Beluga beluga beach cap.pdf Figure B2 Moment tensor beachballs with input polarity for 22 events in Cook Inlet basin cookinlet beach cap.pdf Figure B3 Moment tensor beachballs with input polarity for 22 events in Susitna basin susitna beach cap.pdf – text file catalog of moment tensors sakmt mech.txt – zipped set of text files of input parameters for moment tensor inversions sakmt weights.zip – this file: summary of collection sakmt scholarworks.pdf Within each set of figures (A1, A2, A3, B1, B2, B3), the events are in chronological order by origin time. Figures A1, A2, A3: Waveform fits Waveform fits for 53 moment tensor inversions in south-central Alaska. Black are observed waveforms; red are synthetic waveforms computed using a frequency-wavenumber method (Zhu and Rivera , 2002) that assumes a (1D) layered model. The waveforms are fit separately within five time windows: P wave vertical component (PV), P wave radial component (PR), Rayleigh 1 brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by ScholarWorks@UA
