Your search - The data set was downloaded and processed using python and the seismological community scientific library obspy (Krischer 2015). The figures were produced using Python and MATLAB and the Python module basemap was used to produce the map. The facilities of IRIS Data ervices, and specifically the IRIS Data Management Center, were used for access to waveforms, related metadata, and/or derived products used in this study.
