Abstract
This catalog/dataset contains 60,006 seismic events between magnitude (Mw) -1.0 and 4.5. It was obtained using publicly available seismic data from 2000 through 2020. The catalog was generated using a workflow that includes new and established software for earthquake detection (Mousavi et al., 2020; Woollam et al., 2022), association (Zhang et al., 2019), location (Lomax et al., 2000, 2009) and magnitude estimation (Satriano, 2022). Events in the catalog are located near volcanoes, outlet glaciers, ice shelves, and within the continental interior. The catalog thus includes events from diverse source processes (cryospheric, volcanic, and tectonic). Preliminary observations include thousands of events near Mount Erebus, Ross Island, and the McMurdo Sound region, repeated seismic events at Ice Streams or large glaciers, and deep long period events in Marie Byrd Land Executive Committee Range. The file contains the latitude, longitude, depth, origin time, Magnitude, errors in the locations and the RMS. More details of the data set and all relevant methods can be found in Pena Castro et al., 2024.
