Icequake Catalog from Rutford Ice Stream, West Antarctica, January 2019 Cite as Lee, I., Alley, R., & Anandakrishnan, S. (2026) "Icequake Catalog from Rutford Ice Stream, West Antarctica, January 2019" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract This dataset contains a catalog of icequakes recorded near the grounding line of Rutford Ice Stream, West Antarctica, using an array of 29 seismic stations. The catalog covers the period from 4 to 26 January 2019. Icequake detection and location were performed using the QuakeMigrate software, with the search constrained to depths between 1200 and 2000 meters to target events near the ice-bed interface. The dataset is provided as a single CSV file.
