Earthquake microseismicity catalog of the Gofar transform fault system at ~4.5°S, East Pacific Rise, 2020-2022

These microseismicity catalogs are derived from data retrieved from ocean-bottom seismometers deployed during 2020-2022 as part of the Gofar Transform Fault Earthquake Prediction Experiment. The data files are in ASCII format. The first row is a column header that describes the thirteen data columns of the catalogs: Eventid, Year, Month, Day, Hour, Minute, Second, Latitude, Longitude, Depth, ClustID, ClustSize, and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. The data set was generated as part of the projects called "Imaging Stress and Material Properties at the Gofar Transform Fault: Unraveling the Physical Controls on Fault Segmentation and Seismicity", "Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment" and "Tectono-magmatic Controls on the Origin and Evolution of Mid-Ocean Ridge Segmentation at Slow-to-Intermediate Spreading Rates - Top down or bottom up". Funding was provided by NSF awards OCE-2527242, OCE-1833279, OCE-1832830, OCE-1832868, OCE-1928776 and by NSERC Discovery Grant RGPIN-2024-05737.
