TN214 Earthquake:Catalog:Microseismicity
Microseismicity catalog of westernmost Gofar transform fault, East Pacific Rise, 2008
This microseismicty catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data file is in ASCII text format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth, and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the paper "Seismicity, fault architecture, and slip mode of the westernmost Gofar transform fault" by Gong and Fan, 2022, JGR. The data set was generated as part of the projects called Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment; and, CAREER: Using seismic sources to probe megathrust fault conditions. The project was funded by NSF awards OCE-1833279 and EAR-2143413.
