TN214 Earthquake:Catalog:Microseismicity
Earthquake microseismicity catalog of the Quebrada transform fault system at ~3.7°S, 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 files are in ASCII 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 "Microseismicity indicates atypical small-scale plate rotation at the Quebrada transform fault system, East Pacific Rise" by Gong et al., GRL. The data set was generated as part of the projects called Oceanic Transform Faulting: Foreshocks, Seismic and Aseismic Slip on the Quebrada, Discovery and Gofar Transforms; and, Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment. Funded was provided by NSF awards OCE 0242117 and OCE 1833279.
Device Info
The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
