EGS Collab Experiment 1: 3D Seismic Velocity Model and Updated Microseismic Catalog from Double-Difference Seismic Tomography

Description

This package contains a 3D Seismic velocity model and an updated microseismic catalog obtained for a double-difference seismic tomography study. The 3D_seismic_velocity_model text file contains x (m), y(m), z(m), P-wave velocity (km/s), P-wave velocity quality indicator (1 for well-constrained; 0 for poorly constrained), S-wave velocity (km/s), and S-wave velocity quality indicator (1 for well-constrained; 0 for poorly constrained). The Updated_MEQ_catalog text file contains event origin time, x(m), y(m), z(m), error in x (m), error in y (m), error in z (m), and RMS misfit (millisecond). The 3D_seismic_P-wave_velocity_model animation file shows slices of the 3D P-wave velocity model. The 3D_seismic_S-wave_velocity_model animation file shows slices of the 3D S-wave velocity model. The Interactive_MEQ_location_comparison HTML file is an interactive visualization of the updated microseismic event locations and the original seismic catalog. The visualization allows users to view and compare the event locations by dragging, rotating, and zooming in. An updated version of 3D_seismic_velocity_model and associated animations were included, which were calculated with a more strict assumption for quality indicators.

8 This file is an update of "3D Seismic Velocity Model". The P- and S-wave velocities are the same as those in "3D Seismic Velocity Model". The quality indicators were calculated with a more strict assumption. The file contains x (m), y(m), z(m), P-wave velocity (km/s), P-wave velocity quality indicator (1 for well-constrained; 0 for poorly constrained), S-wave velocity (km/s), and S-wave velocity quality indicator (1 for well-constrained; 0 for poorly constrained). https://gdr.openei.org/files/1228/3D_seismic_velocity_model_updated.csv
21 An interactive visualization of the original and updated microseismic event locations. The visualization allows users to view and compare the event locations by dragging, rotating, and zooming in the right part. The viewpoint of left part of the visualization will match that of the right part automatically. The left part cannot be dragged, rotated or zoomed. Click a legend will switch the clicked symbols between visible and invisible. https://gdr.openei.org/files/1228/Interactive_MEQ_location_comparison.html
