Research Code and Repositories
This page lists selected research workflows, reproducible scripts, and external tools relevant to my work in earthquake seismology, induced seismicity, waveform processing, clock-drift correction, and seismic imaging. Some project-specific codes are available upon request because they are linked to active collaborations and unpublished datasets.
Current Research Workflows
Ambient-noise cross-correlation and station timing inspection
Scripts for preparing station-pair tables, grouping dense/sparse arrays, computing daily ambient-noise cross-correlations, and checking station timing offsets through lag measurements and waveform residuals.
Dense-array earthquake detection, association, and relocation
Python-based workflows using waveform preprocessing, phase picking, association, catalog construction, and relative relocation for dense temporary seismic arrays in the Sichuan Basin and Longmenshan fault zone.
Induced seismicity and waveform-based fluid indicators
Analysis scripts for studying migration patterns, low-frequency waveforms, attenuation signatures, and seismicity evolution associated with hydraulic-fracturing operations in the Weiyuan shale gas field.
Useful Open-Source Codes
ObsPy
Python toolbox for reading seismic waveform data, MiniSEED/SAC processing, filtering, metadata handling, and waveform visualization. ObsPy GitHub repository
PhaseNet
Deep-learning phase picker used for high-throughput P- and S-wave arrival picking in dense seismic networks. PhaseNet GitHub repository
GaMMA
Earthquake phase association package useful for building earthquake catalogs from machine-learning picks. GaMMA GitHub repository
GMT

Legacy and Educational Codes
Finite-difference and earthquake-cycle examples
Selected external C/C++, MATLAB, and Python examples for wave propagation, finite elements, and earthquake-cycle modeling. These are useful for teaching and learning numerical seismology.
