This repository provides Python scripts and example input files for the identification and analysis of repeating earthquakes (repeaters), with emphasis on hypocenter-repeaters and centroid-repeaters. It includes tools for hypocenter/centroid-repeater identification, nearest neighbor testing, circular statistics analysis, and rupture similarity index (RSI) analysis. The files included are listed below: RepeaterCatalog.xlsx: Repeater catalog identified using an assumed stress drop of 38 MPa, used for circular statistics analysis and RSI calculation. Input_sequence.xlsx: Example input file for nearest neighbor test (NNT) and hypocenter/centroid-repeater analysis. HypocenterRepeater_Identification.py: Script for identifying hypocenter-repeaters, defined here as co-located large and small earthquake pairs (CLSEPs). CentroidRepeater_Identification.py: Script for centroid-repeater identification. NNT.py: Script for nearest neighbor test (NNT). Circular_Statistics_Analysis_with_MC.py: Script for circular statistics analysis. RSI_analysis_with_MC.py: Script for rupture similarity index (RSI) analysis. These scripts were developed to support the analysis of rupture repeatability and spatial characteristics of repeating earthquakes.
