Earthquake catalogs, referenced catalogs, velocity models, station list, and the SMART-2 network dataset for the 2024 Mw 7.4 Hualien earthquake sequence in Eastern Taiwan

This repository contains the primary earthquake catalogs, referenced catalogs, velocity models, station list, and the SMART-2 network dataset used in the analysis of the 2024 Mw 7.4 Hualien earthquake sequence in Eastern Taiwan, as presented in Yang et al. (2025). The primary earthquake catalogs and its derived results are located in the "/Catalogs/AutoQuake" directory and cover the time from 1 April 2024 to 28 April 2024. This includes the relocated catalog ("relocated_catalog.csv"), polarity-based focal mechanism catalog ("gafocal_catalog.csv"), phase picks generated by PhaseNet ("phasenet_picks.csv"), associated phase picks generated by GaMMA, ("gamma_picks.csv"), phase picks with polarity ("polarity_picks.csv"), and the initial catalog generated by GaMMA ("gamma_events.csv"). Referenced catalogs are also included: the initial Central Weather Administration (CWA) catalog downloaded on 29 April 2024 ("/Catalogs/CWA/initial_cwa_catalog_0429.csv"), a refined CWA catalog covering the same study period ("/Catalogs/CWA/refined_cwa_catalog.csv"), relocated events around the Longitudinal Valley region from Huang and Wang (2022) ("/Catalogs/Huang_and_Wang_2022/relocated_LV_events.csv"), and the catalog used for focal mechanism comparison ("/Catalogs/Focal_comparison/focal_comparison"). The 1D and 3D velocity model (Huang et al., 2014) used in this study are provided in "Hualien_1D.vel" and "tomops_H14". The station list is provided in "stations.csv". Poles and Zeros files and Seismic waveform data from the SMART-2 network (Chiu et al., 1994) collected between 1 April 2024 and 28 April 2024 are included in the "/SM_data" directory.本仓库包含用于分析2024年台湾东部Mw 7.4花莲地震序列的核心地震目录、参考目录、速度模型、台站列表以及SMART-2台网（SMART-2 network）数据集，相关研究成果已发表于Yang等人（2025）的工作中。核心地震目录及其衍生结果存放于"/Catalogs/AutoQuake"目录下，时间覆盖范围为2024年4月1日至2024年4月28日，包含：重定位地震目录（relocated_catalog.csv）、基于极化的震源机制目录（gafocal_catalog.csv）、由PhaseNet（PhaseNet）生成的震相拾取（phase picks）结果（phasenet_picks.csv）、由GaMMA（GaMMA）生成的关联震相拾取结果（gamma_picks.csv）、带极化信息的震相拾取结果（polarity_picks.csv），以及由GaMMA生成的初始事件目录（gamma_events.csv）。 本数据集同时收录多套参考目录：2024年4月29日下载的中央气象署（Central Weather Administration, CWA）初始目录（"/Catalogs/CWA/initial_cwa_catalog_0429.csv"）、覆盖同一研究时段的精修版CWA目录（"/Catalogs/CWA/refined_cwa_catalog.csv"）、Huang与Wang（2022）提出的纵谷区域周边重定位事件目录（"/Catalogs/Huang_and_Wang_2022/relocated_LV_events.csv"），以及用于震源机制对比的目录（"/Catalogs/Focal_comparison/focal_comparison"）。 本研究使用的一维与三维速度模型（Huang et al., 2014）分别存放于"Hualien_1D.vel"和"tomops_H14"文件中。台站列表存放于"stations.csv"文件。此外，2024年4月1日至2024年4月28日期间采集的SMART-2台网（Chiu et al., 1994）的极点-零点文件与地震波形数据，均存放于"/SM_data"目录下。
