Catalog and DAS Data for the figures in the paper entitled "A Hybrid Earthquake Detection Method for Distributed Acoustic Sensing Array Data and Its Application to the 2022 Menyuan Earthquake Sequence"

File: cata_QHNC.csv The earthquake catalog provided by the Qinghai Earthquake Agency (QHNC) for the 2022 Menyuan earthquake sequence. This catalog spans the period from the mainshock on 2022-01-07 until 2022-02-28. This dataset serves as the official reference catalog for comparison and validation in the accompanying manuscript. File: cata_DAS.csv The composite event catalog derived from the Distributed Acoustic Sensing (DAS) array analysis, spanning the operational period from 2022-01-12 to 2022-01-16. This file combines events from the QHNC catalog with events detected using the Hybrid Earthquake Detection Method (ADE-HAT) proposed in the manuscript. The catalog includes columns that describe the detection status of each event: | detected? | yes | The QHNC catalog event was successfully detected by the Array Beam Detection (ABD) method alone. | | detected? | no | The QHNC catalog event was undetected by the ABD method alone. | | detected? | new | A newly detected event identified by the DAS array (ABD or TMF), not present in the QHNC catalog. | | detected? | new1 | An event visually observed (visible) on the DAS record that was not reported by QHNC and was undetected by the ADE-HAT method. | | moveout_multi | yes / no | Indicates whether the event was successfully detected by the Template Matched Filtering (TMF) component of the ADE-HAT method. | File: fig*.npz (Example) Description: Raw Distributed Acoustic Sensing (DAS) waveform data. The file is saved in NumPy (.npz) format and can be loaded using the numpy library. Each row in the array represents the time series for a single DAS channel. Sampling Rate: 100 Hz文件：cata_QHNC.csv 本数据集为青海省地震局（Qinghai Earthquake Agency, QHNC）提供的2022年门源地震序列地震目录，时间跨度覆盖2022年1月7日主震至2022年2月28日。本数据集作为配套手稿中对比与验证工作的官方参考目录。 文件：cata_DAS.csv 本数据集为经分布式声波传感（Distributed Acoustic Sensing, DAS）阵列分析得到的复合事件目录，运行监测时段为2022年1月12日至2022年1月16日。该文件整合了QHNC地震目录中的事件，以及本手稿提出的混合地震检测方法（ADE-HAT）所探测到的事件。 本目录包含用于描述各事件检测状态的字段： | detected? | 取值 | 说明 | | --- | --- | --- | | detected? | yes | 该QHNC目录事件仅通过阵列波束检测（Array Beam Detection, ABD）方法即可成功探测 | | detected? | no | 该QHNC目录事件无法仅通过阵列波束检测方法探测 | | detected? | new | 由DAS阵列（阵列波束检测或模板匹配滤波（Template Matched Filtering, TMF））新探测到的事件，未收录于QHNC目录 | | detected? | new1 | 在DAS记录上目视可观测到的事件，未被QHNC收录且未被ADE-HAT方法检测到 | | moveout_multi | yes / no | 标记该事件是否被ADE-HAT方法中的模板匹配滤波组件成功探测 | 文件：fig*.npz（示例） 说明：原始分布式声波传感（DAS）波形数据。该文件以NumPy压缩格式（.npz）存储，可通过NumPy库加载。数组中的每一行对应单个DAS通道的时间序列。 采样率：100 Hz
