January 2022 Arthur River M 4.8 Earthquake - Recorded by Perth DAS cable

These are the data files (SAC) of the Arthur River 24 January 2022, 21:24:47 (UTC) earthquake. Each SAC file contains coordinate information of the sensing point with duration minimum expected P wave arrival time - 20s (tp is uniform for all channels). The data was downsampled to 100 Hz. \nLineage: Data was produced via connecting CSIRO owned iDAS v2 DAS interrogator to the unused telecom cables located in the AARC building - Level 1, Kensington, WA.本数据集为2022年1月24日世界协调时21时24分47秒阿瑟河地震的SAC数据文件（SAC）。每个SAC文件均包含传感点的坐标信息，其数据时长覆盖最小预期P波初至时间前20秒的时段，且所有通道的P波初至时间（tp）均保持一致。该数据已被降采样至100赫兹。 数据溯源：本次数据集通过将澳大利亚联邦科学与工业研究组织（CSIRO）所拥有的iDAS v2型分布式声学传感（DAS）解调仪连接至西澳大利亚州肯辛顿AARC大楼1层的闲置电信电缆生成。
