2019 Ambon Aftershocks Catalogue Data Compiled Using Local and Regional Seismic Networks

These Datasets present earthquake catalogs of the 2019 Ambon aftershocks compiled from the regional seismic networks of the Agency for Meteorology, Climatology, and Geophysics of Indonesia (BMKG) and the local network deployed by Institut Teknologi Bandung (ITB), Indonesian National Agency for Disaster Management (BNPB) and BMKG. The final earthquake catalogs are comprised of 1,009 and 1,764 aftershocks compiled from the regional and local network, respectively, which span the period of October 18th to December 15th, 2019. The range of their spatial region is -3.70o to -3.30o on the latitude and 128.15o to 128.60o on the longitude. Additionally, focal mechanism solutions of the main Mw 6.5 and its biggest triggered aftershock Mw 5.2 events were acquired. Such datasets could provide a basis for further seismology analysis, including seismic tomography, and source mechanism analysis, as well as further seismic hazard analysis in the Ambon and Seram islands. This dataset with its linked article is a companion for an article in the Tectonophysics with the title “Source Mechanism and Triggered Large Aftershocks of the Mw 6.5 Ambon, Indonesia Earthquake” (Sahara et. al., review process).本数据集包含2019年安汶余震的两套地震目录，数据源自印度尼西亚气象、气候和地球物理局（Agency for Meteorology, Climatology, and Geophysics of Indonesia, BMKG）的区域地震台网，以及由万隆理工学院（Institut Teknologi Bandung, ITB）、印度尼西亚国家防灾局（Indonesian National Agency for Disaster Management, BNPB）与BMKG联合布设的本地地震台网。最终的两套地震目录分别包含由区域台网和本地台网整理得到的1009次与1764次余震，时间跨度为2019年10月18日至12月15日。该数据集的空间覆盖范围为纬度-3.70°至-3.30°、经度128.15°至128.60°。此外，本数据集还包含主震（Mw 6.5）及其最大触发余震（Mw 5.2）的震源机制解。该数据集可为后续地震学研究提供基础支撑，涵盖地震层析成像、震源机制分析，以及安汶岛与斯兰岛地区的地震危险性分析等方向。本数据集及其关联文章为发表于《构造物理学》（Tectonophysics）的题为"Source Mechanism and Triggered Large Aftershocks of the Mw 6.5 Ambon, Indonesia Earthquake"（Sahara et. al., 审稿中）的论文配套数据。
