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).
