This article presents earthquake catalogs of the 2019 Ambon aftershocks compiled from regional the Agency for Meteorology, Climatology, and Geophysics of Indonesia (BMKG) and local seismic networks deployed in [1]. The final earthquake catalogs are comprised of 1009 and 1764 aftershocks compiled from regional [2] and local network [1], 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 128.15-128.60o 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, source mechanism analysis, and further seismic hazard analysis in the Ambon and Seram islands. This paper and its dataset are a companion for a published article in the Tectonophysics under the title "Source Mechanism and Triggered Large Aftershocks of the Mw 6.5 Ambon, Indonesia Earthquake" [1].
