Fig. 1

a Active fault map of the northern Banda region adapted from Patria et al. (2021) shown by red lines. The epicenter of the historical earthquakes from NOAA (National Oceanic and Atmospheric Administration) from 1600 to before 1900 are presented as black stars. Centroid moment tensor solutions (navy beach balls) of events with depth < 20 km and a magnitude more than Mw 5 in the period of 1976–2018 are derived from Global CMT. b Map of the aftershock distributions (indicated by blue circles) in the study area derived from Sahara et al. (2021a; b) between October 18th to December 15th, 2019 recorded by local and BMKG regional networks. The epicenter of the mainshock is shown by a magenta star (Global CMT) and a red star (BMKG). Focal mechanism solutions from both agencies are inserted by red beach balls. Fault segments from Patria et al. (2021) are plotted in black lines. The area colored in orange represents the urban or populous region
