On 16 June 2021, a moderate earthquake with Mw 5.9 occurred in the Banda Sea, precisely at the top of the Banda Arc. The fault plane mechanism in this area is still not well identified, and this problem can be solved by determining the activated fault plane. In this research, the activated fault plane was based on the estimation of rupture directivity of the earthquake using the curve fitting method between observed and calculated P-wave rupture duration data. The maximum epicentral distance between the station and the epicentre of the earthquake is 40°. The number of seismic stations used is 33 stations with good azimuthal coverage. The rupture directivity of the earthquake is towards the south-southwest (SSW) with an azimuth of 196.5° ± 3.3°. This research has activated fault plane results validated using five aftershocks epicentres from USGS and NP1 CMT catalogue from GEOFON. The consistent NP is NP1 with strike/dip/slip values, respectively as follows 217/57/-85. This research also revealed that the earthquake located at the top of the Band Arc had an SSW-NNE fault orientation.
