Short summary
This paper provides infrasound data analysis, modeling, and interpretation of the source characteristics of the 28 September 2018 magnitude 7.5 Sulawesi earthquake. Epicentral ground movement by the earthquake rupture as well as the secondary shaking of nearby mountainous topography is responsible for the strong infrasound generated. Findings allow one to improve knowledge of infrasonic and seismoacoustic source processes and the monitoring capabilities of the infrasound arrays used.
