The earthquake occurred at a depth of 10 kilometres, with its epicentre at 8.25° south latitude and 120.42° east longitude. The epicentre was located offshore, north of Ruteng. The event was a shallow earthquake linked to activity on the Flores Back-Arc Thrust, and its source mechanism involved upward movement.
