It was located at sea 45 kilometers northwest of Southwest Maluku and at a depth of 210 kilometers The strongest shock, MMI scale VI, was felt in Tiakur, the regency’s capital.

The tremor was also felt in Tepa, a village on Babar Island, Southwest Maluku at MMI scale V and in Saumlaki of Tanimbar Islands at MMI scale IV. A weaker intensity was recorded in Tual of Maluku Province at scale III and in Sorong and Raja Ampat of West Papua at scale II.
