Daryono, the head of the agency's earthquake and tsunami center who like many Indonesians goes by one name, said the tremor was followed by 10 aftershocks, the largest with a magnitude of 5.3.
He tweeted the quake was "triggered by (a) rock deformation in the Maluku Sea Plate".
The initial quake was felt as far away as the city of Gorontalo in northern Sulawesi, where it shook houses, and the provincial capital, Manado.
