The quake's epicenter was located at 0.59-degree southern latitude and 128.06-degree eastern longitude, some 62 km northeast of Labuha, North Maluku, and at a depth of 10 km below sea level, according to information on the website of the Meteorology, Climatology, and Geophysics Agency (BMKG) on Sunday.
Inhabitants of Labuha coastal area, the capital of South Halmahera District, rushed towards higher grounds when the tremor occurred as they feared a tsunami.
Muslim Pora, a local resident of Labuha, said he felt the earthquake strongly, and his home's windows shuttered.
Kustoro, head of the Ternate meteorology, climatology, and geophysics office, said that the earthquake did not have the potential to trigger a consequent tsunami.
