A magnitude 5.0 earthquake struck the waters off the North Maluku provincial capital Ternate on Sunday morning but there was no immediate report of casualties or material damage. The quake was centered seven kilometers west of Ternate at a depth of 90 km, ANTARA quoted the Meteorology, Climatology and Geophysics Agency (BMKG) as saying in its website.
