A 7.4-magnitude earthquake struck in the Molucca Sea off Indonesia's Ternate island early Thursday, killing at least one person, Report informs via BBC.
The quake, which struck at 06:48 local time (22:48 GMT) at a depth of 35km, sparked tsunami warnings which have since been withdrawn.
A 70-year-old woman in North Sulawesi died after being crushed by building debris, and another person broke their leg after jumping off a building, Indonesia's national news agency Antara reported.
The Hawaii-based Pacific Tsunami Warning Center initially warned that tsunami waves less than 0.3m (1 ft) "were possible" along the coasts of Guam, Japan, Malaysia, Papua New Guinea, the Philippines and Taiwan. The tsunami alert was lifted after two hours.
The epicentre of the quake was roughly midway between Manado and Ternate.
At least two aftershocks, with magnitudes 5.5 and 5.2, followed the major quake, with authorities warning of more to come.
The national geological agency reported "damage to buildings and injuries" about an hour after the initial tremor, but did not provide further details.
