A 7.4-magnitude earthquake struck in the Molucca Sea off Indonesia's Ternate island early Thursday, killing at least one person. 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quake, which struck at 06:48 local time (22:48 GMT) at a depth of 35km, sparked tsunami warnings which have since been withdrawn.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. While the region experiences high levels of seismic activity, some residents told the BBC this was one of the strongest earthquakes they have felt in at least the past six years. 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, but lifted the alert after two hours. Journalist Isvara Safitri, who lives in central Manado, recalled how furniture in her room shook for several seconds. 'It was really strong... My head even felt dizzy,' Safitri told BBC Indonesian. Residents described chaotic scenes as tremors caused panic in markets and schools. The epicenter of the quake was roughly midway between Manado and Ternate and was followed by aftershocks of magnitudes 5.5 and 5.2. Authorities reported damage to buildings and injuries across the affected areas. Video footage showed residents and officials walking through the rubble in Manado, with significant destruction evident at local establishments.
