A 7.4-magnitude earthquake struck the Molucca Sea off Indonesia's Ternate island early Thursday, resulting in at least one confirmed death. The tremor occurred at 06:48 local time at a depth of 35km, causing widespread panic across North Sulawesi and North Maluku. Local authorities reported that the quake triggered immediate tsunami warnings that were later withdrawn.
Impact on North Sulawesi and Ternate
Indonesia's national news agency Antara reported that a 70-year-old woman died in North Sulawesi after being crushed by falling building debris. Another individual suffered a broken leg after jumping from a building during the shaking. In Manado, search and rescue teams documented significant damage at a sports complex where metallic structures were bent and furniture was displaced.
Residents in the region described the event as one of the most severe tremors in recent years. In the city of Bitung, power outages affected several stores as people fled into the streets. Parents rushed to local schools near the coast to evacuate children amid chaotic scenes.
"It was really strong... My head even felt dizzy," said journalist Isvara Safitri to BBC Indonesian, noting that the roads outside her home were visibly shaking.
Regional Tsunami Alerts and Seismic Risks
The Hawaii-based Pacific Tsunami Warning Center initially warned that tsunami waves under 0.3m were possible along the coasts of Japan, Malaysia, the Philippines, Taiwan, Papua New Guinea, and Guam. These alerts remained in place for two hours before officials determined there was no significant threat. The epicenter was located roughly midway between the cities of Manado and Ternate.
Indonesia sits atop the Pacific Ring of Fire, a zone characterized by frequent tectonic activity and volcanic eruptions. While the region is accustomed to seismic events, the scale of this 7.4-magnitude quake exceeds the intensity of most tremors felt by locals in the last six years. This event underscores the persistent vulnerability of Indonesia's coastal infrastructure to high-magnitude events.
Aftershocks and Infrastructure Recovery
Following the primary quake, the national geological agency recorded at least two aftershocks with magnitudes of 5.5 and 5.2. Officials have warned that further tremors are likely as the tectonic plates stabilize. Hospitals in Manado reported frantic evacuations, with staff establishing makeshift treatment areas in open spaces and vehicles to ensure patient safety.
Economic recovery will depend on the extent of the structural damage to commercial hubs in North Sulawesi. Authorities are currently assessing the full scale of the building losses and infrastructure failures. Investors and regional planners will likely focus on reinforcing coastal defenses and building codes to mitigate future seismic risks.
