Key Developments
- Casualties and Damage: One fatality confirmed in Manado, North Sulawesi, due to building collapse, several others injured by falling debris.
- Seismic Data: Magnitude 7.4 quake occurred at 6:48 AM local time at a depth of 35 kilometers, centered 127 kilometers west-northwest of Ternate.
- Tsunami Impact: Coastal waves reached heights of 75 centimeters in North Minahasa and 30 centimeters in West Halmahera before the threat passed.
- Emergency Response: Tsunami warnings for Indonesia, the Philippines, and Malaysia were officially withdrawn after two hours of high-level alert.
- Aftershocks: Indonesia’s BMKG has recorded at least 11 aftershocks, with the strongest measuring magnitude 5.5.
The Molucca Sea region was struck by a severe 7.4 magnitude earthquake on Thursday, April 2, 2026, sending residents into a state of panic during the early morning hours. The U.S. Geological Survey (USGS) confirmed the tremor hit at a shallow depth of 35 kilometers. While the epicenter was located in the sea near Ternate, the most significant damage was reported in Manado, North Sulawesi.
Search and rescue officials in Manado confirmed that one person was killed after being buried under the rubble of a collapsed building. In addition to the fatality, reports of structural damage to government buildings and schools have emerged from the city. Witnesses described a terrifying minute of intense shaking that forced thousands of residents to flee their homes, many still in their pajamas, as the tremors persisted for over 60 seconds.

Tsunami Alert and Coastal Activity
Immediately following the quake, the Pacific Tsunami Warning Center (PTWC) issued a hazardous wave alert for coastal areas within a 1,000-kilometer radius. This placed the shorelines of Indonesia, the Philippines, and Malaysia on high alert. Local authorities in Ternate and the surrounding Spice Islands urged citizens to move to higher ground immediately.
Monitoring stations eventually recorded tsunami activity, though the waves remained below destructive levels. Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) reported waves of 75 centimeters in North Minahasa, while Bitung and West Halmahera saw surges of 20 to 30 centimeters. Approximately two hours after the initial strike, the PTWC lifted the warning, stating that the threat had passed, though officials warned residents to remain cautious of minor sea-level fluctuations.
Geological Context: The Ring of Fire
Indonesia’s position on the “Ring of Fire,” an arc of intense seismic activity where multiple tectonic plates collide, makes it one of the most disaster-prone nations on Earth. This latest event in the Molucca Sea is the result of complex interactions between the Australian and Pacific plates, a boundary that frequently generates high-magnitude tremors.
The region has a grim history of seismic disasters. In 2022, a 5.6 magnitude quake in Cianjur killed over 300 people, while the 2018 Sulawesi earthquake and subsequent tsunami claimed thousands of lives. Most notably, the 2004 Indian Ocean tsunami remains the deadliest in recorded history, killing 230,000 people across 14 countries. Authorities emphasize that while today’s tsunami alert has been lifted, the frequency of these events necessitates constant vigilance and modernized early-warning infrastructure.
