TLDR
- Following a M7.6 earthquake in the Maluku Sea on April 2, 2026, BMKG Manado recorded 1,770 aftershocks.
- Of these, 36 were felt by residents in North Sulawesi and North Maluku, with the largest aftershock measuring M5.8.
- BMKG forecasts the aftershock activity will stabilize within two to three weeks and advises the public to rely on official information.
The recent seismic activity in the Maluku Sea, triggered by a powerful M7.6 earthquake on April 2, 2026, has kept residents of North Sulawesi and North Maluku on edge. The Meteorology, Climatology, and Geophysics Agency (BMKG) Stasiun Geofisika Manado has meticulously documented the aftermath, recording a staggering 1,770 aftershocks. This persistent seismic unrest, while diminishing in frequency, serves as a potent reminder of the region's geological vulnerability.
The Meteorology, Climatology, and Geophysics Agency (BMKG) Stasiun Geofisika Manado recorded 1,770 aftershocks after the main M7.6 earthquake.
While the majority of these tremors were minor, 36 were strong enough to be felt by the local population, causing understandable anxiety. The largest of these, a magnitude M5.8 event, underscores the potential for continued disruption. BMKG's analysis points to the complex dynamics of the Maluku Sea Plate subduction zone as the cause, a familiar geological reality for this seismically active archipelago.
Of the total aftershocks, 36 earthquakes were felt by the public in the Batang Dua area, North Maluku.
From our perspective here in Indonesia, understanding and monitoring these seismic events is paramount. While international news might focus on the raw numbers, for us, it's about the immediate impact on communities, the preparedness measures being taken, and the reassurance provided by our national agency, BMKG. The agency's consistent communication, including forecasts for stabilization and clear advisories against misinformation, is crucial for maintaining public calm and trust. We are accustomed to living with the earth's movements, but each significant event reinforces the importance of preparedness and reliable information from trusted sources like BMKG.
The aftershock activity shows a fluctuating downward trend. BMKG estimates that the total decay time for aftershocks will last about two to three weeks until seismic conditions return to normal.
