A tectonic earthquake struck the waters near Pulau Batang Dua, Ternate, in North Maluku early Tuesday morning. The seismic event occurred at 03:39:21 WIB on May 26, 2026.
Updated analysis indicates the earthquake reached a magnitude of M5.5. The epicenter was located at coordinates 1.13° N and 126.20° E, situated in the sea approximately 124 km southeast of Bitung, North Sulawesi, at a depth of 25 km.
Seismic Impact and Regional Effects
The tremor was caused by faulting activity within the Maluku Sea Plate. The source mechanism has been identified as a strike-slip movement.
The earthquake was felt across several regions, including Ternate, Manado, Bitung, North Minahasa, East Bolaang Mongondow, Tomohon, and Tondano. In these areas, the intensity reached III MMI, characterized by vibrations felt clearly inside homes, similar to the sensation of a passing truck.
Tsunami Risk and Future Monitoring
Despite the location of the epicenter in the sea, modeling confirms that the earthquake does not have the potential to trigger a tsunami.
As of 03:55 WIB, monitoring has not yet detected any aftershock activity. While no immediate aftershocks were recorded, seismic activity of this nature may require continued observation to ensure regional stability.
