Sulawesi quake shakes communities but no tsunami threat detected | World
A magnitude 5.7 earthquake struck the waters off North Sulawesi, Indonesia, at 1.56am WIB on Sunday, June 7, 2026. According to Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG), the shallow 10-kilometer-deep quake occurred approximately 124 kilometers southeast of Tutuyan in East Bolaang Mongondow Regency, though authorities confirmed no tsunami threat exists.
How strong was the shaking in North Sulawesi?
The tremors were felt across several districts, with varying intensity levels reported. The strongest impact occurred in Nuangan, East Bolaang Mongondow, where residents experienced tremors reaching Levels III to IV on the Modified Mercalli Intensity (MMI) scale.
In Motongkad (East Bolaang Mongondow) and Pinolosian Timur (South Bolaang Mongondow), the shaking was recorded at Level III intensity. BMKG defines Level III vibrations as being distinctly felt indoors, similar to a heavy vehicle passing by, while Level IV shaking can rattle windows, doors, and household items.
Why does the depth and location of this quake matter?
The earthquake originated at a shallow depth of only 10 kilometers. Shallow undersea quakes often cause more immediate surface shaking, which explains why residents in Bolaang Mongondow felt distinct tremors despite the epicenter being 124 kilometers southeast of Tutuyan.
BMKG used specific coordinates—0.26 degrees South latitude and 125.07 degrees East longitude—to model the event. This modeling allowed the agency to quickly determine that the seismic event posed no tsunami risk to coastal communities.
What may happen next in the region?
While monitoring stations had not detected any aftershocks as of 2.15am WIB, the situation remains under observation. It is possible that smaller seismic adjustments could occur as the crust stabilizes.
Residents may continue to receive alerts from BMKG. Authorities have urged the public to remain alert but avoid unnecessary panic as they monitor for any further activity.
