Moderate magnitude 4.5 earthquake at 322 km depth28 Feb 04:22 UTC: First to report: RaspberryShake after 6 minutes.28 Feb 04:22: Now using data updates from BMKG28 Feb 04:24: Magnitude recalculated from 4.8 to 4.5. Hypocenter depth recalculated from 344.00 to 322.00 km (from 214 to 200 mi). Epicenter location corrected by 10.9 km (6.8 mi) towards WNW.Update Sat, 28 Feb 2026, 04:24Moderate 4.8 quake hits near Tahuna, Kabupaten Kepulauan Sangihe, Sulawesi Utara, IndonesiaA very deep magnitude 4.8 earthquake was reported around noon near Tahuna, Kabupaten Kepulauan Sangihe, Sulawesi Utara, Indonesia.According to Indonesia's Meteorology, Climatology, and Geophysical Agency, the quake hit on Saturday, February 28th, 2026, at 12:15 pm local time at a great depth of 344. km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 4.5.According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Tahuna (pop. 35,300, 103 km away), the quake was probably not felt.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Feb 28, 2026 12:15 pm (GMT +8)13 minutes ago4.5322 km0 km - This quakeCelebes Sea, 112 km W of Tahuna, IndonesiaMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 18.6 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)Mag. 6 or higher: 0.13 quakes per year (or 1 quake every 7.9 years)Mag. 5 or higher: 0.81 quakes per year (or 1 quake every 1.2 years)Mag. 4 or higher: 10.6 quakes per yearMag. 3 or higher: 18 quakes per yearMag. 2 or higher: 19.2 quakes per yearThe area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 4 weeks after a magnitude 4.8 earthquake had hit on Saturday, Jan 31, 2026, at 08:36 am (GMT +8 local time) in 28 km (17 mi) distance to the west:Mag. 4.8 earthquake Celebes Sea - 140 km west of Tahuna, Indonesia - Jan 31, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.2.
