The quake had a shallow depth of 49 km (30 mi) and was not felt (or at least not reported so).Quake Data | Interactive map | Seismograms | User reports | Aftershocks | Earlier quakes here | Quakes in Tonga | Vava'u | Ha'apai | NiuasHint: Click on the image to see different maps of this quake!Strong magnitude 5.4 earthquake at 49 km depth8 Sep 12:07 UTC: First to report: EMSC after 16 minutes.Update Tue, 8 Sep 2026, 12:09Magnitude 5.4 earthquake strikes near Neiafu, Vava'u, TongaA magnitude 5.4 earthquake near Neiafu, Vava'u, Tonga, was reported only 18 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a moderately shallow depth of 49. km beneath the epicenter after midnight on Wednesday, September 9th, 2026, at 12:51 am local time. 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.Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.Weak shaking might have been felt in Leimatu'a (pop. 1,400) located 37 km from the epicenter, Longomapu (pop. 570) 38 km away, Ta'anea (pop. 650) 40 km away, and Neiafu (pop. 3,800) 42 km away.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 25 km2 (10 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 9 km (5 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 9, 2026 12:51 am (Tongatapu)19 minutes ago5.449 km0 km - This quakeSouth Pacific Ocean, 42 km NW of Neiafu, Vava'u, TongaMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 25.6 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.2 quakes per year (or 1 quake every 5 years)Mag. 5 or higher: 4.4 quakes per yearMag. 4 or higher: 25.6 quakes per yearMag. 3 or higher: 39 quakes per year (or 3.3 quakes per month)Mag. 2 or higher: 39.1 quakes per year (or 3.3 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 25 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
