Moderate magnitude 4.7 earthquake at 61 km depth23 Mar 02:22 UTC: First to report: BMKG after 6 minutes.23 Mar 02:26: Magnitude recalculated from 4.4 to 4.7. Hypocenter depth recalculated from 54.00 to 61.00 km (from 34 to 38 mi). Epicenter location corrected by 7.8 km (4.8 mi) towards N.Update Mon, 23 Mar 2026, 02:27Magnitude 4.7 earthquake strikes near Tambolaka, Southwest Sumba Regency, East Nusa Tenggara, IndonesiaIndonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 4.7 quake in Indonesia near Tambolaka, Southwest Sumba Regency, East Nusa Tenggara, only 10 minutes ago. The earthquake hit in the morning on Monday, March 23rd, 2026, at 10:16 am local time at a moderately shallow depth of 61. km. 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 4.4.Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.Weak shaking might have been felt in Tambolaka (pop. 35,800) located 51 km from the epicenter.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Sape (pop. 5,000) located 78 km from the epicenter, Dompu (pop. 55,000) 88 km away, and Bima (pop. 161,400) 88 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 5 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Mar 23, 2026 10:16 am (GMT +8)16 minutes ago4.761 km0 km - This quakeSelat Sumba, 51 km W of Tambolaka, IndonesiaMain 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 395 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.12 quakes per year (or 1 quake every 8.3 years)Mag. 5 or higher: 2.8 quakes per yearMag. 4 or higher: 43 quakes per year (or 3.5 quakes per month)Mag. 3 or higher: 174 quakes per year (or 14.5 quakes per month)Mag. 2 or higher: 389 quakes per year (or 32.4 quakes per month)Mag. 1 or higher: 395 quakes per year (or 32.9 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 15 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 earthquakeThe earthquake occurred 7 days after a magnitude 4.9 earthquake had hit on Monday, Mar 16, 2026, at 07:41 pm (GMT +8 local time) in 75 km (47 mi) distance to the west:Mag. 4.9 earthquake Indian Ocean - West Nusa Tenggara, Indonesia - Mar 16, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 6.2.
