Moderate magnitude 4.5 earthquake at unknown depth5 Jul 20:33 UTC: First to report: BMKG after 7 minutes.Update Sat, 5 Jul 2025, 20:36Moderate magnitude 4.5 quake hits 25 km northwest of Sabang, Indonesia early morningIndonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 4.5 quake in Indonesia near Sabang, Kota Sabang, Nanggroe Aceh Darussalam Province, only 10 minutes ago. The earthquake hit early morning on Sunday, July 6th, 2025, at 3:26 am local time at a shallow depth of 10. 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.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 Sabang (pop. 42,100) located 25 km from the epicenter, and Banda Aceh (pop. 255,000) 56 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 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)Jul 6, 2025 03:26 am (Pontianak)15 minutes ago4.510 km0 km - This quakeAndaman Sea, 29 km NW of Pulau We Island, IndonesiaMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 39.5 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.08 quakes per year (or 1 quake every 12.5 years)Mag. 5 or higher: 2.8 quakes per yearMag. 4 or higher: 11.4 quakes per yearMag. 3 or higher: 28.8 quakes per yearMag. 2 or higher: 41 quakes per year (or 3.4 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 10 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 3 minutes after a magnitude 4.6 earthquake had hit on Sunday, Jul 6, 2025, at 03:23 am local time (Asia/Pontianak GMT +7) in 23 km (15 mi) distance to the north:Mag. 4.6 earthquake Andaman Sea - 42 km northwest of Sabang, Indonesia - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 5.4.
