Moderate magnitude 4.4 earthquake at 27 km depth31 Dec 02:19 UTC: First to report: BMKG after 5 minutes.31 Dec 02:23: Magnitude recalculated from 4.6 to 4.4. Hypocenter depth recalculated from 10.00 to 27.00 km (from 6.2 to 16.8 mi). Epicenter location corrected by 12 km (7.6 mi) towards E.Update Wed, 31 Dec 2025, 02:21Moderate magnitude 4.6 quake hits 100 km southwest of Banda Aceh, Indonesia in the morningAn earthquake of magnitude 4.6 occurred in the morning on Wednesday, December 31st, 2025, at 8:13 am local time near Banda Aceh, Kota Banda Aceh, Nanggroe Aceh Darussalam Province, Indonesia, as reported by Indonesia's Meteorology, Climatology, and Geophysical Agency.According to preliminary data, the quake was located at a shallow depth of 10. km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.6 earthquake as well.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Banda Aceh (pop. 255,000) located 100 km from the epicenter.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)Dec 31, 2025 08:13 am (GMT +6)22 minutes ago4.427 km0 km - This quakeIndian Ocean, 93 km SW of Banda Aceh, 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 42 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 12.7 years)Mag. 5 or higher: 6.2 quakes per yearMag. 4 or higher: 18 quakes per yearMag. 3 or higher: 36.2 quakes per year (or 3 quakes per month)Mag. 2 or higher: 46 quakes per year (or 3.9 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 weeks after a magnitude 4.9 earthquake had hit on Wednesday, Dec 10, 2025, at 02:42 pm (GMT +7 local time) in 88 km (55 mi) distance to the northwest:Mag. 4.9 earthquake Indian Ocean - 104 km west of Pulau Breueh Island, Indonesia - Dec 10, 2025 - This was also the strongest quake in this area in at least 10 years.
