Moderate magnitude 4.5 earthquake at 153 km depth21 Sep 14:04 UTC: First to report: RaspberryShake after 6 minutes.21 Sep 14:04: Now using data updates from BMKG21 Sep 14:05: Magnitude recalculated from 4.4 to 4.5.Update Mon, 21 Sep 2026, 14:06Moderate 4.5 quake hits near Mulia, Puncak Jaya Regency, Central Papua, IndonesiaIndonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 4.5 quake in Indonesia near Mulia, Puncak Jaya Regency, Central Papua, only 8 minutes ago. The earthquake hit late at night on Monday, September 21st, 2026, at 10:58 pm local time at an intermediate to considerable depth of 153. 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.A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.5 earthquake as well.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Mulia (pop. 35,900) located 50 km from the epicenter, Tiom (pop. 21,300) 57 km away, Kenyam (pop. 6,400) 65 km away, Karubaga (pop. 6,700) 72 km away, and Wamena (pop. 41,800) 105 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)Sep 21, 2026 10:58 pm (Jayapura)12 minutes ago4.5153 km0 km - This quakeKabupaten Nduga, South Papua, 50 km S of Mulia, 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 16.8 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.03 quakes per year (or 1 quake every 31.3 years)Mag. 5 or higher: 0.72 quakes per year (or 1 quake every 1.4 years)Mag. 4 or higher: 9.5 quakes per yearMag. 3 or higher: 16.8 quakes per yearMag. 2 or higher: 17 quakes per yearThe area where this quake occurred has a high level of seismic activity. It has had at least 4 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 30 to 35 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
