A magnitude 5.2 earthquake near Nikolski, Aleutians West, Alaska, USA, was reported only 18 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a shallow depth of 6.2 miles beneath the epicenter after midnight on Tuesday, September 16th, 2025, at 12:02 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.2 earthquake as well. Other agencies reporting the same quake include France’s Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.1, the citizen-seismograph network of RaspberryShake at magnitude 5.2, and the German Research Centre for Geosciences (GFZ) at magnitude 5.2.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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.
