An earthquake of magnitude 5.2 occurred in the morning on Monday, December 15th, 2025, at 8:03 am local time near Adak, Aleutians West, Alaska, USA, as reported by the European-Mediterranean Seismological Centre (EMSC).
According to preliminary data, the quake was located at a moderately shallow depth of 28 miles. 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 5.2 earthquake as well. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.2.
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 Adak (pop. 330) located 31 miles from the epicenter.
