An intermediate magnitude 5.1 earthquake was reported in the morning near Nikolski, Aleutians West, Alaska, USA.
According to the United States Geological Survey, the quake hit on Thursday, September 4th, 2025, at 10:01 am local time at an intermediate depth of 44 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 5.1 earthquake as well.
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 Nikolski (pop. 18) located 62 miles 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.
