Strong magnitude 5.0 earthquake at 15 km depth5 Mar 19:31 UTC: First to report: USGS after 6 minutes.5 Mar 19:36: Magnitude recalculated from 5.4 to 5.0. Hypocenter depth recalculated from 34.00 to 14.80 km (from 21 to 9.2 mi). Epicenter location corrected by 9.1 km (5.6 mi) towards W.Update Thu, 5 Mar 2026, 19:33Significant magnitude 5.4 earthquake 59 miles south of Nikolski, Alaska, United StatesAn earthquake of magnitude 5.4 occurred only 8 minutes ago 59 miles south of Nikolski, Alaska, United States, the United States Geological Survey reported.The quake hit at a moderately shallow depth of 21 miles beneath the epicenter near Nikolski, Aleutians West, Alaska, USA, in the morning on Thursday, March 5th, 2026, at 9:25 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.Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 5.4 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 59 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.

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 10 km2 (4 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)Mar 5, 2026 09:25 am (GMT -10)14 minutes ago5.015 km0 km - This quakeNorth Pacific Ocean, 63 mi SE of Chuginadak Island, Aleutians West Census Area, Alaska, United StatesMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeThe earthquake occurred 10 days after a magnitude 5.5 earthquake had hit on Monday, Feb 23, 2026, at 12:02 am (GMT -10 local time) in 72 km (45 mi) distance to the northwest:Mag. 5.5 earthquake Bering Sea - Alaska, United States - Feb 23, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 6.8.
