Strong magnitude 5.1 earthquake at 23 km depth17 Jul 01:16 UTC: First to report: USGS after 5 minutes.17 Jul 01:19: Magnitude recalculated from 5.0 to 5.1. Hypocenter depth recalculated from 36.00 to 22.90 km (from 22 to 14.2 mi). Epicenter location corrected by 7.8 km (4.8 mi) towards WNW.Update Thu, 17 Jul 2025, 01:18Significant magnitude 5.0 quake hits 59 miles southeast of Sand Point, Alaska, United States early afternoonA moderately shallow magnitude 5.0 earthquake was reported early afternoon near Sand Point, Aleutians East, Alaska, USA.According to the United States Geological Survey, the quake hit on Wednesday, July 16th, 2025, at 2:12 pm local time at a moderately shallow depth of 22 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.Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 5.0 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 Sand Point (pop. 1,100) 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.

of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!I didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report! Other users would love to hear about it!If you did NOT feel the quake although you were in the area, please report it as well! Your contribution is valuable to earthquake science and seismic hazard analysis.Compare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

It has had at least 6 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 3 hours after a magnitude 5.2 earthquake had hit on Wednesday, Jul 16, 2025, at 11:10 am (GMT -11 local time) in 16.4 km (10 mi) distance to the southeast:Mag. 5.2 earthquake 66 mi south of Sand Point - Alaska, United States - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 8.2.
