Strong magnitude 5.3 earthquake at 29 km depth17 Jul 02:16 UTC: First to report: USGS after 7 minutes.17 Jul 02:19: Magnitude recalculated from 5.3 to 5.2. Hypocenter depth recalculated from 36.00 to 23.60 km (from 22 to 14.7 mi). Epicenter location corrected by 10 km (6.2 mi) towards S.17 Jul 02:29: Magnitude recalculated from 5.2 to 5.3. Hypocenter depth recalculated from 23.60 to 29.35 km (from 14.7 to 18.2 mi). Epicenter location corrected by 10.5 km (6.5 mi) towards WNW.Update Thu, 17 Jul 2025, 02:18Significant 5.3 quake hits near Sand Point, Aleutians East, Alaska, USAAn earthquake of magnitude 5.3 occurred early evening on Wednesday, July 16th, 2025, at 6:09 pm local time near Sand Point, Aleutians East, Alaska, USA, as reported by the United States Geological Survey.According to preliminary data, the quake was located 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 5.3 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 56 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.
