The United States Geological Survey reported a magnitude 3.8 earthquake in the United States near Chase, Matanuska-Susitna, Alaska, just 4 minutes ago. The earthquake struck after midnight on Saturday, October 17th, 2026, at 12:16 am local time, at an intermediate depth of 58 miles. The exact magnitude, epicenter, and depth of the earthquake may be revised over the next few hours or minutes as seismologists review the data and refine their calculations, or as other agencies issue their reports.Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC), which also listed the earthquake at magnitude 3.8.According to preliminary calculations, we do not expect that the earthquake was felt by many people or caused any damage. In Chase (pop. 34, 30 miles away), Talkeetna (pop. 880, 38 miles away), and Susitna North (pop. 1,300, 52 miles away), the earthquake was probably not felt.Earthquake data: Date & time: Oct 17, 2026 12:16 am (GMT -8) local time (17 Oct 2026 08:16 GMT)Magnitude: 3.8Hypocenter depth: 93.20 kmEpicenter coordinates: 62.85°N / 150.51°W (Matanuska-Susitna Borough, Alaska, United States)Primary data source: USGS
