An earthquake of magnitude 4.2 occurred after midnight on Saturday, July 18th, 2026, at 12:00 am local time near Akhiok, Kodiak Island, Alaska, USA, as reported by the United States Geological Survey.According to preliminary data, the quake was located at a very shallow depth of 3.1 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.0 earthquake.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Akhiok (pop. 72) located 61 miles from the epicenter.Earthquake data: Date & time: Jul 18, 2026 12:00 am (GMT -10) local time (18 Jul 2026 10:00 GMT)Magnitude: 4.2Depth: 5.00 kmEpicenter latitude / longitude: 56.21°N / 153.3°W (Alaska, United States)Primary data source: USGS
