Moderate magnitude 4.0 quake hits 36 miles southeast of Homer, Alaska, United States around noon

An earthquake of magnitude 4.0 occurred around noon on Wednesday, July 16th, 2025, at 1:12 pm local time near Homer, Kenai Peninsula, Alaska, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at an intermediate depth of 64 miles. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 4.0 as well.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Halibut Cove (pop. 76, 27 miles away), Homer (pop. 5,500, 36 miles away), Fritz Creek (pop. 1,900, 37 miles away), Diamond Ridge (pop. 1,200, 38 miles away), and Anchor Point (pop. 1,900, 49 miles away), the quake was probably not felt.
