Magnitude 2.6 earthquake strikes near Ontario, San Bernardino County, California, USA

An earthquake of magnitude 2.6 occurred early morning on Saturday, May 2nd, 2026, at 3:10 am local time near Ontario, San Bernardino County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 2.8 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 2.6 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 2.5.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ontario (pop. 171,200) located 4 miles from the epicenter, Eastvale (pop. 59,000) 4 miles away, Chino (pop. 85,600) 5 miles away, Rancho Cucamonga (pop. 175,200) 6 miles away, Upland (pop. 76,400) 6 miles away, and Pomona (pop. 153,300) 9 miles away. In Fontana (pop. 212,700, 10 miles away), Corona (pop. 164,200, 10 miles away), and Anaheim (pop. 350,700, 23 miles away), the quake was probably not felt.
