A magnitude 4.0 earthquake near Paso Robles, San Luis Obispo County, California, USA, was reported only 3 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 5.6 miles beneath the epicenter early morning on Thursday, August 14th, 2025, at 6:41 am local time. 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.
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 San Simeon (pop. 460) located 14 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Cambria (pop. 6,000) located 22 miles from the epicenter, King City (pop. 13,900) 30 miles away, Greenfield (pop. 17,200) 35 miles away, Paso Robles (pop. 27,200) 38
