A magnitude 4.3 earthquake occurred early Tuesday morning, September 29, 2026, at 3:36 a.m. local time near Ferndale, Humboldt County, California, USA, according to the United States Geological Survey.
According to preliminary data, the quake occurred at a very shallow depth of 1.4 miles. Shallow earthquakes are felt more strongly than deeper ones because they are closer to the surface. The exact magnitude, epicenter, and depth of the quake may be revised within the next few hours or minutes as seismologists review the data and refine their calculations, or as other agencies issue their reports.
Towns or cities near the epicenter where the quake may have been felt as very weak shaking include Ferndale (pop. 1,400), located 64 miles from the epicenter.
