A city in California’s Inland Empire; county seat of Riverside County
Multiple wildfires are spreading across Southern California, triggering dozens of evacuation orders and warnings. The Sandy Fire near Simi Valley is about 15% contained at roughly 1,700 acres, while the Bain and Verona fires in Riverside County have prompted widespread evacuations as firefighters fight steep terrain and shifting winds.
Recent studies show California’s San Andreas and San Jacinto faults are under stress at levels not seen in a millennium, raising the risk of a large, multi-fault rupture. Cajon Pass could act as a bridge or barrier, and preparedness measures are urged as hazard models improve with physics-based simulations.
