A 4.8 earthquake struck Southern California just after midnight on Monday, waking up many people across the Yuma region. Residents reported feeling the shaking, with some describing it as a slight jerk followed by lighter shaking. The U.S. Geological Survey reported a series of earthquakes since the initial one, with some being felt throughout San Diego and the Yuma area. A geology professor at Arizona Western College explained that Yuma falls into a seismic wave zone due to its proximity to Southern California and its fault lines, allowing the area to feel the ripple effect from quakes miles away. Despite the shaking, no major injuries or damages were reported in the Yuma area.
