Southern California experienced a series of earthquakes, with the largest measuring 4.4 in magnitude, striking near Fontana and felt widely across Los Angeles. The initial tremors were followed by several smaller quakes, including a noticeable 4.3 magnitude event that rattled San Bernardino and Riverside counties. Residents reported shaking throughout the region, with no significant damage immediately reported. The earthquakes come just a day after a tsunami advisory, adding to the concerns in the area. This sequence of seismic activity has left many residents on edge as they assess their surroundings.
