LOS ANGELES — A catastrophic 7.8-magnitude earthquake struck Southern California at 2:14 AM PST this morning, sending shockwaves through the Los Angeles coastline and triggering an immediate tsunami warning for the entire Pacific Coast. The US Geological Survey confirmed the epicenter was just 12 miles off the Long Beach shore, with tremors felt as far as San Diego and Sacramento. Emergency services report widespread structural collapse in downtown Los Angeles, with the historic Federal Building reduced to rubble and the Los Angeles Convention Center completely destroyed.

As the shaking subsided, rescue crews reported over 1,200 people missing in the hardest-hit areas of Long Beach and Compton. Mayor Karen Bass activated the state of emergency declaration as helicopters dropped supplies to stranded residents and firefighters battled raging fires ignited by ruptured gas lines. Multiple hospitals reported critical overcrowding, with trauma centers receiving patients with severe crush injuries and severed limbs.

The tsunami warning, which remains in effect as of 9:15 AM PST, has caused mandatory evacuations for 200,000 coastal residents. The Pacific Tsunami Warning Center confirmed a 15-foot wave hit Seal Beach at 4:03 AM, inundating downtown areas and causing additional structural damage.
