BREAKING: A catastrophic 7.8 magnitude earthquake has struck off the California coast, sending shockwaves through the Bay Area as tsunami warnings erupt. The US Geological Survey confirmed the epicenter 100 miles west of San Francisco at 3:45 PM PST, with the tremors lasting nearly 45 seconds. The quake—California's strongest in 50 years—has triggered a tsunami alert for all coastal communities from Santa Cruz to Monterey.

Eyewitness accounts flood in: 'The ground just opened up,' reported Maria Chen, a nurse in Oakland, 'I saw buildings sway like toys before collapsing.' Emergency responders describe 'complete gridlock' on I-80 with 20+ vehicles stuck in collapsed overpasses. Power outages now affect 70% of San Francisco and San Jose residents. The Golden Gate Bridge has been shut down indefinitely after structural damage was detected.

Critical updates: • The National Weather Service confirmed a 5-foot tsunami wave hit Monterey Bay 12 minutes post-quake • Emergency crews are responding to 15+ major building collapses in Oakland • State Governor declares 'Level 3 Disaster' across 4 counties • Crowdsourced reports show fire alarms activated in 300+ buildings • Coastal evacuation orders issued for all shoreline zones
