A magnitude 3.0 earthquake hit this afternoon, centered about 3 kilometers south-southwest of the San Francisco Zoo. It was shallow, brief, and just strong enough to make you pause mid-sentence and look at your coworker like, "Did you feel that?"

Residents across the western side of the city and down the peninsula reported the shake. "Felt a wiggle and small aftershock in outer sunset," noted one SF resident. Over in Pacifica, another local said they were "wondering if I was being crazy feeling something" — the eternal Bay Area earthquake experience in a single sentence. Daly City residents also confirmed the quick rattle.

The good news: a 3.0 is essentially the earth clearing its throat. No damage, no injuries, no dramatic footage for the national news to loop for 48 hours. Just a one-second reminder that we all live on a network of fault lines and collectively choose not to think about it.

The less fun news: San Francisco's earthquake preparedness infrastructure remains a perennial question mark. The city has spent years and considerable taxpayer dollars on seismic retrofit programs, and while a 3.0 tests nothing structurally, it's always a good moment to ask yourself the basics. Do you have an emergency kit? Do you know your building's soft-story retrofit status? Have you checked on that earthquake insurance policy you keep meaning to look into?

Small quakes are free reminders. The big one doesn't send a calendar invite. Use today's little shake as a nudge — check your supplies, review your plan, and maybe stop putting off that go-bag you've been "meaning to pack" since 2019.

Welcome to life on the San Andreas. Rent's high, the ground moves, and somehow we all stay anyway.
