If you felt one
- Was that an earthquake? — checks what was recorded near you in the last hour
- Report what you felt to USGS — reports go to USGS, not to us, and they are what produces the intensity maps
- Expect aftershocks, and be ready to Drop, Cover, and Hold On if you feel one; if you are in a damaged building, go outside and move away from it (Ready.gov, FEMA; what to do during and after an earthquake)
- Near the coast, go inland or to higher ground as soon as strong shaking stops (Ready.gov); official warnings are on Tsunami.gov

Be ready
Earthquakes cannot be predicted, here or anywhere, so the useful step is the one taken beforehand. The advice below is from the agencies responsible for it.
- Ready.gov: earthquakes (FEMA) — what to do before, during and after, including Drop, Cover, and Hold On
- Build a kit (FEMA) — water, food and supplies for several days; our summary
- USGS: preparedness — the hazard behind the advice, from the agency that records every quake on this page
- The Great ShakeOut — the yearly earthquake drill, with material for homes, schools and workplaces
- ShakeAlert covers August, CA: alerts reach phones through Wireless Emergency Alerts and the MyShake app, seconds before shaking arrives
- Tsunami.gov (NOAA) — the official tsunami warnings for the coast; a quake page here never stands in for one
- California Earthquake Authority — retrofit grants and the state's not-for-profit earthquake insurance
