If you felt one

- 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
