- 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)

From the QuakeIndex catalogue, built from the USGS FDSN event service · within 50 km of the centre above. Shaking is an estimate for the centre from magnitude, depth and distance, with the intensity equation USGS Did You Feel It? uses (Atkinson & Wald, 2007), on the Modified Mercalli scale. Ground conditions change it locally; it is a description of the past, not a hazard rating.
