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)
QuakeIndex does not issue warnings or forecasts. For earthquake early warning see ShakeAlert and the MyShake app.
