Earthquakes are rare here
133 earthquakes of M1.5 or larger have been recorded in New Jersey in 10 years, and most weeks have none. There have been none in the last 7 days.
With so few, a QuakeIndex score — this week as a percentile of New Jersey's own weeks — would only say whether anything happened at all, so none is shown. That is a statement about New Jersey, not about our data.

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.
