Earthquakes near nuclear plants
Every earthquake of magnitude 4.0 or greater that the US Geological Survey has located within 200 km of a nuclear power plant, for the past 30 days. A plant here means any site with a reactor in operation or under construction. The list is checked hourly.
This page reports distance, not damage. The figure is from the earthquake's epicentre to the plant's listed coordinates. It is not an estimate of shaking at the site, and nothing here says a reactor tripped, was inspected or changed its output. The NRC feed on US daily status carries no cause for a power reduction, so the two are deliberately not connected.

What this does not cover
The USGS catalogue is complete for earthquakes of roughly magnitude 4.5 and above worldwide. Smaller events appear only where a contributing seismic network reported them, so an absence of magnitude 4.0 to 4.5 events outside well-instrumented regions is not evidence that none occurred. Magnitudes and locations are revised as the USGS reviews an event, and an event the USGS later deletes is removed from this list on the next hourly check. Plant coordinates come from the tracker and vary in precision.
