Earthquakes felt in New Jersey are generally few and small. However, some earthquakes have produced damage in New Jersey. New Jersey’s seismic hazard is lower than many earthquake-prone parts of the United States. Across the state, seismic hazards are highest in northeastern New Jersey.
USGS Earthquake Resources
The USGS implements the Earthquake Hazards Program (EHP) to research the causes and effects of earthquakes. Seismic hazard mapping produced by the USGS helps explain earthquake vulnerability of states and regions across the country. The USGS also operates the Advanced National Seismic System (ANSS) to monitor and report earthquake occurrences across the world.
