Groundwater Response to Earthquakes

Did you know? Earthquakes can affect groundwater levels?

We often see a response to large (and sometimes not so large) earthquakes in groundwater levels in wells. The USGS maintains a network of wells for monitoring various things like natural variability in water levels and response to pumping and climate change across the U.S.

USGS Data Delivery Tools

USGS WaterAlert allows users to set notification thresholds for any USGS real-time data collection station, including stream, tidal, and groundwater gages, water-quality, and weather stations and sends emails or text messages to subscribers whenever the threshold conditions are met, as often as every hour.

Floods: Recurrence intervals and 100-year floods

How do we know or measure if a flood that could happen tomorrow is worse than one that happened 2, 10 or 50 years ago? If heavy rain is being forecasted does that mean that rivers are going to rise and spill over their banks and flood your neighborhood? These are some of the questions that many of us think about when flooding or heavy rain is forecast by the National Weather Service (NWS) or...

Hurricanes and Storm-Tide Monitoring

 

The USGS works in partnership with other federal agencies and state agencies to provide data about coastal flood hazards.  In New Jersey, the USGS operates a network of instruments along the coast and back bays to measure tide levels and other meteorological data for floodprone areas.   Scientific information about flood events and the development of tools to communicate...

Earthquake Resources

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.

Flood Resources

The USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late...

Landslide Monitoring and Research in the Atlantic Highlands area, New Jersey

Recent shallow landslides have occurred on the steep hillslopes of the Atlantic Highlands area during and after large storm events with exceptionally heavy rainfall. These shallow landslides have resulted in extensive damage to residential property and local infrastructure and threatened human safety.The USGS New Jersey Water Science Center (NJWSC) and the USGS Landslide Hazards...
