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
The USGS provides access to many different data and analytical tools that are useful for understanding the water-resource data that we collect. These tools allow the public, state and local governments and utilities, and other Federal agencies to view and understand the quality, quantity, distribution, and movement of surface and underground waters in New Jersey.
