Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Continuous, real-time monitoring occurs at some sites and periodic monitoring occurs at others; the most recent measurements are provided online for a few of our monitoring sites. Graphs showing the most recent data are updated regularly with update cycles ranging from 15 minutes to 24 hours. Updates may be interrupted occasionally by instrument, computer, or network malfunctions.

Landslide monitoring data and information provided on this website are preliminary and have not been reviewed for accuracy; therefore the data are subject to revision.
