Science for a changing world
Introduction
The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

This is our main USGS Google+ account (what we typically like to refer to as the "bureau account").

Content and links to third-party sites do not constitute endorsement of those sites or their content by the U.S. Geological Survey and are meant for informational purposes only.

Comment Policy:

We welcome your comments and hope that our conversations here will be polite. You are responsible for the content of your comments.

We reserve the ability to delete any of the following:
  • violent, obscene, profane, hateful, or racist comments
  • comments that threaten or harm the reputation of any person or organization
  • advertisements or solicitations of any kind
  • comments that suggest or encourage illegal activity
  • off-topic posts or repetitive posts that are copied and pasted
  • personal information including, but not limited to, email addresses, telephone numbers, mailing addresses, or identification numbers
  • comments which may cause public panic or may falsely cite the deployment of emergency services (e.g., "major earthquake to strike Los Angeles in next 24 hours!").
In short: be nice, be mature, and add to the discussion. If you have any questions or comments about this policy, please email us.

Content that we can remove from our Page includes status updates, comments, mentions, cross-posts, or any other user-supplied content which is posted to this USGS Page, or any of it's modules or sections.

USGS Awards $4 Million to Support Earthquake Early Warning System in California and Pacific Northwest to support transitioning the “ShakeAlert” earthquake early warning system toward a production stage. A functioning early warning system can give people a precious few seconds to stop what they are doing and take precautions before the severe shaking waves from an earthquake arrive.

New England Maps Adding Trails: Several of the new US Topo quadrangles for New Hampshire and Vermont now display parts of the Appalachian National Scenic Trail (A.T.) and other selected public trails. Also, parts of the new maps for Connecticut and Massachusetts feature parts of the New England National Scenic Trail as well as A.T segments. Further, all of these revised New England maps, to include new US Topo maps for Rhode Island, highlight significant additions to the new quads such as map symbol redesign, enhanced railroad information and new road source data. http://on.doi.gov/1VPjtAo

Tupelo Thru Time: The US Topo map and Historical Topographic Map Collection websites have updated the interactive map application to those home pages. The new series features 10 topographic maps (and layer variants) of the Tupelo, Mississippi area. These maps and scans span more 122 years and some new trail data has been provided by the National Park Service and International Mountain Bike Association. These flash thumbnails of original scanned maps display all available versions of the Tupelo quadrangles in an animated format. The display allows the user to view the maps in chronological order, access larger version of the map and go directly to the free download services. http://1.usa.gov/jtRGVx, http://1.usa.gov/HgbHNw

New Magnolia State Maps Adding Trails: Several of the 772 new US Topo quadrangles for Mississippi now display parts of the Natchez Trace National Scenic Trail and other selected public trails. Further significant additions to the new quadrangles include map symbol redesign, enhanced railroad information and new road source data. For Gulf Coast residents, recreationalists and visitors who want to explore the featured Mississippi trails by biking, hiking, horseback or other means, the new trail features on the US Topo maps will be useful. http://on.doi.gov/1LPCVYW
