Rio Grande Rift Crustal Deformation Measurements Using GPS
an NSF-Earthscope Project

--Frequently Asked Questions About the Rio Grande Rift--

Most of the network has finished recording and been decommissioned, but 11 sites are still logging data! Click here for a summary of the current status of the network!

The red triangles in the map below represent Rio Grande Rift network GPS station locations. If you want to know more about a particular site, click on a triangle below or the site link at right to get details.

The Goal Of This Project is to measure GPS motions in the Rio Grande Rift to address the following questions:

  • What controls extension within "narrow" continental rifts and how does rifting relate to lithospheric heterogeneity?
  • What earthquake hazard does the Rio Grande Rift pose?
  • Is deformation steady or episodic?
  • Does observed Quaternary fault slip agree with geodetic strain rates?
  • How wide is the rift, and how does strain vary along strike?
  • How far north has the Rio Grande Rift propagated?
  • How does rift propagation manifest in Neogene rotation of the Colorado Plateau?
  • What is the influence of mantle rheology, and how does deformation style depend on strain rate?
