CGPS in the Andes, northwest Argentina

We installed five continuous GPS stations in NW Argentina to measure crustal deformation across the Andean retroarc adjacent to the Puna plateau.  The goal of the proect is to improve our understanding of how crustal shortening in the retroarc fold and thrust belt contributes to the formation of high plateaux.

Crustal Deformation of Arizona

We are using GPS to detect crustal motions throughout Arizona.  Our goal is to determine how the crust is actively deforming.  The changes in crustal velocities that we seek to discriminate are very small (< 1 mm/yr) but have important implications for geodynamics and seismic hazards.

 

 


Continuous GPS in southern Dalmatia

Five continuous GPS monuments were installed during the summer of 2007 and a short semi-continuous occupation ran in early 2008.  The network will determine secular deformation rates for studies of the elastic strain rate field associated with ongoing Adria-Dinarides collision, and time dependent deformation associated with slow slip events on the Adria thrust décollement.

 

 

Central Highlands Iceland (CHIL) GPS

As of August 2008, the CHIL network has grown to 14 continuous GPS stations. CHIL forms a core component of a larger Iceland-wide CGPS network for tectonics.

Joshua Tree Integrative GPS Network JOIGN

 The goal of this project is to gain a better understanding of how strain is transferred from the southern San Andreas fault system to the eastern California shear zone.
