FDSN Network Information

FDSN code ZD (2010-2013) Operated by University of North Carolina at Chapel Hill (UNC)
Network name PerU Lithosphere and Slab Experiment (PULSE/UNC) Deployment region United States
Start date Jan. 1, 2010 End date Dec. 31, 2013
Short description

This project will use bb seismology to image the crust, mantle, lithosphere, downgoing plate and sub slab mantle beneath south central Peru in order to improve the understanding of flat slab subduction.
