FDSN Network Information

FDSN code YB (2017-2017) Operated by University of Nevada (UNR Reno)
Network name Yosemite Valley Deep Refraction Microtremor (YOSREMI) Deployment region United States
Start date Aug. 7, 2017 End date Aug. 14, 2017
Short description

A Univ. of Nevada Applied Geophysics class will install four to eight 30-element refraction microtremor arrays 1 to 10 km long on the floor of Yosemite Valley, California. Recording of microtremor noise such as traffic will take place during daylight hours between March 19 and 22, 2017. The shear-velocity cross sections resulting from interpretation by the students will show the depth to basement and constrain the geometry of the aquifer below the Valley, informing water-supply, flooding, and pollution-control models being developed by the Park Service.
