FDSN code YB (2017-2017) Operated by
Network name Yosemite Valley Deep Refraction Microtremor (YOSREMI) Deployment region United States of America
Start year 2017 End year 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.
