Overview

This site is located at the 101/280 freeway interchange in San Jose at  37.3393, -121.8520 (approx 31m elevation). A single Granite unit records a surface Episensor and three downhole Hyposensors at 17, 42 and 91m. UCSB assisted in the downhole installations on 3/2/16. The deep hyposensor had a compass and was glass beaded in at 347.2o magnetic, within 1 degree of true-North, and the other two hyposensors were installed with loading-poles, rotated and aligned to true-North.
