Turn right toward the Foam Lab, the Center for Neotectonic Studies, and the LMR Bldg.

The UNR Seismological Laboratory maintains a network of over 100 sensors spread across Nevada and eastern California, to detect and locate earthquakes. Usually, earthquake locations and magnitudes are estimated using computerized analysis of digitized data from these sensors. However, this analog helicorder display provides an effective backup in case of computer failures, as well as an immediate and very visual indicator of earthquake activity for public viewing.
