• Nanometrics Posthole Seismometer World-class Performance

    | Presentation/Poster

    The Nanometrics Trillium 120 Posthole (Trillium Posthole) seismometer is designed for subsurface installation to optimize seismic performance while minimizing the cost and logistics of site setup. This paper features an analysis of installation techniques in typical environments, and for each of these environments, provides compelling results from independent and internal studies that illustrate the advantages of buried instruments such as the Trillium Posthole.
