Granite Dells Terrestrial Laser Scanning Dataset

Precariously balanced rocks (PBRs) are pedestal rocks that are used as negative indicators for earthquake-generated strong ground motions to physically validate seismic hazard analyses. To help understand the geologic and geomorphic settings in which PBRs form, terrestrial laser scanning was used to scan a small population of PBRs that are preserved on hillslopes adjacent to a small stream channel.

摇摇欲坠的平衡岩石（PBRs）作为地震产生的强地面运动的负指示器，被用于对地震危险分析进行物理验证。为了理解PBRs形成的地质和地貌环境，研究人员采用了地面激光扫描技术，对位于小溪流域附近山坡上保存的少量PBRs进行了扫描，以助于对该类岩石的地质和地貌背景有更深入的认识。
