Company Performance Metrics
Terean develops software, hardware systems, and services for shear-wave seismic imaging and subsurface characterization. The company’s VsSurf 1dS and VsSurf 2dS software generate 1D and 2D S‑wave depth–velocity profiles from passive and active seismic data for site class determination, depth to bedrock, rippability, liquefaction assessment, and
fault and landslide imaging. Terean’s ēDAQ bundles combine multi‑channel seismographs, geophones, accessories, and VsSurf licenses for field data acquisition. The firm also offers on‑demand processing and plotting services, where in‑house geophysicists convert client seismic records into ASCE 7‑22 compliant analyses and reports. Its tools are used in geotechnics, engineering, mining, energy, water resources, and research to obtain subsurface information without extensive drilling.
