Horizon is windows-executable software for analyzing the occurence, consequence, mitigation, and economics of seismically-induced soil liquefaction via CPT sensing and models. Salient features include:

  • CPT processing: Inverse filtering and interface correction; CPT sensor alignment via statistical cross-correlation.
  • Six triggering models; Four free-field manifestation models; Shallow-foundation fragility and vulnerability models.
  • Seamless integration with USGS probabilistic seismic hazard analysis (PSHA) framework; Compute return periods of free-field manifestation, foundation damage, and economic loss.
  • Cost-benefit analytics for deciding whether/how to mitigate liquefaction risks; Quantify value of planned or constructed mitigation activities, wherein improvement is detected and incorporated via changes to CPT sensing data.
