The Interpacific Project - A Cooperative Exercise for Assessing Reliability and Accuracy of Seismic Methods

The InterPacific (Intercomparison of methods for site parameter and velocity profile characterization) project aims to assess the reliability/variability of seismic site characterization methods (borehole and surface wave methods) used for estimating shear wave velocity (Vs) profiles and corresponding lumped parameters (e.g., Vs,30). The ultimate goal of the project is to determine procedures that can be used for the construction of consistent ground models for seismic studies. Three sites have been selected in France and Italy for the implementation of the project. They are representative of different geological conditions relevant for the evaluation of seismic site response effects: a stiff rock outcrop, a deep soft deposit, and an intermediate case with thick stiff soils and large bedrock depth.
