Refraction Microtremor (ReMi) Evaluations Services
FromNinyo & Moore
The refraction microtremor (RE/MI) technique utilizes Rayleigh waves. The technique can be employed with traditional seismic refraction to obtain engineering properties and simultaneously evaluate.

The data are collected by generating semi-random seismic energy along a linear array of geophones. Urban settings with a high degree of cultural noise including vehicular traffic and other seismic noise sources are ideal. The data are subjected to spectral analysis to derive detailed layer velocity information so that generalized engineering properties such as shear modulus and Poisson`s ratio can be calculated versus depth evaluated.
