Application of Travel-Time Seismic Tomography for Archaeological Studies of Building Foundations and Basements

The applicability of the travel-time seismic tomography algorithm with the adaptive environment parameterization for the engineering and archaeological studies is investigated. The investigation object is the environment under the ruins of the St. Onuphrius Church at the Big Solovetsky Island. Experimental geometry for the tomography studies is designed and the data are acquired and processed. The goal is to study in detail the church basement and underlying geological environment structure that can not be recovered with other geophysical methods. The synthetic experiments are performed using the standard checkerboard tests with the cells of 2, 3, and 4 m in size in order to estimate the adequacy of the results obtained. The recovered three-dimensional velocity pattern is in a good agreement with the data on the church and archaeological information.
