Determination of Shear-Wave Velocity to 30 m Depth from Refraction Microtremor Arrays (Remi-Test). Applied in Some Greek-Roman Archaeological Sites in Alexandria, Egypt
Abstract
Preservation of monuments all around the world and increasing their stability against earthquakes is a matter of great importance. Main purpose of the present study is to investigate the dynamic characteristics of the underground monuments at the ancient sites in Alexandria, Egypt (Catacomb of Kom El-Shoqafa, El-Shatbi Necropolis, and Necropolis of Mustafa Kamil, Amd El-Sawari site (Serapium and ancient library)) and identify the main damage mechanism, in order to evaluate the risk of structure damage or collapse in case of future events using microtremors recordings. Array measurements at three sites in the city of Alexandria were performed to estimate the Vs velocity of soil/rock formations for site effect analysis. Our study includes a detailed geological and geotechnical survey of the areas, measurement, analysis and interpretation of ambient noise data using the refraction microtremor (ReMi) method.
