Description

The Location Tower is one of the three sites from the 3d seismic network originally installed in the 80’s which is recently re-established and enabled for real-time monitoring and recording acceleration data. The Location Tower is consisted of one surface and three downhole instruments up to 125 meters down the bedrock; a nine story building with two instruments installed on 6th and 9th storey & 4 instruments installed at the foundation level. In the period of 2021-2022 several small to moderate earthquakes have been recorded with the system. This study presents selected results and comparisons of equivalent linear analysis of the site using real recorded acceleration data. The soil profile is defined based on number of geophysical and geotechnical investigations at the location, both in-situ and laboratory tests. Obtained results are good starting point for further non linear site response analysis at the location which can be validated with stronger recorded earthquakes in future.
