Dubrovnik historic buildings being continuously measured for earthquakes in new project

Written by  May 13, 2022

As part of the scientific research project "Seismic risk assessment of cultural heritage buildings in Croatia - SeisRICHerCRO", funded by the Croatian Science Foundation, a seismograph for continuous measurement of ambient vibrations and potential earthquakes was installed in the building of the City Hall of Dubrovnik.

The purpose of the measurement is to continuously observe the dynamic properties of the City Hall building in order to identify possible changes in fundamental frequencies that could be affected by an earthquake or vibration caused by human activity and accordingly assess the potential risk. Measurements will be carried out until the end of the project, which ends in January 2025.

This project focuses on characteristic buildings and groups of cultural heritage sites in potentially seismically endangered areas, with risk assessment becoming a strategic tool when it is necessary to set priorities in case of restoration.

The old town of Dubrovnik was selected for this research, which, in addition to the city administration building, includes churches, monasteries, the Rector's Palace, the Sponza Palace and all Dubrovnik museums, and the Cathedral of St. Jakov in Šibenik and Trakošćan Castle. The aim is to develop simple, applicable methodologies and practical procedures for seismic risk assessment of cultural heritage sites in order to, based on the assessed risk, strengthen the resilience of infrastructure and thus reduce potential risks of damage, economic and human losses.

The project is led by the Department of Geophysics, Faculty of Science, University of Zagreb, the project leader is Assoc. dr. sc. Snježana Markušić, and project associates doc. dr. sc. Davor Stanko and doctoral student Jakov Stanislav Uglešić.
