After the earthquakes in Zagreb and Petrinja in 2020, numerous churches, cultural and historical buildings built before 1964. throughout Northern Croatia suffered damage. Most of the damage includes damage to roofs, chimneys and unreinforced walls. Most of the injured of sacred buildings as well as cultural and older buildings in Northern Croatia was created on the prominent topographic localities - elevations.
The research was carried out in several stages:
- study of the macroseismic intensity map of the 2020 earthquake to detect potential topographic locations in search of damage that consequence of topographical effects
- study of the report on the inspection of statically damaged churches caused by earthquakes in the area of Varaždinska diocese
- review and synthesis of available literature on the earthquake damage consequences and protection measures of the Zagreb and Petrinja earthquakes on the cultural assets of Varaždin, Međimurje and Zagorje counties
- field investigations of individual topographic locations - gathering as much information as possible about the buildings, historical constructions and renovations and topographic characteristics. Preliminary measurements of microtremor were made for the purpose of detection predominant frequencies of the topographic locality.
The goal of historical data research was to gain insight into recurring damage from historical earthquakes on the topographic locality itself or in the immediate vicinity in order to try to learn about the influence of topography on this basis damage from the earthquakes themselves.
