The aim of the project is to strengthen the infrastructure and organizational capacities of the Seismological Survey to increase the quality of collection, processing and application of seismic data necessary for the process of building renovation, planning the development of new buildings and monitoring public infrastructure, as well as strengthening Croatia’s resistance to earthquakes and related risks. Within the project, mobile seismographic equipment will be acquired to define the best locations for seismograph installation. After this initial analysis and definition of suitable locations, seismological stations will be set up on the 95 selected locations. The installation of this equipment will create essential prerequisites for the establishment of a complete network for the collection of seismological data.  

Presently there are 17 seismological stations in the Republic of Croatia (13 stations financed from the budget of the Republic of Croatia, and 4 stations equipped with seismographs that were given to the Seismological Service for use by the City of Zagreb).

The picture shows a map of the currently active state network of seismological stations (red triangles) and the mobile network (blue triangles) of the Seismological Survey.

After the devastating earthquake in Petrinja, the Seismological Survey was equipped with 20 sets of mobile seismological stations for rapid placement in epicentral areas. That was the first investment in the seismological network in the last 20 years. Since they are mobile, portable devices, their primary function is to collect detailed information from earthquake-affected areas in order to monitor the frequency and intensity of aftershocks in an already affected area, and they cannot be considered a permanent solution for establishing a seismological data network. Following all the above, it can be concluded that Croatia has an outdated seismological network that is not in accordance with modern standards, which reduces the possibility of increasing the resistance of the entire territory of Croatia to risks related to seismic activities, increases the risk to people’s lives, the risks of property damage and negative impacts on the economy.
