On Tuesday, 17 January 2023, the first meeting of Component 1 of the CRONOS project was held. Attending were Josip Stipčević, Iva Dasović, Dinko Šindija, Branimir Turudić, Helena Latečki, Lucija Golub, Nina Matsuno, Marijan Herak, Marija Mustać Brčić, Bojan Matoš, Darko Matešić, and via Teams, Tena Belinić Topić and Ivica Pavičić joined. The purpose of the meeting was to present everything that has been done so far and to outline plans for further work.
The first presentation was given by Josip Stipčević, who provided an overview of the work done to date and future activities. The objectives of the Component 1 of the CRONOS project were presented: to set up a network of seismographs in Dalmatia, to monitor seismicity and map active faults, to study tectonic and geodynamic processes using seismological and geological data, and to create a scenario of earthquake shaking for one of the seismically active areas. Three project phases were presented, with the first phase already completed – 12 seismic stations were installed in Dalmatia (9H network). The next phase involves the installation of another 13 instruments in a profile by the end of 2023, which would achieve the most important goal of the project – setting up a local network of seismographs in Dalmatia. Seismicity is continuously monitored throughout all three phases, which will be linked to active structures in later phases. The third phase of the project consists of data processing and interpretation, obtaining a new (preliminary) structural model of the crust with mapped active structures and realistic numerical simulation of earthquake shaking in Makarska. Several field works are required for mapping active faults. Lastly, the status of public procurement of instruments was presented.
Dinko Šindija presented the CRONOS seismic network of 12 seismographs. He described the installation process and problems that occurred at some stations. Furthermore, he introduced the Seiscomp3 seismological software that is used for storage, processing, distribution, and interactive data analysis. He explained how to data is stored and how to access the server. Moreover, he described how to use newly acquired workstation for data analysis and computationally demanding numerical modelling.
Helena Latečki presented the installed 9H network of seismographs and the seismicity of the monitored area. In the third phase, the plan is to numerically simulate seismic shaking of the Makarska area based on the strong earthquakes that occurred in January 1962.
Bojan Matoš described the goal and study area of geological research. So far, sedimentary-stratigraphic and structural data have been collected, which will be used to create a 3D seismic model of the crust. In the field investigations in 2022, 152 observation points were explored, and more field work is planned.
Finally, Iva Dasović provided an overview of the project’s website and talked about social media and how to increase public interest and reach of posts. Accordingly, there was discussion about outreach in schools near the locations of seismic stations and at various events and workshops held for the purpose of science popularization.
