On Tuesday, January 3rd, 2023, a working meeting of the CRONOS project Component 2 collaborators was held. The meeting was held for the purpose of reporting and analyzing the tasks completed in the first year of the project and developing a plan for future tasks.
The final hiring process for a collaboration position, previously held by former collaborator Jakov Stanislav Uglešić, is underway. Field research was agreed upon to be conducted from January 16th to 30th. Two research groups were planned to go to the Dalmatia area for drill site location scouting for borehole accelerographs (Davor Stanko and Tvrtko Korbar) and HVSR research (Mario Gazdek, Lada Dvornik, and Iva Lončar). Professional development of collaborators Lada Dvornik and Iva Lončar in using QGIS software, necessary for final project result visualization, was also agreed upon.
At the meeting, the results of the current research were presented and potential issues were identified and further activity dynamics were defined. Iva Lončar’s research was presented, which analyzed the seismicity of the CRONOS project study area, such as determining magnitude and completeness year of the earthquake catalog, and presenting the weighted earthquake distribution. The need for potential expansion of the analyzed region and the possibility of reanalyzing some historical earthquakes were pointed out. Davor Stanko presented research aimed at finding instrument placement locations, listing final locations of various instrument types and describing their geology and additional necessary equipment for each of them. A discussion among the meeting participants on potential remaining locations was initiated. The results of former collaborator Jakov Stanislav Uglešić’s research were also presented, which described the method used to define representative attenuation relationships for the subject area and presented the results for the relationships tested by that method. Finally, Lada Dvornik’s results on Openquake opensource software for obtaining hazard maps were presented. The necessary data was defined and the construction of necessary input files was agreed upon.
To conclude the meeting, the dynamics of further research, procurement organization and implementation, and potential data transfer and instrument power supply organization (related to the planned instrument network) were defined.
