Sažetak
Earthquake catalogs are foundational data products for earthquake science. For the purposes of this project (SeisRICHerCRO), new uniform earthquake catalogs for investigated areas are prepared. An overview of the new catalogs, and the observed selected statistical and structural characteristics, as well as connection with geological features, are presented. Seismic risk assessment of cultural heritage buildings in Croatia (SeisRICHerCRO) is a research project financed by Croatian Science Foundation. The main objective of the project is the thorough research of the most earthquake-prone area in Croatia, intending to develop a readily transferable methodology and practical procedure for assessing the seismic risk of cultural heritage which include seismic risk assessments on an urban scale. In order to properly estimate the seismic hazard of the selected case study areas, and further seismic risk, the ground objective is a detailed seismicity analysis. Croatia is a very seismically active country, mostly in the northwestern and coastal parts. More than 145.000 earthquakes from the period before Christ till the end of 2020 are contained in the Croatian Earthquake Catalog (CEC). There were more than 100 stronger earthquakes, whose computed or estimated magnitude was more than 5. The majority of the earthquakes on Croatian territory are the result of the strain accumulation caused by the rotation of the Adria microplate towards the Eurasian tectonic plate. Additionally, central Croatia is in a contact zone of three big geological units: The Alps, Dinarides (or The Dinaric Alps), and the Pannonian Basin. Two of the strongest earthquakes, that mainly determined a seismic hazard in Croatia, are the Dubrovnik earthquake (April 6th, 1667.) with a maximum intensity of IX-X °EMS98, and the Zagreb earthquake (November 9th, 1880.) with a maximum intensity of VIII-IX °EMS. Both earthquakes left near cities and villages with great damage. Their historical recordings were used in more detailed and precise reanalysing in this research, and they were included in the newly compiled earthquake catalog. In the presented project, vulnerable buildings of the historical and cultural value of the main focus are Trakošćan Castle in the northwestern part of Croatia, the Cathedral of St. Jacob in Šibenik in the central part of Dalmatia (coastal Croatia), and Dubrovnik old city in the southern part of Dalmatia.
