Iva Lončar, a collaborator on the CRONOS project within Component 2, participated in the 2nd Croatian Conference on Earthquake Engineering (2CroCEE), organized by the Faculty of Civil Engineering at the University of Zagreb, on March 23, 2023.
As part of the PhD session, Iva gave a three-minute presentation titled “CRONOS project: Main features of seismicity analysis for the central and southern Croatian coastal area”. In the presentation, she briefly introduced the project itself and the preliminary results of seismicity analysis for the CRONOS project’s research area.
In the research results, which she conducted with Assoc. Prof. Snježana Markušić, PhD, and Ines Ivančić, MSc, she briefly presented an overview of the historical seismicity of the central and southern Croatian coastal area. The observed area is also one of the most seismically active areas in Croatia. A better understanding of the seismicity of a given area is the first step towards better assessing seismic hazard and, therefore, better preparedness for future strong earthquakes, which is the aim of the CRONOS project. The earthquake catalog of the research area contains more than 44,000 earthquakes, estimated or recorded, with a magnitude of up to 6.7, with more than 400 of them being magnitudes greater than 4. Although most of these strong and destructive earthquakes were recorded before instrumental recording began, the last century was also seismically turbulent. There have been a series of strong earthquakes that have caused significant damage and human casualties, such as the M6.2 earthquake that occurred near Imotski in 1942 and the M6.1 earthquake near Makarska in 1962. Additionally, a completeness analysis was conducted on the mentioned CRONOS catalog for several different years.
We would like to thank Croatian Seismological Survey for providing us with earthquake catalogue data.
