Abstract
AbstractThe Carpathian Mountainsarc is the most seismically active area in Central Europe. Analysis of the seismicity of entire Carpathian arc requires data from each of the particular catalogues which have to be properly and uniformly entered, standardized and merged. For our study we first had to prepare a database of seismic events (ML≥ 1.6) compiled from the data of earthquakes taken from individual national seismic networks as well as data from international seismic centers. However, a careful review of these catalogues has uncovered significant inconsistencies, particularly discrepancies in the description of the location, magnitude and completeness of seismic events. To address these inconsistencies, a newly created compound earthquake catalogue was compiled from the aforementioned seismic catalogues and included events that occurred in the Carpathian Mountains arc area between 1976 and 2017. This work is intended to point out some of the problems associated with collecting data from various seismic catalogues as well as the need for their very careful verification, in order to create a uniform set of seismic data across a large area spanning numerous countries. The results suggest that compiling a uniform and dependable earthquake catalogue is crucial for reliable seismic studies.

Earthquake catalogues represent the most important data sets for studying different aspects of seismicity within a. Because of the data available in the seismic catalogue from the USCB we needed to compile the database containing events occurred between 1976-2017 which strength was expressed by local magnitude (ML), like in the USCB catalogue. Analyses of the entire Carpathian area would require data from all available catalogues of the individual national seismic networks and international seismological centers, all of which would need to be completed, standardized, and merged in order to obtain a homogeneous earthquake data. This article is intended to show the importance of proper data collecting from various seismic networks, as well as the need for very careful verification of partial seismic catalogues, in order to create a single set of data regarding the seismic phenomena across a large area
