According to the observations at the seismic stations of the Carpathian region of Ukraine in 2024, the main parameters of 55 earthquakes in the range of energy classes KR=5.5÷12.4 were obtained. The parameters of seismometric equipment at active seismic stations are given. A catalog of earthquakes, their distribution by regions and energy classes, a map of epicenters, graphs of seismic energy release, and the number of earthquakes in the region by month are presented. A brief description of the seismicity of certain seismically active areas of the Carpathian region is given. The total energy allocated to the region was ΣЕ=4.09·1012 J, which is an order of magnitude lower than last year’s ΣЕ=9.06·1013 J. This year, increased seismic activity was observed in three seismically active areas. Thus, 16 earthquakes of energy class KR=5.5÷9.8 were recorded in the North-Western region. Their total seismic energy was ΣЕ=1.53·1010 J. In this area, the strongest earthquake occurred on February 22 at 12h54m on the territory of Slovakia, near the town of Humenné, with KR=9.8 at a depth of h=12.9 km and epicenter intensity of I0=3 points. In the Vrancea region, as in the previous year, 19 events with magnitudes of 8.4—12.4 were registered, with the total seismic energy of ΣE=2.97·1012 J, which is higher than last year’s ΣE=6.41·1011 J. This year, there has been an increase in seismic activity in Bukovina compared to 2023. 10 earthquakes of an energy class of KR=5.7÷8.9 and a total seismic energy of ΣE=1.72·109 J were registered here. The earthquake foci were located in the crust at depths of h=1.0÷15.0 km. In the Southern Carpathians, there was a decrease in activity compared to 2023. In total, 2 earthquakes with KR=8.7 and 10.3 were registered here at depths of 5 and 7.7 km with a total seismic energy of ΣE=2.05·1010 J. A decrease in activity is also observed in the Crișan region. Only one event with KR=9.2 was registered here. This year, the Banat region has become more active. During the year, 3 earthquakes of KR=9.4÷12.0 were registered here, with the total seismic energy of ΣE=1.02·1012 J. In the Bacău region in 2024, only two earthquakes with KR=9.5 and 10.4 were registered, and none were registered in the Transylvania region. Two more earthquakes were registered in the region, but outside the seismic areas. The regional Carpathian hodograph was used to determine the main parameters of earthquakes in Transcarpathia, and the Jeffreys-Bullen hodograph was used for earthquakes in the Vrancea zone and other six districts.
