The article describes seismic observations in the Carpathian region in 2016–2017, which were carried out, as before, by two organizations from two states: in Ukraine – the seismicity department of the Carpathian region of the Institute of Geophysics of the NAS of Ukraine, in Moldova – the seismology laboratory of the Institute of Geology and Seismology of the Academy of Sciences of Moldova. In Ukraine, 20 stationary digital stations and 1 temporary in the area of Stebnik with a processing center in Lviv, in Moldova – six stations with a center in Chisinau. Different programs, local hodographs and magnitudes were used. The consolidated catalog of earthquakes was created in Lviv. A maps of epicenters and a table of the distribution of earthquakes of different classes by region are given. The total number of earthquakes in 2016–2017 was NΣ=140 in the range KR =4.0–14.4 with depths h=1–160 km and the total seismic energy ΣE=2.92·1014 J. The maximum earthquake with KR=14.4, MSH=5.7 and hрР=95 km was registered on September 23, 2016 located in the Vrancea zone. The earthquake was felt by the population in Romania and Moldova. In the cities of Chisinau and Cahul, the earthquake was felt with intensity I=3–4 points. In the Precarpathian and Transcarpathian regions, all earthquakes are weaker. The strongest event in Transcarpathia was a tangible earthquake, which occurred north of the village of Uglya, Tyachevo district, on June 6, 2017 with KR=9.8, of h=5 km. The earthquake was felt by the population of 20 settlements with an intensity ranging from 2 to 4–5 points. The most powerful event in Precarpathian in 2016–2017 there was a tangible earthquake that occurred in the Drohobych district of the Lvov region on September 29, 2017 with KR=9.8 at a depth of 1.9 ± 0.4 km. Perhaps it was a tectonic earthquake that triggered a collapse in the mine, or vice versa – the collapse of the rocks was recorded as a seismic event. The strongest event in Bukovina was an earthquake that occurred on July 12, 2016 at 18h21m with an energy class of KR=9.9 and magnitude МSH=3.0 in the area of the village of Kurazhin, Khmelnitsky region and was felt by the population with an intensity of 3–4 points. In general, in the seismically active zone of Vrancea and Bukovina in 2016–2017 there was an increase in the level of seismicity compared to those in 2012–2015, and in areas № 1, 3 and 8 there was a slight decrease in the level of seismicity.
The article describes seismic observations in the Carpathian region in 2015, which were carried out, as before, by two organizations from two states: in Ukraine – the Seismicity department of the Carpathian region of the Institute of Geophysics of the NAS of Ukraine, in Moldova – the Seismology laboratory of the Institute of Geology and Seismology of the Academy of Sciences of Moldova. 20 stationary digital stations with a processing center in L'viv and six stations with a center in Chisinau operated in Ukraine and Moldova respectively. Different programs, local hodographs and magnitudes were used. The consolidated catalogue of earthquakes was created in L'viv. The total number of earthquakes in 2015 was NΣ=164 in the ranges: KR=4.7–12.2, h=1–160 km. The total seismic energy ΣE=5.381012 J. 23 earthquakes with depths h=50–160 km were located in the Vrancea zone. The maximum earthquake with KR=12.2 was registered on January 24 in the Vrancha mountains with hрР=89 km. In the Precarpathian region, nine events with energy classes KR=4.7–8.9 were registered, the total seismic energy of which is ΣЕ=1.25109 J. Increased seismic activity was observed in Transcarpathia. A series of tangible earthquakes with aftershocks was recorded in the Tyachiv area. Their total number was NΣ=77. The strongest tangible earthquake occurred in the area of Okrugla village on July 19 with KR=11.1. The earthquake source is located in the Earth's crust at a depth of h=7.7 km. The earthquake was felt by the population in the epicentral area with an intensity of I=6. In addition, this earthquake, like 5 others, was felt in the territory of northern Romania. In general, a decrease in the seismicity level in the Carpathians in 2015 was observed compared to that in 2013 and 2014.
The article describes seismic observations in the Carpathian region in 2014, which were carried out, as before, by two organizations from two states: in Ukraine – the Seismicity Department of the Carpathian region of the Institute of Geophysics of the National Academy of Sciences of Ukraine, in Moldova – the Seismology Laboratory of the Institute of Geology and Seismology of the Academy of Sciences of Moldova. In Ukraine, 20 stationary digital stations and 3 temporary ones worked in the Dniester energy complex with a processing center in Lviv, in Moldova - six stations with a center in Chisinau. Different programs, local hodo-graphs and magnitudes were used. The consolidated catalog of earthquakes was created in Lviv. A map of epi-centers and a table of the distribution of earthquakes of different classes by region are given. The total number of earthquakes in 2014 was NΣ=81 in the range KP =5.2–14.3 with the interval of hypocenter depths h=1–154 km and the total seismic energy ΣE=2.11·1014 J. Of these, 18 earthquakes with depths h=77–154 km located in the Vrancea zone. The maximum earthquake with KP=14.3 was registered on November 22 in the Precarpathian Trough with hрР=37 km. In the Vrancha mountains the maximum earthquake occurred on March 29 with the KP=12.5 and hрР=136 km. In the Precarpathian and Transcarpathian regions, all earthquakes were weaker. The most powerful event in Transcarpathia was a perceptible earthquake that occurred near the Trostnyk seismic station on November 15 with KP=8.9. The earthquake source is located in the Earth's crust at a depth of h=10 km. The earthquake was felt by the population of the Dyakovo, Trostnyk, Fanchykovo villages with the intensity of 5 and 4–5. In general, in all the seismically active zones of the Carpathians in 2014, there was a slight increase in the level of seismicity compared to that in 2013.
