On the night of September 17, 2026, a new seismic event was recorded on the territory of Ukraine. According to the Main Center for Special Monitoring (MCSC), which monitors geophysical phenomena across the country and the globe, the underground tremors occurred at 01:31:45 Kyiv time. This is already the fourth earthquake registered in Ukraine since the beginning of September 2026, making the current month one of the most seismically active in recent times.
Parameters and location of the event
According to the materials published by the MCSC, the epicenter of the tremors fell within Sambir District of Lviv Oblast. On the source's event map, the underground tremors were recorded near the Carpathian village of Nyzhnia Yablunka, and at a wider scale it can be seen that the incident occurred relatively close to the state border with Poland. The center's experts, having assessed the energy parameters, classified the event as an imperceptible earthquake — meaning such tremors are, as a rule, not felt by people and are unable to cause damage to infrastructure.
Fourth this month: the seismic background of September
As emphasized by the MCSC, four earthquakes have already been registered in Ukraine since the beginning of September 2026. The sequential recording of events in different regions indicates that the seismic background in the country remains at an elevated level, and specialists continue to carry out continuous monitoring. This is precisely why each new event is recorded and published in the public domain, so that citizens can stay informed about what is happening.
The center's appeal to citizens
MCSC specialists appealed to all citizens with a request to share information about their own sensations. "If you felt the earthquake, please leave a message about your sensations via the link on the institution's official website," the center urged. It is emphasized that such data will help refine the energy parameters of the earthquake and increase the accuracy of subsequent scientific assessments. Thus, the contribution of each observer becomes part of the overall monitoring system.
Contradictory data
When comparing publications from different outlets, a discrepancy was found in the description of the event's location. The main text, citing the MCSC and its maps, points to Sambir District of Lviv Oblast and the village of Nyzhnia Yablunka. At the same time, a number of sources describe the epicenter as being "near Hoverla," which geographically already falls within the territory of Ivano-Frankivsk Oblast. The misreading is likely due to the general use of the term "Carpathians" and imprecise wording in individual materials. The official and most detailed version, based on the MCSC's maps, remains the localization in Sambir District of Lviv Oblast.
Overall, the earthquake recorded on September 17, 2026, had no consequences and was classified as imperceptible. Nevertheless, its registration continues the series of four events in September, confirming the need to maintain vigilance and to keep citizens promptly informed by the relevant services.
