Contemporary mine exploitation requires information about the deposit itself and the impact of mining activities on the surrounding surface areas. In the past, this task was performed using classical seismic and geodetic measurements. Nowadays, the use of new technologies enables the determination of the necessary parameters in global coordinate systems. For this purpose, the relevant services create systems that integrate various methods of determining interesting quantities, e.g., seismometers / GNSS / PSInSAR. These systems allow detecting both terrain deformations and seismic events that occur as a result of exploitation. Additionally, they enable determining the quantity parameters that characterise and influence these events. However, such systems are expensive and cannot be set up for all existing mines. Therefore, other solutions are being sought that will also allow for similar research. In this article, the authors examined the possibilities of using the existing GNSS infrastructure to detect seismic events. For this purpose, an algorithm of automatic discontinuity detection in time series “Switching Edge Detector” was used. The reference data were the results of GNSS measurements from the integrated system (seismic / GNSS / PSInSAR) installed on the LGCB (Legnica-Głogów Copper Belt) area. The GNSS data from 2020 was examined, for which the integrated system registered seven seismic events. The switching Edge Detector algorithm proved to be an efficient tool in seismic event detection.

Wine is a crucial part of the cultural history of the territory within the current borders of Bulgaria from the earliest times until now. It plays an important role in the life of Bulgarians and is a multiethnic heritage of this land. Bulgarian toponyms only archive a lexicon associated with wine in a small degree, with more toponyms found regarding vines and vineyards which were characteristic elements of the native landscape. The Bulgarian enonyms constitute a “multilingual patchwork”, where the locality (present, but not dominant) is mixed with globality. Locality is mainly reflected in the detoponymic and deanthroponymic names referring to the Bulgarian heritage and also the Thracian, Greek and Roman legacy of those lands. Globality is revealed in the linguistic “hybridity” manifested by the free use of foreign models, naming vocabulary and intertextuality appealing to a global experience. This part of Bulgarian enonymy derives mainly from the English and French language, as well as Spanish, Italian, Greek and Latin.
