As a result of the flooding of the former Siersza mine in Poland, as well as in connection with the phenomena occurring – periods of prolonged drought and subsequent intensive precipitation – dangerous events on the surface related to the loss of stability of the ground are recorded with increasing frequency. In the period 2021-2022, more than 12 such events occurred, the most ‘spectacular’ of which are: a sinkhole in the mining area of the former Siersza mine – in the area of the allotment gardens in Trzebinia – this sinkhole occurred in the area of the allotment gardens on 24.11.2021, a sinkhole in the area between Jana Pawła II Street in Trzebinia and the allotment gardens, which occurred in an open area on 25.07.2022, and a sinkhole in the area of the cemetery on the Gaj district in Trzebinia on 20.09.2022.
