The purpose <\/strong>of the article is to investigate instances and processes of dangerous soil subsidence by studying temporal variations in micro seismic fluctuations in the area of the National Reserve \u201cSophia\u201d. The research is based on the registered and analyzed seismic events of different genesis, and the collected records of micro seismic phenomena caused by a soil faults of the Reserve. The research is aimed at developing methods to conduct works, measure tem\u00adporal micro seismic variations, and analyze the experimental records.
\nDesign\/methodology\/approach. <\/strong>The study was carried out by recording temporal variations in micro seismic fluctua\u00adtions. To register micro seismicity, we used a certified seismometer GURALP CMG-40T.
\nFindings. <\/strong>Based on the readings of the seismometer, we have built maps of maximum, medium, and minimum values of the amplitude and deviation in temporal variations of micro seismic vibrations for E, N, and Z channels. The maps of micro seismic temporal variations of vibrations have shown an anomaly in the area of soil subsidence.
\nPractical value\/implications. <\/strong>The subsidence could be caused by the destruction of the walls of the Reserve under\u00adground catacombs, the change in the hydrological regime in the area due to frequent watering of the lawns, and the construction works under way around the Reserve. In interpreting the information obtained while measuring temporal variations in micro seismicity, five anomalous zones were detected. Four of them are correlated with the known zones of soil subsidence. On the picket 13, a fresh anomaly has occurred, which is likely to be the area of future instances of soil subsidence.<\/p>\n
