On the April 22, 2022. at 21:07:49 UTC, the strong earthquake with Mw 5.7 magnitude occurred on the south of Bosnia and Herzegovina. The epicenter is located between Stolac and Berkovici municipalities, at a depth of 19 km (EMSC). That earthquake was felt all throughout BIH but also in the wider region. It caused the collapse of chimneys, damage on buildings and induced landslides in parts of the slopes, so that the residents of eastern Herzegovina (Stolac, Capljina Ljubuski, Berkovici, Ljubinje, Bileca, Trebinje but also Mostar) spent the night on the streets. According to the research carried out on the spot and the information obtained, cases of rock falls are not a rare case in these areas. The trigger of rockfall is different, from heavy rains, strong winds, temperature fluctuations and earthquakes, as was the case here. Geologically speaking, the terrain is made of crumbling, chalky dolomite and limestone. Since they are located in an outcrop, with a strong slope angle, over 65 degrees, and the objects are located immediately below the slope, then this explains the "shelling" of objects with stone projectiles during any of the above-mentioned hydrological-geological changes. As we are dealing with a significant number of residential buildings, it is necessary to record the terrain in detail as soon as possible and determine which is the most efficient and economically profitable way of stabilizing the slope above the buildings, i.e., the installation of walls and rock catchers at the foot of the slope.
