Abstract: On the April 22, 2022. at 11:07 p.m., an earthquake occurred with the epicentre in the area of Berkovici Municipality, at a depth of 5 km, magnitude M 5.7 according to Richter. The same was felt throughout BIH, but also in the wider region. It caused the collapse of chimneys, damage to buildings and landslides in parts of the slopes, so that the residents of eastern Herzegovina (Stolac, Capljina Ljubuski, Berkovici, but also Mostar) spent the night on the streets. The municipality of Stolac suffered significantly, with one victim and several injured due to rockfall, which were triggered during the earthquake. An earthquake of this magnitude is always followed by a relaxation of the ground, so that during a period of a few months afterwards Stolac and its surroundings were shaken by dozens of smaller earthquakes, which caused additional anxiety among the residents of Stolac.
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 causes of rockfall are 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 large slope, 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, which would in a certain way secure the buildings from similar engineering geological processes in the future and protect the lives of the inhabitants of this area.
