The practical part of this final paper entitled "Unexpected Vibration" is divided into two parts, including sound. The first part is five graphic prints showing the mountains named by coordinates and sorted by earthquake risk (seismic activity), made by a combined technique of intaglio printing, reserve and screen printing. Dinara: 44 ° 03’20.8 ”N 16 ° 21’46.0” E Velebit: 44 ° 40’00.3 ”N 14 ° 56’11.8” E Risnjak: 45 ° 29’38.0 ”N 14 ° 40’56.4” E Medvednica: 45 ° 56’08.2 ”N 16 ° 03’36.5” E Papuk: 45 ° 31’59.1 ”N 17 ° 37’34.0” E The second part is a stop animation (drawing in charcoal) showing the transition from hilly areas to the flat Slavonian region in the presence of occasional earthquakes. The sound of the piano follows the dynamics of the drawings in the animation and mimics the earthquake in duration. Specifically, a sound to alert and encourage visitors to think about the topic. The intention of the work was to reawaken respect for nature, both for the people and for nature itself, for its importance and the gratitude it owed. Natural disasters have always caused a change or transition from one period to another, as they do in us now.
