Stuttering is a speech disorder which symptoms are visible on a verbal, physical, emotional, physiological and social level. The speech of stutterers is accompanied by the appearance of non-stuttering inaccuracies and stuttering inaccuracies that manifest itself in the form of blockages, tense pauses, repetition and prolongation of words or parts of words. The etiology can be psychological or biological, and stuttering can occur as a developmental or acquired disorder. In accordance with the occurrence of devastating earthquakes in 2020 and 2021, efforts are being made to determine whether earthquakes caused emotional damage in addition to material damage. The lives of most Croatian citizens are accompanied by stress, nervousness and fear due to the occurrence of earthquakes, and efforts are being made to investigate how the earthquake affected stuttering and the emotional state of people who stutter. The first study based on the impact of earthquakes on stuttering seeks to examine the newly formed emotional state of people who stutter and changes in the intensity or manner of stuttering. The aim of this thesis is to examine the impact of earthquakes on stuttering, and to examine the characteristics of stuttering before and after earthquakes. For the purposes of the research, an online questionnaire was created via the Google Form platform entitled "The Impact of Earthquakes on Stuttering". The form intended for adults and adolescents contains 16 items, while the form intended for children contains 15 items. It is inevitable that the earthquake affected, to some extent, not only the people who stutter but all of us. According to the results of the answers of 18 respondents, we can conclude that although the majority stated that they felt an increase in the intensity of stuttering due to earthquake, this phenomenon did not significantly affect the emotional state of the person or encourage stutterers to seek speech therapy intervention. However, given that the pandemic caused by the COVID-19 virus also took place at the same time as the earthquake, we cannot exclude the effects that earthquakes had exclusively from other negative factors that also affected the stuttering person.
