This paper speaks about traumatic experiences and effects of spirituality on resilience of those who went through trauma. In Petrinja, in December 2020., there were devastating earthquakes one of which was felt in whole of Croatia and neighbouring countries. As the result of earthquake, lives were lost, and many people were left without family home. All of that can affect people’s mental health. This thesis is primarily directed towards understanding spirituality as effective and important mechanism of resilience. In the first part of this research 3 subjects were involved, 2 female and 1 male, they answered 8 questions in an interview. Test subjects are staying or living in area affected by earthquake and help people struck by traumatic experience of an earthquake. Results show that spirituality and religion are important mechanism of strengthening resilience. Traumas don't push subjects away from God but bring them closer to God. All three subjects agreed that their resilience is affected by faith, trust in God, sacramental life, prayer, and Holy Scripture. Second part covers 163 test subjects across the Republic of Croatia, 55 male and 108 female, of which 88 persons experienced earthquake in the last year and nine months and 75 persons who have not experienced earthquake in the last year and nine months. Results show that higher spirituality relates to higher resilience. That connection is stronger among persons who have not experienced earthquake. Therefore, there is connection between spirituality and resilience among the people who have and who have not experienced earthquake in the last year and nine months.
