The strong earthquake measuring 6.4 on the Richter scale hit the area of Petrinja town in Croatia on December 29 2020, causing numerous casualties and widespread material damage. The maximum felt intensity was estimated at VIII (Heavily damaging) to IX (Destructive) on the European macroseismic scale, and it is the worst earthquake in Croatia in the last 140 years. Since the initial strong earthquake, the Petrinja area has been hit by numerous aftershocks, magnitudes ranging from 1.2 to 4.8 on the Richter scale, increasing distress of residents and contributing to further damage of houses and buildings. The earthquake and the constant aftershocks caused strong psychological and physiological reactions in children and adults directly affected as well as a large population of people living in the surrounding areas at the time when Croatia was facing a second lockdown during the COVID-19 pandemic.~As part of a public health emergency response, we conducted a rapid assessment among survivors in the most severely affected area by the earthquake. Findings from previous researches among survivors of natural disasters have been mixed in prevalence of mental health problems and treatments outcomes. The aim of this study is to assesses prevalence of symptoms of posttraumatic stress disorder, depression, anxiety, and panic disorder among exposed inhabitants and examine the effect of systemic family therapy on mental health during the first year following the earthquake. Qualitative methodology will be used to augment quantitative findings. The study sample consisted of 350 individuals residing in the earthquake area. Participants were selected from total number of patients requested psychological and psychiatric help during first two months after disaster. A follow up study will be conducted at 6 and 12 months to assess the change in their mental health status.
