The main objective of this study was to investigate psychological symptoms, which appeared in earthquake-affected people's behavior. Because this study was a preliminary study, so, no hypothesis was tested in this case. Another objective of this study is to collect information about psychological symptoms that may be used in developing a psychometric tool to measure Post-traumatic Stress Disorder (Earthquake-specific). This study was conducted on a small sample of 54 people (Males = 34, Females = 20), selected by incidental sampling method. The age range of the sample varies from 18 to 62 yrs (average age = approximately 35 yrs.). The sample includes students, professionals, employees of educational institution, doctors and older people, too. These people were interviewed by a semi-structured interview schedule, intended to explore their feelings after the earthquake experience. Most of the people included in this study were residents of single-storied to ten-storied buildings. Apart from interview, the findings of this study are also supported by the researcher's observation of people's verbal and non-verbal behavior, as observed during the interview process. The interviews conducted in this study varied from 10 to 30 minutes, depending upon the interviewees' cooperation to the researcher.
