Socio-demographic determinants of earthquake risk perception: the case of the Corinthiakos Gulf, in Greece.

Risk perception has been widely recognized as an essential factor in shaping attitudes and behaviors of individuals and communities proactively, during and after the experience of extreme catastrophic events. Its importance derives out mostly due to its intrinsic relationship with socioeconomic parameters and capacity building of communities affected by such events. The aim of this paper was to elaborate on the demographic and socioeconomic determinants of earthquake risk perception of populations living in an extremely earthquake-prone environment. For this purpose, a population sample of municipalities in the Corinthiakos Gulf in Central West Greece was examined. The sample (230 men and 276 women) was randomly selected from three coastal municipalities of the Gulf: Aigialeia, Nafpaktia and Corinthos. Multi-adjusted linear regression analysis was performed to reveal the determinants of the participants' perceptions regarding earthquake risk. Findings revealed that mean earthquake risk perception score was moderate in both men and women and notably lower for the participants living in the municipality of Nafpaktia, as compared to the participants of the other two study areas. Earthquake risk perception varied significantly according to age, sex, income and building construction period (of assets resided or used by the participants). Younger strata, especially young men, and households of lower-income status tend to correlate to lower earthquake risk perception. Moreover, individuals living in newly constructed buildings presented lower earthquake risk perception levels. Also, increased individuals' earthquake safety information provided by state agencies and local civil protection authorities was associated with increased risk perception. Issues like education, household structure, building earthquake insurance, savings and trust in civil protection authorities were not associated with risk perception. From a policy design point of view, such findings provide noteworthy insights for local communities and civil protection authorities allowing to identify vulnerable population groups and to provide noteworthy insights to design targeted measures and policies in the making of a safe and resilient environment.
