Geodynamic framework and regional structure as factors affecting the Earthquake Planning of Zakinthos Municipality (Greece)

摘要

The Zakinthos town (Zakinthos island, Western Greece) has suffered in the past repeated disasters by earthquakes with most outstanding episode the 1953 earthquake. The high seismic risk is attributed to the particular geodynamic setting of the broad region. In this framework it is considered worthwhile and essential to work out a plan of emergency action in order to minimise the consequences. The organisation of the plan was based on a number of factors, which constitute the problem, the main of which are the geodynamic framework and the given regional and urban stucture. Especially, based on the arising evidence it is found out that the broad area is within a negative geodynamic framework which is characterised by the presence of non favorable geological formations, landslides, settlement, active faults, liquefaction, etc. Furthermore the regional and urban structure of the city was studied. Based on these facts an emergency action plan is proposed in case of an earthquake which includes recommendations for escape ways, assemblage spaces, camps, space for accommodation of public services, areas for rendering first aid service, etc.
