The Application of Urban System Analysis To The Seismic Risk Assessment of Barcelona
Abstract
The Urban System Analysis methodology developed by an international team directed by the BRGM (France) within the GEMITIS research program (1996-1999) consists of a global and integrated risk reduction strategy in order to improve the risk assessment effectiveness through the use of a geographical information system (GIS). A typical seismic risk analysis evaluates only the direct impacts of the earthquake, but gives few information about how to improve preventive effectiveness because it does not provide any data about the indirect consequences of an earthquake. This new methodology proposes to complete the scenario generation process by focusing physical vulnerability assessment on the essential elements for urban functioning. Besides it gives rational bases for the definition of appropriate risk management and preventive action plans. This study presents a first stage of the application of the Urban System Analysis method to the city of Barcelona. The elements at risk in the city like the residential, commercial, administrative, and industrials areas are identified and analyzed to define the weak points within its urban system. Then the most critical elements within the city's urban system will be identified to establish priorities for risk managements plans in the city.
