Resilient City and Seismic Risk: A Spatial Multicriteria Approach
•
0 likes•189 views
The document presents a spatial multicriteria approach to identify resilient cities. It involves creating criterion maps to assess factors like accessibility, slope, vulnerability, and seismic hazard. Constraint maps are also used to remove areas with high risks. This is applied to the city of Marsicovetere in Italy as a case study. Different weighting scenarios are defined using pairwise comparison to calculate the most suitable areas for resilient development. The approach aims to help identify resilient cities and inform urban planning and disaster management.

Resilience Facing wth disasters Vulnerability and Resilience Resilient City Spatial Multicriteria Approach Conclusions and directions Urban Resilience is the capacity of individuals, communities, institutions, businesses, and systems within a city to survive, adapt, and grow no matter what kinds of chronic stresses and acute shocks they experience. CHRONIC STRESSES ACUTE SHOCKS Stresses weaken the fabric of a city on a daily or cyclical basis. Examples include: ● high unemployment ● overtaxed or inefficient public ● transportation system ● endemic violence ● chronic food and water shortages. Acute shocks are sudden, sharp events that threaten a city. Examples include: ● earthquakes ● floods ● disease outbreaks ● terrorist attacks Vijay Meena | School of Planning and Architecture Bhopal | vjspab@gmail.com Vijay M eena SchoolofPlanning and Architecture Bhopal vjspab@ gm ail.com
