seismic risk in urban areas

The research (for the Umbria Region) belongs to urban scale seismic prevention studies. It has three main objectives: experimenting the ELC (Emergency limit condition) and Strategic urban framework (SUM in italian) in four cities in Umbria; defining general criteria to evaluate the ELC and the seismic emergency management system; focusing on planning consequences of ELC and SUM at a local planning scale

The activities involve analyses at different scales on four settlements (Acquasparta, Bastia Umbra, Bevagna, Marsciano) from territorial and urban studies up to buildig scale surveys

Main results are guidelines and references to promote the reduction of seismic risk through master plans

a renewed territory. a planning look over the post-earthquake reconstruction in umbria 1997 – 2007

The book is based on a research for Umbria Region dedicated to planning aspects of post-seismic reconstruction after 1997 earthquake.

The book is divided into four parts: first three parts deals with the territorial conditions before earthquake, the post-emergency acts, the regional and urban situation ten years after the seismic event. The fourth part expose some reflections about new settlements and historical towns, whose structure has been changed after ten years of reconstruction.

The conclusions suggest new perspectives on regional development and seismic hazard prevention at an urban scale

The Umbria 1997 earthquake involved different consequences at many levels. Destruction of cultural heritage and historical buildings, loss of urban funcionality and demographic decrease specially in small towns demonstrated that a seismic event produces a complex damage wich is more relevant than the sum of different damages on building environment.

Post-seismic interventions has been displayed in different sectors. Their influence on many different places is easy to demonstrate. Furthermore they had also a general effect; not only on physical configuration of every single urban context but also on the appearance of the whole region and on its social representation. In a word the reconstruction process produced effects also on the regional landscape.

Therefore reading different “earthquake landscapes” of Umbria requires to take a look on different transformations due to reconstruction, from different points of view.

This book collects many images of these modifications as a first step for a possible discussion on the reconstruction process
