| Summary: | This article aims to study the transformation of seismic risk in Istanbul’s urban areas, focusing specifically on developments in the building sector. Since the 1999 earthquakes in the Marmara region, many laws, codes and standards governing building materials have been established in Turkey as a response to the threat of earthquake-induced building collapse. Describing successive assemblages of actors involved in using building tools to negotiate seismic risk management, we examine how risk and the urban environment are evolving conjointly. The first part of the analysis examines the construction sector’s regulatory framework since 1999, which has shifted responsibility for seismic risk from the state to construction industry actors; that is, service providers, construction auditors, material producers and civil engineers. It then goes on to explain the choices made by players in the building industry who favor the demolition and reconstruction of buildings rather than their rehabilitation. This process, however, generates economic and financial risks correlated with that of building collapse, the interactions of which highlight controversies surrounding the circumvention of construction standards, sometimes leading to increased individual vulnerability. We conclude that earthquake hazards are gradually being diluted into a more complex assemblage of risks, involving the interdependence of multiple factors that play a role in the fragility of the built environment and the actors concerned. |
