“…Unlike most studies of community response following an earthquake occurrence and the critical analysis of the emergency situations management generated thereby (Pollino et al, 2012;Wegscheider et al, 2013;Lu and Xu, 2014), the present study demonstrates the importance of GIS analyses in detecting potential congestion and inaccessibility issues in areas where buildings are most likely to collapse and accessibility issues are most likely to arise as a result of an earthquake.…”

“…This assessment of seismic hazard and vulnerability includes quantitative and qualitative data analysis that incorporates physical, environmental, social, and economic factors; potential impacts from existing risk maps; and estimates of the population that would potentially be affected (Mândrescu, 1990;Armaş, 2012;Rufat, 2013;Pollino et al, 2012). The accessibility analysis takes into consideration the specificities of each urban district, especially the urban context (Noto, 2017).…”

“…The Vrancea seismic area is responsible for the highest seismic risk in Romania (Pavel et al, 2014;Ardeleanu et al, 2005). Over the past 76 years, Bucharest has been affected by four earthquakes with a magnitude of between 6.9 and 7.7 on the Richter scale (November 1940, March 1977, August 1986, and May 1990.…”

“…Many areas of high seismic risk are urbanized and densely populated (Pollino et al, 2012;Vatseva et al, 2013). In addition, and coincidentally, many countries experiencing economic transitions are characterized by urban growth that is uncontrolled, and in large and medium-sized urban centres such growth can be especially chaotic (Salvati, 2014).…”

Abstract. Planning for post-disaster accessibility is essential for the provision of emergency and other services to protect life and property in impacted areas. Such planning is particularly important in congested historic districts where narrow streets and at-risk structures are more common and may even prevail. Indeed, a standard method of measuring accessibility, through the use of isochrones, may be particularly inappropriate in these congested historic areas. Bucharest, Romania, is a city with a core of historic buildings and narrow streets. Furthermore, Bucharest ranks second only to Istanbul among large European cities in terms of its seismic risk. This paper provides an accessibility simulation for central Bucharest using mapping and geographic information system (GIS) technologies. It hypothesizes that all buildings in the risk 1 class would collapse in an earthquake of a similar magnitude to those of 1940 and 1977. The authors then simulate accessibility impacts in the historic centre of Bucharest, such as the isolation of certain areas and blockages of some street sections. In this simulation, accessibility will be substantially compromised by anticipated and extensive building collapse. Therefore, policy makers and planners need to fully understand and incorporate the serious implications of this compromised accessibility when planning emergency services and disaster recovery responses.
