“…However, given that mitigation actions are carried out individually as projects are approved, these do not constitute a hazard-mitigation strategy (Berke et al, 2009). Vertical evacuation in high-density buildings is a possible alternative to deal with this risk exposure, particularly regarding flooding ( Álvarez et al, 2018;León & March, 2016;Qin et al, 2018).…”

Urban form has a significant impact on risk. Spatial planning instruments can optimize urban form in areas exposed to hazards. This work discusses how urban planning instruments, specifically Communal Regulatory Plans (CRP), affect vulnerability to the risk of tsunami inundation in Chilean coastal cities. We analyze urban form and address exposure, susceptibility, and response capacity parameters. Exposure is evaluated by comparing existing and planned densities and to what extent planned risk areas coincide with inundation zones. We analyze existing critical facilities and land uses permitted by the CRP in inundation zones to evaluate susceptibility. We explore response capacity through the street network connectivity and green areas outside the inundation zone and how CRPs influence the structuring of new roads and new green spaces. We found that CRPs do not hold the sufficient capacity to incorporate and manage the tsunami inundation risk adequately. The planning scenario leads to a systematic increase in vulnerability as cities develop in exposed areas. We suggest strengthening CRPs capacities to prevent the construction and reconstruction of areas affected by tsunamis, reinforcing the urban fabric´s potential for evacuation, and strengthening joint work between municipal urban planning and disaster risk management departments, among other recommendations.

“…Factors attributed to a proposed building could be evaluated according to its vulnerability, non-structural parameters and spatial features. Namely, neighborhood density and design are essential to emergency response services during disasters [ 65 , 66 ]. Moreover, urban infrastructures consist of many components, where the road transportation network serves as the most important characteristic related to emergency shelters.…”

Emergency shelters and open spaces play dual roles in providing locations for temporary accommodation and rescue activities during disaster situations. Over time, research has attempted to optimize site selection and design for emergency shelters and open spaces, though they rarely offered lessons to guide actual projects. In this regard, it is paramount to design emergency shelters or open spaces in a forward-looking and dynamic manner, especially when the country faces challenges due to extreme events (e.g. earthquake and floods) and large populations. The aim of this paper is to analyze the issues of this field in China while summarizing instructions for future construction based on the experience and expertise of other countries. Specific suggestions include: (1) combining the designs and plans of emergency shelters/open spaces into the construction of a resilient urban system; (2) embedding routine preparedness into disaster risk reduction approaches; (3) optimizing issues in site-selection using spatiotemporal patterns in refuge demand while designing the shelter system into a hierarchical structure; (4) shifting from a top-down approach to a bottom-up approach, which includes the participation of multiple aspects of shelter construction; and (5) designing and establishing emergency shelters/open spaces to fight against different types of disasters.
