description |
<p>Many coastal cities around the world are threatened by tsunamis;
some of these events have caused great impacts in recent times. The loss of
human lives during these events is the main cause of concern of the
authorities, and evacuation planning has been recognized as one of the best
tools for safeguarding the population. In this context, urban design appears
to be critical for the execution of prompt and efficient evacuation processes
to safe areas; however, evacuation assessment has been traditionally carried
out at a large urban scale, mostly taking into consideration urban morphology
and connectivity. In the present work, urban spaces available for tsunami
evacuation are explored in detail by developing a methodology to identify and
classify urban micro-vulnerabilities that may reduce the capacity of the
evacuation routes and hinder evacuees' safety. The method is applied to the
Chilean city of Iquique, affected by an earthquake and subsequent tsunami in
2014.</p> |
