  This paper considers the textual plan (guidelines) proposed by People's
Committee of Ho Chi Minh City (Vietnam) to manage earthquake and tsunami, and
try to represent it in a more formal way, in order to provide means to
simulate, analyse and adapt it. We first present a state of the art about
coordination models for disaster management with a focus on process oriented
approaches. We give an overview of the different dimensions of the textual
tsunami plan of Ho Chi Minh City and then the graphical representation of its
process with BPMN (Business Process Model and Notation). We finally show how to
exploit this process with workflow tools to simulate (YAWL tool) and analyse it
(ProM tool).
