Stop going around in circles: towards a reconceptualisation of disaster risk management phases
Year: 2021
Purpose The way that disasters are managed, or indeed mis-managed, is often represented diagrammatically as a “disaster cycle”. The cyclical aspects of the disaster (risk) management concept, comprised of numerous operational phases, have, in recent years, been criticised for conceptualising and representing disasters in an overly simplistic way that typically starts with a disaster “event” – and subsequently leads onto yet another disaster. Such cyclical thinking has been proven to not be very useful for the complexities associated with understanding disasters and their risks. This paper…

Evaluating rural Pacific Northwest towns for wildfire evacuation vulnerability
Year: 2021
Wildfire is an annual threat for many rural communities in the Pacific Northwest region of the United States. In some severe events, evacuation is one potential course of action to gain safety from an advancing wildfire. Since most evacuations occur in a personal vehicle along the surrounding road network, the quality of this network is a critical component of a community's vulnerability to wildfire. In this paper, we leverage a high-resolution spatial dataset of wildfire burn probability and mean fireline intensity to conduct a regional-scale screening of wildfire evacuation vulnerability…

Defining extreme wildland fires using geospatial and ancillary metrics
Year: 2014
There is a growing professional and public perception that ‘extreme’ wildland fires are becoming more common due to changing climatic conditions. This concern is heightened in the wildland–urban interface where social and ecological effects converge. ‘Mega-fires’, ‘conflagrations’, ‘extreme’ and ‘catastrophic’ are descriptors interchangeably used increasingly to describe fires in recent decades in the US and globally. It is necessary to have consistent, meaningful and quantitative metrics to define these perceived ‘extreme’ fires, given studies predict an increased frequency of large and…
