Hazard Interrelationships and Dynamic Risk Scenarios

This talk presents case examples, critical reviews and dynamic risk scenarios for potential interaction relationships between natural hazards and includes research by myself with multiple colleagues. I first present a wide-ranging review of grey- and peer-review literature used to perform a broad overview, characterization, and visualization of 90 interaction relationships between 21 natural hazards (six hazard groups, geophysical, hydrological, shallow Earth, atmospheric, biophysical, and space hazards). The seminar then considers (i) the role of anthropogenic processes in influencing multi-hazard cascades, (ii) the changing vulnerability/exposure from before, between and after hazard events, resulting in dynamic vulnerability, exposure and risk, and (iii) dynamic risk scenarios, particularly in the context of Istanbul, Nairobi, and Kathmandu.

I will also briefly mention work done on quantifying hazard interrelationships. Our approach allows those undertaking research into single hazards to place their work within the context of other hazards. It also communicates aspects of hazard interactions, facilitating an effective analysis by those working on reducing and managing disaster risk within the policy and practitioner communities. Knowledge of these potential interactions reinforces holistic or multi-hazard approaches to natural hazard assessment.

Bruce Malamud Biography

Since 1 March 2023, I have been the Wilson Chair of Hazard and Risk, and the Director of the Institute of Hazard, Risk and Resilience (IHRR), Durham University where I am also the Wilson Chair of Hazard and Risk. My research focuses on multi-hazard interrelationships along with single hazard research in landslides, earthquakes, floods and wildfires. Research subthemes include anthropogenic processes, invasive species, time-series analyses, mathematical models, visualization, complexity, confronting models with data, and communicating science. I was President for four years (2007−2011) of the Natural Hazards Division of the European Geosciences Union (EGU), Programme Committee Chair for the EGU General Assembly (2010-2011) and Programme Co-Chair of the AOGS–EGU Conference Series on New Dimensions for Natural Hazards in Asia (2018−2022). I am also executive editor of Natural Hazards & Earth System Sciences (NHESS).
