Multi-hazard risk assessment using geospatial intelligence

Copy Link

Multi-hazard events pose greater threats to populations and economies compared to single hazard event. A recent study showed that
although multi-hazard events constituted about one-fifth of the total number of natural hazards globally between 1900 and 2023, they
were responsible for 59% of total economic losses. Accurate delineation of multi-hazard risk-prone zones is essential for providing
insights before such hazards occur, enabling the design and implementation of effective risk management and mitigation measures.
Geospatial technologies including earth observations, geographic information system (GIS), global positioning system (GPS), and
spatial statistics are vital in mapping multi-hazard events by integrating various data sources and analytical methods to enhance the
accuracy and efficiency of hazard mapping processes. Furthermore, they play crucial roles in mapping, predicting, monitoring, and
assessing natural hazards, thereby providing valuable insights for disaster preparedness and response. Integrated approaches that
combine hazard mapping with vulnerability assessments can produce comprehensive multi-hazard risk maps, aiding spatial planning
and decision-making processes.

Aim  

This research aims to integrate various data sources related to earth observations and in-situ measurements using geospatial
technologies to assess multi-hazard risks.

Objectives 

  • Develop a spatial inventory of metrices to characterise multi-hazard risk
  • Develop and implement a multidimensional conceptual framework to evaluate vulnerability
  • Identify locations, populations and economies to multi-hazard vulnerability across the Indian Ocean

Significance 

Analysing hazard interactions and interrelations is essential for multi-hazard risk mapping, emphasizing the need to understand how
different hazards can compound and escalate risks. By considering the coupling of various types of hazards, integrated risk maps can
be developed, combining hazard intensity with vulnerability assessments to provide a holistic view of multi-hazard scenarios. However, mapping multi-hazard events and subsequent risks is challenging due to the complex interactions between various hazards in time and space and the presence of different methodologies to quantify hazard interactions. While many attempts have been made to map and assess multi-hazard risks, many ignore the dynamic interactions between hazards. Stability across the Indian Ocean is of paramount importance for Australia. Hence, effective management of multi-hazard could help low-income countries to adapt with climate-driven risks.
Climate warming is expected to result in many adversities (such as sea level rise, heatwaves, cyclones, floods), which have the
potential to affect populations and economies. However, better preparedness can help minimise loss and damages associated with
increased incidence of natural hazards. The intersection of exposure, sensitivity and adaptive capacity has not been achieved to-date
but is necessary to inform public policies and enhance early warning systems.
Geospatial technologies have advanced considerably in the last few decades. They offer sophisticated tools for data management and analysis, risk modelling and evaluation and digital communications. A holistic and synergistic approach combined with science,
technology and innovation can empower local people to address increasing risk to multiple hazards. The project can use Google Earth Engine (GEE) to work with multi-dimensional data and analytics. The proposed work is directly aligned with the Spatial Science
discipline.
