Exposure, Vulnerability & Impacts

Natural risk depends upon hazards interacting with exposed assets and populations through vulnerabilities to these forces. Effective risk modelling depends upon accurate inventories of exposed portfolios capturing the characteristics driving vulnerability to relevant hazards. The Network's research programme enhances available exposure data and refines vulnerability functions of assets to inform hazard modelling programmes.

Exposure Data.

Information on the built environment is augmented from a variety of records and surveys, new ground based surveying techniques, remote sensing and satellite systems combined with consistent, high resolution geocoding provide new opportunities for enriched exposure information from urban to rural locations.

Post Event Response and Forensic Analysis.

WRN members participate in post event disaster surveys as part of international teams to assess damage and understand the performance of structures and civil response agencies. WRN members are pioneering a new style of forensic event analysis to provide a consistent and structured approach to documenting loss events and developing a body of evidence to inform risk assessment, disaster risk reduction and policy making.

About WRN

As economic, social and environmental uncertainties increase, institutions and populations seek greater resilience to support sustainable growth. Science and insurance lay at the heart of understanding, managing and sharing these risks, building more secure futures at local and global scales.

The Willis Research Network (WRN) operates across the full spectrum of risk from natural catastrophe, to legal liability, financial and security issues linked across driving themes: Resilience, Security & Sustainable Growth; Managing Extremes; Insurance & Risk Management and Mastering the Modelled World.

All Members and activities are united by a common aim: improving resilience by integrating first class science into operational and financial decision-making across public and private institutions.
