Tsunami early warning system (EWS) and its integration within the chain of seismic safety

Abstract

Purpose

This paper aims to provide a broad overview of the South Asian tsunami in relation to the development of the early warning system (EWS) as well as its integration within the seismic safety chain.

Design/methodology/approach

The paper focuses on social and administrative aspects that require detailed attention as key elements within the overall system. The observations grow from experience gained by Ian Davis from working on the UK IDNDR Flagship project Warnings and Forecasts from 1996‐9 and from participation in the Working Group advising Prime Minister, Tony Blair, on the development of warnings in preparation for the G8 meeting held in Scotland in June 2005.

Findings

The conclusions of the paper grow from variety of experiences that both the authors have gained in working for many years in the field of disaster management. A number of requirements emerge from the experience such as specific administrative measures, political will, scientific knowledge and the development of tsunami safety culture.

Practical implications

The paper provides an overview of some of the social and administrative measures needed to enable scientific warnings to be disseminated and applied at every level to protect people and their property.

Originality/value

The message of this paper is an attempt to stress the importance of the totality of an effective warning system. At present, the scientific side has secured vital attention. But this has to be complemented with the social and administrative elements on which all scientific detection depends. The authors argue that these neglected safety elements require urgent attention if a full safety system is to function effectively.
