Optimising the location of tsunami detection buoys and sea-level monitors in the Indian Ocean

Abstract

In the wake of the 2004 Boxing Day tsunami disaster, a global response to implement a tsunami warning system in the Indian Ocean became imperative. Steps in this direction were initiated in 2005 with plans for the deployment of up to 24 tsunami detection buoys. The purpose of this paper is to investigate the optimal placement of tsunami detection buoys and sea-level monitors, in order to provide warning to the greatest population potentially affected. We adopt a mathematical programming approach to examine this problem. It is determined that 10 sites are essential in ensuring that the maximum population can be warned. This has implications for construction and maintenance of the tsunami warning system in the Indian Ocean. Copyright © 2010 Inderscience Enterprises Ltd
