SYDNEY, May 3 (UPI) — Australian scientists are using a math model to find the 10 optimal sites where Indian Ocean tsunami detection buoys and sea-level monitors should be placed.
The scientists, led by Professor Lindsay Botten and senior lecturer Layna Groen at the University of Technology in Sydney, said the model could save time and money, as well as provide warning for the maximum number of people should a potentially devastating tsunami occur again in the Indian Ocean.
The researchers, along with Katerina Blazek, formerly with the engineering and sciences firm Sinclair Knight Mers, said the U.N. Intergovernmental Oceanographic Commission planned the establishment of the Indian Ocean Tsunami Warning and Mitigation System, consisting of seismic detectors, sea-level monitors and deep-sea pressure sensors attached to deep ocean buoys.
Few detection buoys are yet in place and a number of sea-level monitoring stations must still be constructed. The scientists said their study should help decision makers determine where the remaining buoys should be placed. And they said the same mathematical modeling could be applied to tsunami detection in the Atlantic Ocean, as well as the Mediterranean, Caribbean and Black Seas.
“The imperative for this is made clear in the … Intergovernmental Oceanographic Committee estimate that by the year 2025, three-quarters of the world’s population will be living in coastal areas,” the researchers said.
The study appears in the International Journal of Operational Research.
