The optimal placement of tsunameters in the Tasman Sea

Abstract

As part of the Australian Tsunami Warning System project, the Australian Bureau of Meteorology deployed two tsunameters in the Tasman Sea. The locations of these tsunameters were initially chosen through determination of an ‘optimal’ location and placing both buoys near this location. There is some justification for relocating these tsunameters and this work presents an analysis to determine the optimum locations for two tsunameters in this area. This takes into account a number of factors, such as international maritime boundaries, provision of the earliest possible tsunami observation times and the ability to detect the largest tsunami amplitudes. Based on the results of the analysis, two specific locations are recommended for the optimal placement of the tsunameters
