A methodology to optimize the design of an offshore tsunami network array is presented, allowing determination of the placement of sensors to be used in a tsunami early warning system framework. The method improves on previous sensor location methods by integrating three commonly used tsunami forecast performance indicators as a measure of the predictive accuracy through a single cost function. The joint use of different tsunami parameters allows for a network that is less subject to bias found when using a single parameter. The resulting network performance was tested using a set of synthetic target scenarios and also verified against a model of the 2014 Pisagua event, suggesting that having such a network in place could have provided meaningful information for the hazard assessment. The small number of sensors required (three spanning nearly 700 km of the Northern Chile coast) may be useful in implementing such networks in places where funding of denser arrays is difficult.

一种用于放置海啸传感器网络的多参数方法

提出了一种优化海上海啸网络阵列设计的方法，允许确定要在海啸预警系统框架中使用的传感器的位置。该方法通过集成三个常用的海啸预测性能指标作为预测准确性的度量，通过单个成本函数改进了以前的传感器定位方法。不同海啸参数的联合使用允许网络在使用单个参数时较少受到偏差的影响。由此产生的网络性能使用一组综合目标场景进行测试，并针对 2014 年比萨瓜事件的模型进行了验证，表明拥有这样的网络可以为危害评估提供有意义的信息。
