摘要

本文对台湾地震监测台网的覆盖范围进行了评估。一般网络的能力是适当数量的最佳分布节点的函数。对于这个案例研究,评估是用统计方法进行的,其中包括描述性空间统计与点模式技术的结合。对比地震活动性分布、完整震级分布、活动发震源分布、地震危险性分布和人口分布,分析了地震监测台网节点的空间分布。所有这些数据都可以与地震监测网的目标联系起来;因此,可以反过来使用它们来检索有关网络本身一致性的信息。特别地,我们研究了“实时地震监测网”和“强震观测网”,每一个都有自己的目标,因此分别与地震活动性、发震源、地震危险性和人口分布等与其目的相关的外部信息进行了比较。这种简单可靠的方法显示了台湾建立的网络的高质量。总的来说,它能够提供关于任何类型网络覆盖范围的数量信息,确定可能的关键领域并处理其未来发展问题。

Evaluation of the earthquake monitoring network in Taiwan

Evaluation of the earthquake monitoring network in Taiwan

In this work, we perform an evaluation of the coverage of the earthquake monitoring network of Taiwan. The capability of a general network is a function of an adequate number of optimally distributed nodes. For this case study, the evaluation is performed with a statistical approach which includes descriptive spatial statistics in combination with point pattern techniques. The spatial distribution of the nodes of the earthquake monitoring network is analyzed in comparison with the distribution of seismicity, completeness magnitude, active seismogenic sources, seismic hazard, and population distribution. All these data can be put in relationship with the objectives of an earthquake monitoring network; therefore, they can be used, in turn, to retrieve information about the consistency of the network itself. In particular, we investigate the “Real-time Seismic Monitoring Network” and the “Strong-Motion Earthquake Observation Network,” each one characterized by its own objectives, and therefore respectively compared with external information related to their purposes such as seismicity, seismogenic sources, seismic hazard, and population distribution. This simple and reliable approach reveals the high quality of the networks established in Taiwan. In general, it is able to provide quantitative information on the coverage of any type of network, identifying possible critical areas and addressing their future development.
