摘要:
国家地震烈度速报和预警工程实施后,地震台网密度将发生很大变化,这将对地震烈度速报产生影响。本文以台湾简易烈度计网(P-alert)记录到的高雄M6.7级地震为基础,模拟了全国重点预警区、日本和美国等四种密度的台网,通过比较和分析四种台网的烈度速报结果,研究台网密度变化对地震烈度速报造成的影响,并讨论可能存在的问题。结果表明:台站分布均匀的情况下,台间距越小,控制烈度空间分布的总体趋势越好;密度较高的台网能更好勾画地震能量的释放过程,有助于评判破坏性地震中断层的破裂过程和方向等参数。本文研究结果可为国家工程中烈度速报研究提供一定参考和借鉴。
Abstract:
The density of seismic networkwill be greatly changed after the national seismic intensity rapid reporting and earthquake early warning project.The article based on the event of an M6.7 earthquake in Kaohsiung, Taiwan,which recorded by low-cost sensors network consists of P-alert sensors in Taiwan, then we simulatedfour seismic network with different station spacing such as the national key early warning area, network of Japan and the US network. After that we compared and analyzed the influence of the change ofnetwork density for seismic intensity fast report, possible problems are discussed.The results show thatunder the condition of well-distributed station density, a high-density seismic networkis conducive to map the details of intensity distribution. A higher density network is better able to sketch the process of seismic energy release, present the rupture process and direction of a big earthquake. The results can give some hints for the research on intensity fast report in the national program.
