河北形变观测资料映震能力浅析

Analysis of Earthquake Reflection Based on the Hebei Deformation Observation Data

摘要:

采取Nakai拟合、振幅因子、调和分析和相对均方差等方法，对河北省数字化形变台站的形变观测进行计算和分析。结果表明，河北省形变观测资料中，怀来、易县和宽城的VS垂直摆倾斜仪、DSQ水管倾斜仪和SS-Y伸缩仪观测资料对河北范围内的中强以上地震有中、短期映震能力。

Abstract:

This paper calculates and analyses the deformation observation data observed at Hebei province. The moderate and strong earthquakes in Hebei area are analyzed adopting the methods of Nakai fitting, amplitude factor, harmonic analysis and relative mean square deviation.The results show that the deformation data of vertical pendulum tilmeter、water tube tiltmeter and strain tide of Huailai、Yixian and Kuancheng in Hebei province have medium and short term reflecting earthquake ability for moderate strong earthquakes of the scope of Hebei.
