Abstract

The seismic intensity scale is one of the oldest instruments for determining the extent of seismic vibrations. Being initially a descriptive characteristic of seismic impact, intensity has long required only more detailed, thorough consideration and recording of the consequences and manifestations of various primary and secondary effects in earthquakes in order to increase its accuracy. The indicators were changes in the natural environment, the reactions of humans and animals, and the results of the impacts of seismic events on various engineering structures. Obviously, the latter research objects listed in this series have the most variable characteristics over time. The emergence of new building structures and materials had to be reflected in the seismic intensity scales. This is encouraging changes in the scales used and the development of new scales. At the same time, there is the problem of the correlation of earthquake intensity estimates over different seismic intensity scales. The article considers the problem of quantitative assessment of differences in intensity determination according to the MCS, MM, MSK-64, and EMS-98 scales, as well as two new national Russian standards, GOST R 57546–2017 and GOST 34511−2018. Comparison is carried out separately according to the macroseismic and instrumental parts of scales. Macroseismic descriptions of individual points (gradations) is analyzed using indicator object, people, objects, buildings and structures, and natural phenomena. Each indicator is considered separately. For the MCS, MM, and MSK-64 scales, as well as GOST R 57546–2017 and GOST 34511−2018, their instrumental parts were compared. Based on these studies, it was concluded that the macroseismic parts of these scales coincide, with the exception of low estimates of the dimensions of fissures in soils on the MSK-64 scale. Average differences in the descriptions of damage to buildings and structures do not exceed 0.1 points. Significant differences exist in the instrumental parts of MM, MSK-64, and GOST R 57546–2017.

不同地震烈度等级的点之间的相关性

摘要

地震烈度标度是确定地震振动程度的最古老的工具之一。强度最初是地震影响的描述性特征，长期以来只需要更详细，透彻地考虑和记录地震中各种主要和次要影响的后果和表现形式，以提高其准确性。指标是自然环境的变化，人与动物的反应以及地震事件对各种工程结构的影响的结果。显然，本系列中列出的后者的研究对象具有随时间变化最大的特征。新建筑结构和材料的出现必须在地震烈度标度中得到反映。这令人鼓舞，改变了使用的秤并开发了新秤。同时，存在地震烈度估计在不同地震烈度等级上的相关性的问题。本文考虑了根据MCS，MM，MSK-64和EMS-98量表以及两个新的俄罗斯国家标准GOST R 57546-2017和GOST 34511-2018对强度确定的差异进行定量评估的问题。根据量表的宏观地震部分和仪器部分分别进行比较。使用指示物，人员，物体，建筑物和结构以及自然现象来分析各个点（渐变）的宏观地震描述。每个指标都单独考虑。对于MCS，MM和MSK-64秤，以及GOST R 57546-2017和GOST 34511-2018，他们的乐器部分进行了比较。基于这些研究，得出的结论是，这些尺度的宏观地震部分是重合的，但对MSK-64尺度的土壤中裂隙尺寸的估计值较低。建筑物和构筑物损坏的描述中的平均差异不超过0.1分。MM，MSK-64和GOST R 57546–2017的仪器部件之间存在显着差异。
