Abstract

This article continues studies on advancing the methodology for seismic zoning of the Russian Federation. Computational technologies for probabilistic seismic hazard analysis (PSHA), which have been used extensively worldwide, were developed at the end of the 20th and have barely changed over the past 20 years. As a rule, recent studies have focused on refining the models included in the calculation: the source zone model and the seismic impact model. Global practice utilizes the PSHA technology both for the construction of general seismic zoning (GSZ) maps and at the stage of detailed investigations in engineering and seismological surveys for building particular objects. At the same time, in accordance with the scale of a survey, detailed elaboration of the source zone model is done and the seismic impact model based on regional data is adjusted. In 2010–2016, while updating GSZ-97 and developing the GSZ-2012/2014/2016 maps, S.A. Peretokin and E.V. Bodyakin, under the supervision of V.I. Ulomov, upgraded the related software. The new user interface was called EAST-2016. This article illustrates the use of GSZ-97 technology at the stage of refining initial seismicity assessments. A case study of the southern coast of the Crimean Peninsula has been used to adjust the seismic impact model of an extended source based on regional macroseismic data. The obtained parameters can be used to refine the initial seismicity of the specified territory.

根据区域宏观地震数据调整扩展震源地震影响模型

摘要

本文继续进行有关推进俄罗斯联邦地震分区方法的研究。概率地震危险性分析（PSHA）的计算技术已在20世纪末发展起来，在过去20年中几乎没有变化，这种技术已在全球范围内广泛使用。通常，最近的研究集中在完善计算中包括的模型：震源区模型和地震影响模型。全球实践均利用PSHA技术构建一般地震区带（GSZ）地图，并在针对特定建筑物的工程和地震勘测的详细调查阶段。同时，根据调查规模，对源区模型进行了详细的阐述，并对基于区域数据的地震影响模型进行了调整。在2010–2016年，在更新GSZ-97和开发GSZ-2012 / 2014/2016地图的同时，SA Peretokin和EV Bodyakin在VI Ulomov的监督下升级了相关软件。新的用户界面称为EAST-2016。本文说明了在完善初始地震活动性评估阶段使用GSZ-97技术的情况。克里米亚半岛南部海岸的一个案例研究已用于根据区域宏观地震数据调整扩展源的地震影响模型。所获得的参数可用于完善指定区域的初始地震活动性。本文说明了在完善初始地震活动性评估阶段使用GSZ-97技术的情况。克里米亚半岛南部海岸的一个案例研究已用于根据区域宏观地震数据调整扩展源的地震影响模型。所获得的参数可用于完善指定区域的初始地震活动性。本文说明了在完善初始地震活动性评估阶段使用GSZ-97技术的情况。克里米亚半岛南部海岸的一个案例研究已用于根据区域宏观地震数据调整扩展源的地震影响模型。所获得的参数可用于完善指定区域的初始地震活动性。
