基于经验公式的湖北省历史地震目录修订研究

本文通过对不同版本的历史地震目录的收集和整理，利用已掌握的历史地震资料，结合地震学、地震地质学等相关学科的研究成果，对湖北省历史地震进行了全面、系统地整理和修订。我们收集了湖北省区域内地震地质资料和1990年以来发生地震的现场考察资料，结合当地经济、地质和建筑特点对有感区域的地震烈度进行了重新判定，通过选取多个地区的地震烈度衰减关系，对烈度-震级的对应关系进行重新标定，并利用经验公式对地震目录中部分历史地震的震级、时间等参数进行了修订。本文最终提取并重新确定了15个遗漏的历史地震，另对3个历史地震做出地震参数的校改建议，研究结果对新的地震区划工作和历史地震研究有重要意义。

The revision of historical earthquake catalogue in Hubei province based on empirical equation

Based on the collation of different versions of historical earthquake catalogs, this paper conducted a comprehensive and systematic revision for the historical earthquakes in Hubei by using the historical seismic data as well as research achievements in seismology, earthquake geology and other related disciplines. We collected the regional seismogeological data and the field investigation data of earthquakes occurring in Hubei since 1990, which combining with local economic, geological and architectural characteristics to redetermine the seismic intensity of the sensitive area. The correspondence between seismic intensity and magnitude is re-calibrated by analyzing the seismic intensity attenuation relationship in some regions. The parameters of the magnitude and time of some historical earthquakes in the earthquake catalogue are revised by using the empirical formula. Finally, 15 missing historical earthquakes are extracted and redefined, and 3 other historical earthquakes are revised. The results are of great significance for new seismic zoning and historical earthquake researches.
