四川雅安地区地震资料数据库（地震目录数据、地磁台分均值数据）

(1)综合整理了124种原本地震目录，对地震条目逐条进行查证、核对、比较与删重，历时十载，建成了中国及邻近地区集成地震目录信息系统，汇集了71万余条地震目录，时间跨度4000多年，空间范围覆盖中国及周边邻近地区，数据属性包括发震时间、经纬度、各种震级、参数精度以及数据来源等50余项。
(2)本数据集是中国科学院北京十三陵地磁中心台在四川雅安地震前后的地磁观测结果。内容包括雅安4月20日地震前后北京十三陵地磁台分均值数据磁偏角（D）、水平强度（H）和垂直强度（Z）三个要素的分均值。

(1) By comprehensively collating 124 original seismic catalogs and performing verification, cross-checking, comparison and deduplication for every single earthquake entry, we have established an integrated earthquake catalog information system for China and its adjacent regions after a decade of work. This system houses over 710,000 seismic catalog records, spanning a temporal range of more than 4,000 years and covering China and its surrounding neighboring areas. It includes more than 50 data attributes such as earthquake origin time, longitude, latitude, various magnitude scales, parameter accuracy, and data sources.
(2) This dataset consists of geomagnetic observation results collected by the Beijing Ming Tombs Geomagnetic Central Station of the Chinese Academy of Sciences before and after the Ya'an earthquake in Sichuan Province. Specifically, it contains the sub-averaged values of three core geomagnetic parameters: magnetic declination (D), horizontal intensity (H), and vertical intensity (Z), measured at the Beijing Ming Tombs Geomagnetic Station before and after the April 20 Ya'an earthquake.
