Focal Mechanism Solutions Dataset of Local Earthquakes (1951-2020) in Egypt

This file incorporates the final gathered and analyzed focal mechanisms for local earthquakes that present moment magnitudes equal to or greater than 3.0, and occurred from 1951 to 2020, in Egypt. The current dataset comprises a total number of 462 focal mechanism solutions covering the spatial region from 21° to 34°N latitudes and from 24° to 38°E longitudes. Reported parameters for each included earthquake in this dataset are the origin time (year-month-date) and date (hour-minute-second), coordinates in terms of longitude and latitude, depth and magnitude values, faulting parameters for the two nodal planes in terms of the strike, dip and rake angles, azimuth and plunge of the principal strain axes (P-,T-, and B-axes), as well as the faulting type (Normal “NF”, Normal with strike-slip component “NS”, Strike-slip “SS”, Reverse “TF”, Reverse with strike-slip component “TS”, or Undefined “U” faulting).

本数据集收录了1951年至2020年间埃及境内发生的、矩震级（moment magnitude）不低于3.0的天然地震的最终采集并分析得到的震源机制解。本数据集总计包含462个震源机制解，覆盖的空间范围为北纬21°至34°、东经24°至38°。本数据集收录的每一条地震记录对应的参数包括：发震时刻（精确至年-月-日 时-分-秒）、经纬度坐标、震源深度与震级数值、两个节面的走向、倾角、滑动角等断层参数、主应变轴（P轴、T轴与B轴）的方位角与倾伏角，以及断层类型（正断层"NF"、含走滑分量的正断层"NS"、走滑断层"SS"、逆断层"TF"、含走滑分量的逆断层"TS"，或未定义"U"断层）。
