Seismic and Aseismic Slip of the 2020 Mw 7.4 Oaxaca, Mexico, Earthquake: Implications for the Kinematic Characteristics and Frictional Behaviors in the Mexican Subduction Zone

The coseismic surface deformation caused by the 2020 Oaxaca earthquake and postseismic deformation are described in Tang et al. paper “Geodetic Constraints on Modeling of Coseismic Slip and Postseismic Afterslip of the 2020 Mw 7.4 Oaxaca Earthquake”. Files named "coseismic-asc InSAR.txt", "coseismic-des InSAR.txt", and "coseismic-GPS.txt" are coseismic displacements obtained from ascending InSAR, descending InSAR, and GPS data. Files named "postseismic-10.txt", "postseismic-30.txt", and "postseismic-60.txt" show the 10-day, 30-day, and 60-day surface deformation after the mainshock. File named "aftershocks.xlsx" is the earthquake catalog 60 days after the mainshock from Servicio Sismológico Nacional. File named "slip_coseismic.dat" is the coseismic slip distribution. Files named "10-day afterslip.dat", "30-day afterslip.dat", and "60-day afterslip.dat" are the afterslip distribution 10 days, 30 days, and 60 days after the mainshock, respectively.

本数据集涵盖2020年瓦哈卡地震的同震地表形变与震后形变相关内容，相关研究细节已在Tang等人发表的论文《2020年Mw7.4级瓦哈卡地震同震滑动与震后余滑模拟的大地测量约束》（Geodetic Constraints on Modeling of Coseismic Slip and Postseismic Afterslip of the 2020 Mw 7.4 Oaxaca Earthquake）中予以阐述。其中，文件"coseismic-asc InSAR.txt"、"coseismic-des InSAR.txt"及"coseismic-GPS.txt"分别为通过升轨合成孔径雷达干涉测量（Interferometric Synthetic Aperture Radar，InSAR）、降轨InSAR与全球定位系统（Global Positioning System，GPS）数据获取的同震位移数据；文件"postseismic-10.txt"、"postseismic-30.txt"与"postseismic-60.txt"依次展示了主震发生后10天、30天及60天的地表形变结果；文件"aftershocks.xlsx"为墨西哥国家地震服务中心（Servicio Sismológico Nacional）提供的主震后60天余震目录；文件"slip_coseismic.dat"存储同震滑动分布数据；文件"10-day afterslip.dat"、"30-day afterslip.dat"与"60-day afterslip.dat"分别对应主震后10天、30天及60天的余滑分布数据。
