SKS measurements and null measurements for seismic stations in Eritrea and Yemen
收藏资源简介:
These files relate to "Channelized mantle flow through the Afar Triple Junction and around the Arabian plate: evidence from seismic anisotropy" by Gauntlett et al. (2024). Original seismic waveforms are from the Eritrea Seismic Project (Hammond et al., 2011) and the Young Conjugate Margins Lab in the Gulf of Aden network (Leroy et al., 2007) and are publicly available throughEarthScope Data Services. The repository consists of three files: SKS_ALL.csv SKS_NULL_ALL.csv stations_all.csv The first file provides individual shear-wave splitting results reported in the study for the SKS phase. The columns are as follows: Station longitude Station latitude Orientation of the fast split shear wave (φ) Time delay between the fast and slow shear waves (dt) Error in phi Error in dt Event longitude Event latitude Event backazimuth Distance in degrees from event-station Event code Station name The second file provides information on null results reported in the study, where no shear-wave splitting is observed for the SKS phase. The columns are as follows: Station longitude Station latitude Event longitude Event latitude Event backazimuth Distance in degrees from event-station Event code Station name The station file contains the station name, the station latitude, station longitude and station elevation in km above sea level.
本数据集关联Gauntlett等人(2024)发表的学术论文《穿过阿法尔三联点(Afar Triple Junction)及环绕阿拉伯板块(Arabian plate)的通道式地幔流:来自地震各向异性(seismic anisotropy)的证据》。原始地震波形数据源自厄立特里亚地震项目(Hammond等人,2011)以及亚丁湾年轻共轭边缘实验室台网(Leroy等人,2007),并可通过EarthScope数据服务中心公开获取。 本数据集仓库包含三个文件: SKS_ALL.csv SKS_NULL_ALL.csv stations_all.csv 第一个文件包含本研究中针对SKS震相报告的单条剪切波分裂(shear-wave splitting)结果,各列信息如下: 1. 台站经度 2. 台站纬度 3. 快剪切波偏振方向(φ) 4. 快慢剪切波的时间延迟(dt) 5. φ的误差 6. dt的误差 7. 地震事件经度 8. 地震事件纬度 9. 地震事件反方位角 10. 台站与地震事件间的角距离(单位:度) 11. 地震事件编号 12. 台站名称 第二个文件包含本研究中报告的零结果相关信息,即SKS震相未观测到剪切波分裂的情况,各列信息如下: 1. 台站经度 2. 台站纬度 3. 地震事件经度 4. 地震事件纬度 5. 地震事件反方位角 6. 台站与地震事件间的角距离(单位:度) 7. 地震事件编号 8. 台站名称 台站文件包含台站名称、台站纬度、台站经度以及台站海拔(单位:千米,相对于海平面)。
