中文摘要
该项目将部署一个由14个三组分海洋组成的阵列, 海底地震仪记录地震, 在北方中大西洋海岭沿着的两个地点,的 目标是:(1)确定地震震源, (2)对位于中谷的沉积物进行物源机制研究 反演P波和S波的走时和衰减 差异;(4)确定地震之间的关系 位置和物源特征,以及构造非均质性 到段长、中值谷宽、轴向地形起伏 地幔布格异常。
英文摘要
This project will deploy an array of 14 three-component ocean- bottom seismometers to record earthquakes for a period of about eight weeks at two sites along the northern Mid-Atlantic Ridge. The objectives are to: (1) locate the hypocenters of earthquakes within the median valley; (2) conduct source mechanism studies of located earthquakes; (3) invert P and S wave travel time and attenuation differences; and (4) define the relationships among earthquakes locations and source characteristics, and structural heterogeneity to segment length, median valley width, axial topographic relief and mantle Bouguer anomaly.
