这项研究将通过安装在密苏里州到马萨诸塞州的20个宽带pascal地震仪的密集线性阵列来研究上地幔,包括俯冲板块和核心-地幔边界,距离为1736公里。该阵列记录的地震数据将大大提高结构的分辨率,如太平洋下的核心-地幔边界,阿留申群岛、千岛群岛-堪察加半岛、秘鲁-智利和中美洲的板块穿透深度,以及北美和加勒比地区的上地幔细节。这项工作将对地球对流引擎的细节以及板块和地震的共同驱动力提供重要的新见解。***
英文摘要
9315971 Fischer This research will study the upper mantle, including subducting slabs, and the core-mantle boundary by means of a dense linear array of 20 broad-band PASSCAL seismometers installed from Missouri to Massachusetts, a distance of 1736 km. Data from earthquakes recorded by the array will substantially increase resolution of structures such as the core-mantle boundary under the Pacific, slab penetration depths in the Aleutians, Kuril-Kamchatka, Peru-Chile, and Central America, and the details of the upper mantle under North America and the Caribbean. This work should shed significant new insight into details of the earth's convection engine and resultant driving forces of plates and earthquakes. ***
