此火山带赋存于阿留申岛弧系内,此一岛弧系明显由呈链状的水上和水下山系组成,由南阿拉斯加到堪察加东西延伸达3400km。它形成外突的岛弧,其曲率半径1200km,宽度100到 250km。从构造方面来理解,阿留申岛弧系包括共轭的阿留申海槽和白令海的相邻地段。在此情况下,它经常被视为现代地槽(1963,1971,1972;1975; This volcanic belt occurs within the Aleutian island arc system, which obviously consists of a chain of watery and subterranean pedigrees extending from South Alaska to Kamchatka to an extent of 3400 km. It forms an outlying island arc with a radius of curvature of 1200km and a width of 100 to 250km. From a structural point of view, the Aleutian arc system includes the Contiguous Aleutian Channel and adjacent parts of the Bering Sea. In this case, it is often regarded as a modern trough (1963, 1971, 1972; 1975;
