在舒马金和亚卡塔加地震空区,1980—1985年期间的应变积累已用三角测量的方法进行了测量,这两个地震空区被认为是沿阿拉斯加一阿留申岛弧最有可能发生下次俯冲型地震的区域。在舒马金空区未观测到显著的应变积累,但根据相类似的消减带经验和消减过程的简单模型表明,它应该积累了可测的应变。对该观测的最可能的解释是,那里的消减要么 Strain buildup during the period 1980-1985 in the Shumakine and Yaquetaka Earthquakes area has been measured by means of triangulation, which are considered most probable along the Alaska-Aleutian island arc The area where the next subduction earthquake occurs. No significant strain accumulation was observed in the Schumacher void, but a simple model based on similar experience with abatement and abatement processes suggests that it should accumulate measurable strain. The most likely explanation for this observation is where the abatement is either
