Then the next instance of subduction occurs years later, and the lip of the subducting plate pushes further, but what happens to the rumpling that occurred the first time?
下一个例子是几年后发生俯沖,该俯沖板块的顶端进一步推动,但第一次起皱时会发生什么情况?
This process continues, with the original rumpling repeatedly being rumpled until the point arrives where it is above any sliding of one plate over another, riding like foam on a wave.
