The time associated with a single shake is called a “period,” a sharp shake with a short cycle is referred to as a "short-period seismic motion," and a slow and large fluctuation with a long period is referred to as a “long-period ground motion.” High-rise buildings commonly resonate with long-period ground motion; especially high-rise floors experience significant sway motion*. In Japan, espe...
