Abstract
The cellular mode concept uses simple physical reasoning to treat the response of soft sediments to earthquake shaking. It assumes that discrete areas of the ground, or "cells", have normal modes of vibration, and that each cell has its own natural frequency of vibration. Evidence indicates that shaking effects often relate directly to cell properties. Thus the 1967 Caracas, 1976 Tangshan, 1985 Mexico and 1989 San Francisco earthquakes have damage patterns, liquefaction patterns and instrumental record features which reflect the response of cellular modes. Since the introduction of the concept in 1974 a range of analytical and numerical techniques have been devised to characterize the cells and their response to earthquake shaking.
