第二段：In Japan, all modern structures have been designed for seismic activity. Strong building codes are in place for structures of every size. Buildings less than three stories high must have reinforced walls and large foundation slabs. Those of at least three stories have even stricter rules. They are often disconnected from the land around them, a technique called base isolation. They rest on huge rubber or fluid-filled shock absorbers that take the excess energy from an earthquake and convert it into heat. The taller a building is, the greater the risk. Very tall buildings must rest on some sort of shock absorption system. (C)They must be able to sway from side to side without sustaining permanent damage. The top of a building, for example, may need to move as much as three meters in either direction.
