由政府地震调查委员会公布的涵盖全国的地震动预测图(以下称概率预测图),是根据对象地震的发生概率及该地震带来的危险性,计算出一定时限内的地震烈度期望值,并且在边长1km的正方形网格上表示出来。作为表示方式表示出受特定烈度以上振动袭击的概率,并且根据特定概率把造成一定 The earthquake prediction map (hereinafter referred to as the probability prediction map) covering the whole country published by the Government Seismic Survey Committee calculates the expected value of earthquake intensity within a certain period of time based on the occurrence probability of the target earthquake and the danger posed by the earthquake, and at A square grid of 1km is shown on the grid. As a representation of the probability of a particular intensity above the vibration attack, and according to a certain probability to cause certain
