地球自转速度变化所产生的动力，可以使地球的岩石圈、水圈、气圈、生物圈物质发生异常性的运动和变化，从而引发地震、海洋灾害、气象灾害和生物灾害；它又使这些灾害彼此之间具有密切的内在联系和大体相同的韵律活动。这一特点在认识自然灾害发生发展规律和进行灾害综合预报时是非常重要的。 The momentum generated by the changing speed of the Earth’s rotation can cause abnormal movements and changes of the Earth’s lithosphere, hydrosphere, balloon and biosphere, which will lead to earthquakes, marine disasters, meteorological disasters and biological disasters; it also makes these disasters Closely interlinked with each other and roughly the same prosodic activity. This feature is very important in understanding the law of occurrence and development of natural disasters and comprehensive forecast of disasters.
