在过去的20年里,世界各地由于预想不到的灾害的发生而导致许多人员伤亡及财产的损失。很多学者认为大型灾害的发生主要是地球变暖,诱发异常气候所致。若将此视为长期原因,那么由于地壳运动增加而引起地震、海啸、火山爆发等可以视为短期原因。
In the past two decades, many people have been killed, injured and property has been lost in the world due to unforeseen disasters. Many scholars believe that the occurrence of major disasters is mainly due to the warming of the earth and the induction of abnormal climate. If this is considered to be a long-term cause, then earthquakes, tsunamis and volcanic eruptions due to the increase of crustal movement can be regarded as short-term causes.
