【摘要】 根据全球地震和火山的分布特征,发现全球的地震和火山具有相似的活动区,其活动区与板块运动密切相关.全球的地震和火山活动区大致可以分为大陆活动区、大洋活动区和俯冲-碰撞带.根据近一个世纪内地震和火山发生强度的大小,将全球的地震和火山活动划分为四个时期,通过分析全球地震和火山分布的平均维度曲线,发现地震和火山在时空上具有同步变化的特征,这很可能与板块的运动密切相关,但局部却显示出不一致性.更多还原

【Abstract】 According to the distribution characteristics of global earthquakes and volcanoes,it’s found that global earthquakes and volcanoes have similar active regions.And the activity regions are closely related to plate movement.The activity regions of global earthquakes and volcanoes can be roughly divided into active continental area,active oceanic area and subduction-collision zone.On the basis of the intensity of earthquakes and volcanoes,activities of the global earthquakes and volcanoes over the past century are divided into four periods.By analyzing the average latitude curves of global earthquakes and volcanoes,it’s concluded that earthquakes and volcanoes have the feature of synchronization changes in time and space.This is likely to be intimately bound with plate movement,but locality shows inconsistency.更多还原
