陆域地震的前兆现象(英文)
|
摘要
地震是人类目前还难以控制的自然灾害.但在多数剧烈的陆域地震发生以前,伴随地下岩层中应力和应变能的积累,在相关的区域可能出现一些地震前兆,例如地面倾斜、前震、地电和地下水异常、动物行为异常等.因此,研究前兆现象与未来地震之间的内在联系,有助于防震减灾工作.
Earthquakes are a hazard that humans cannot control.But before severe continental earthguakes,as stress and strain energy accumulate in the subsurface rock layers,various earthguake precursors(gradual tilting of land,foreshock,geoelectricity and groundwater changes,erratic animal behavior)may occur in the affected area.Consequently,researches on the inherent connection between precursory phenomena and potential seismic activities in the future are beneficial.
