大陆板块的地壳运动导致地震是同时被内部与外部能量触发的。
The crustal movement of the continental plates causing the earthquakes is being triggered by both inner and outer energy forces.
板块运动是地壳和上地幔变形的主要动力来源之一。
Plate motion is one of the major dynamic sources for crustal and mantle deformation.
这个巨大的盆地坐落在火山带内，它是由地壳板块的运动所造成的。
Clenched in the volcanic fist, the huge Basin was created By the motion of crustal plates.
太古宙麻粒岩带就是太古亩地壳发生刚性板块运动的直接产物。
Archaean granulite belts are just the product of plate-tectonic movement of rigid Archaean crust.
来自板块之间相对运动的构造力可以传递到大陆地壳，从而形成了大陆内部的地震应力场。
Tectonic forces from the relative movements between plates are transmitted into the continental crust, and then they create the earthquake generating stress field there.
从板块运动的观点出发，推断了半岛地壳的现代应力场、半岛地区的运动总趋势及其地震发生原因。
The current stress field of the crust, the general movement tendency and the causes of the quakes in the Penisula were inferred based on the plate tectonics.
地壳板块不是以均匀速度移动的，因而，当板块运动较慢时，一个巨大的火山就可“趁机”形成。
The plates of the Earth's crust move at uneven speeds, so when the plate moves slowly, this allows a tremendous volcano to build up.
成矿机理是：区域板块运动使本区在侏罗纪末下地壳形成花岗岩浆熔融层。
The metallogenic mechanism is as follows: in the latest Jurassic, the melting layers of granite magma in the lower crust were formed by the regional plate movement.
地壳从地幔中熔融出来是地质学立论的基础，也是板块构造运动的基本原因。
The Earth's crust being molten and differentiated from the mantle has long been the foundation of geology and also has been taken as the fundamental cause of plate movement.
介绍了关于地球地壳运动的板块学说理论，主要内容是板块运动的动力、板块的划分、板块的分界线，以及板块构造学说与地震的关系。
Plate tectonics is explained, including motive force of crustal movement, delimitation and boundary of plates, relation be-tween plate tectonics and earthquake.
信浓川地震带位于日本大地沟北部，地壳运动十分强烈，区内地震主要沿信浓川流域发生，并密集成带，大地构造上处于日本海板块向本州板块俯冲的边界线上。
The Shinanogawa seismic belt, which is developed in the Northern Fossa Magna, Honshu Island, Japan, extends along the Shinano River bounding the Eurasian Plate and the Okhotsk Plate.
