Other mountains may be raised by earthquakes, which fracture the Earth's crust and can displace enough rock to produce block mountains.
另一些山脉可能是由地震引起的，地震使地壳断裂，并移动足够的岩石，从而形成块状山脉。

The volcanic activities have relations to the heat-flow upwelling, crust thinning, upper mantle and lower crust melting, and upward movement of the melt materials along the block boundaries.
火山活动与热流上涌、地壳拉伸减薄、上地幔及下地壳物质熔融并沿块体边界向浅部上移有关。

The seismic wave velocity in the crust and at the top of the upper mantle in the plateau is slower than that in the Indian subcontinent and Alxa block.
