为解释板内地震所提出的机制,包括(1)岩石圈板块的纬向漂移;(2)缓慢、隆起区的冷却;(3)由于均衡回跳造成的岩石圈挠曲。板块沿纬度的变化,必定与曲率发生变化的岩石圈表面一致,因为地球是个椭球体。这种必然的调整,产生板内应力。例如,向极点漂移的板块逐渐地压扁,并在内部产生压应力,边缘产生张应力。近赤道的板块的受力情况正 Mechanisms proposed to explain intra-plate earthquakes include (1) latitudinal drift of lithospheric plates; (2) slow, updip cooling; (3) lithospheric deflection due to balanced rebounding. The plate along the latitude changes must be consistent with the curvature of the surface of the lithosphere change, because the earth is an ellipsoid. This inevitable adjustment, resulting in stress within the board. For example, the plates that drift toward the poles are gradually crushed and compressive stresses are generated internally and the edges generate tensile stresses. Equatorial plate force situation is positive
