It seems that internal structures and discontinuities in the litosphere have an essential influence on the litocpheric derofmation like faulting or earthquakes. The micromorphic continuum providies a good framework to study the continnum with microstructure, such as earthquake structures. Here we briefly introduce micromorphic continuum to consider the earthquake structures (e.g., rotational wave). Then the equlibrium equation in terms of the displacements (the Navier equation) is derived from this micromorphic continuum. This equation is the generalization of Laplace equation in terms of displacements and can lead to some Laplace equation such as the local diffusion-like conservation equations. Moreover, these conservation fields bear the fractal properties of fracturing in the lithosphere in the form of facults or earthquakes. Finally some scalling laws of faults or eartquakes are discussed.
