Most, but not all, occur at or near plate boundaries. A large number of stress concentrations, a large number of strains (most of which are in the form of earth fractures) occur where two plates diverge, deform or converge relative to each other.
Tension is the main stress at the boundary of different plates. Normal faults and rifts are the main structures associated with ** on divergent plate boundaries. The strongest at diverging plate boundaries are usually relatively shallow, and although they can be destructive, the strongest at diverging plate boundaries are far less powerful than the strongest at converging plate boundaries.
The transition plate boundary is a region dominated by horizontal shear, in which strike-slip faults are the most characteristic fault type. Most of the conversion plate boundaries pass through relatively thin oceanic crust (part of the seafloor structure) and produce relatively shallow ** but with few magnitudes. However, where the transition plate boundary and its strike-slip faults pass through a thicker island crust or a thicker continental crust, more stresses may need to accumulate before the thicker rock blocks break up, so the magnitude of the rock may vary.
Above the transition plate boundary zone confined to thin oceanic crust. This is evident in places like the San Andreas Fault Zone in California, where conversion faults run through the continental crust, where ** sometimes exceeds 7Level 0.
The converging plate boundaries are dominated by compression. The major faults found at the converging plate boundaries are usually thrust faults or thrust faults, including the main thrust fault at the boundary between the two plates and several major thrust faults that are usually roughly parallel to the plate boundary. The strongest ** that has been measured ** is the dive**, which can reach a magnitude of 9Level 0 or higher. All subduction zones in the world exist and occur 9The danger of diving above level 0** and in extreme cases may even trigger a tsunami.
These include the Cascadia subduction zone in northern California and coastal areas of Oregon and Washington, the Aleutian subduction zone in southern Alaska, the Kamchatka subduction zone in the Russian Pacific, the Acapulco subduction zone in the Pacific Ocean south of Mexico, the Mesoamerican subduction zone, the Andean subduction zone, the western Indian Ocean or Caribbean subduction zone, and the subduction zone in Indonesia, Japan, the Philippines, and several other subduction zones in the western and southwestern Pacific Oceans.
