大地震可以产生造山作用,但是也可以触发滑坡从而消磨自然景观。根据2008年汶川地震的分析表明,滑坡毁坏了更多的地形,高于地壳抬升的方量。多山地带的地形演化被最简单地看作地形建造的构造过程与地形破坏并带走沉积物的侵蚀过程之间的竞争。在构造活动的山脉,这些侵蚀过程主要包括陡峭河流的下切和物质输送、以滑坡和冰川磨损形式的大规模物质输送。每种作用的贡献随时间而变化,受气候的变化而不同。当构造抬升的过程超过侵蚀过程时,造山带生长;当两者平衡时,造山带保持稳定;而当侵蚀超过抬升
Large earthquakes can produce orogenic effects, but can also trigger landslides to polish the natural landscape. According to the analysis of the 2008 Wenchuan earthquake, the landslide destroyed more terrain than the amount of crustal uplift. The mountainous terrain evolution is most simply seen as a competition between the topographic construction of the structure and the destruction of the terrain by the erosion of the sediment. In constructing active mountains, these erosion processes mainly include undercutting and material transport of steep rivers, large-scale material transport in the form of landslides and glacial wear. The contribution of each role varies with time and varies with the climate. Orogenic belts grow when tectonic uplifting process exceeds erosion process; orogenic belt remains stable when both are balanced; and when erosion exceeds overlifting
