摘　　要：本文尝试以地史学和力学视角,探索地震成因和气候变化原因。分析地震成因,须研究地壳的运动规律、运动情况和受力情况;任何时期的地壳运动、地震,都主要由陆壳分合引发;现阶段的地壳运动、地震,主要是因冈瓦纳裂解(惯性,与地幔对流无关)。并非俯冲、地幔流动引发地壳运动,而是地壳运动引发俯冲、地幔流动。俯冲是因洋壳被动受压,而并非洋壳主动扩张。岩石圈破坏规律遵循“强度理论”[1],构造地震均发生于岩石圈的“危险点”或“危险截面”。古生代三次大灭绝和多次冰川活动、中生代早期全球干旱广布,均是因海西运动。日本岛、台湾省、菲律宾、郯庐断裂带等地震频发,华北岩石圈减薄、东亚大地幔楔、安的列斯弧、马里亚纳海沟、秘鲁海沟、智利海沟、东太平洋海丘、秘鲁寒流、厄尔尼诺现象等,均是因南美洲顺时针扭转(南美洲西海岸承受巨大扭力)。陆壳分合引发地壳形变、地热和水气调节,是全球气候变化、冰川消长的最主要原因。冰川形成,减弱寒冷和潮湿;冰川消融,减弱炎热和干旱。This article attempts to explore the causes of earthquakes and climate change from Historical Geology and mechanics.This article holds that,in order to analyze the causes of earthquakes,it is necessary to study the law of crustal movement,and study the movement and the force of the earths crust;in any period,both crustal movement and earthquakes are mainly caused by“continental crust separation and closure”(continental crust movement);at this stage,crustal movementand earthquakes are mainly due to the separation of Gondwana(the inertia of thecontinental crust expansion and cracking,not because ofMantle convection).It is not subduction or mantle flow that causes crustal movement,but rather crustal movement that causes subduction,mantle fl ow.Subduction is due to passive compression of the ocean crust,rather than active expansion of the ocean crust.The failure law of the lithosphere follows thestrength theory[1]of material mechanics,tectonic earthquakes must occur in thedangerous pointordangerous cross-sectionof the lithosphere.In the Paleozoic era,threeMass extinctions,multiple glacial activities,and in the early Mesozoic era,global drought was widespread,all of these are caused by Hercynian Movement.Japan,Taiwan Province,the Philippines,Tanlu Fault Zone,etc.,frequent earthquakes,the thinning of the North China lithosphere and the formation of East Asian Mantle wedge,the formation of Antilles Arc,the formation of Mariana Trench,Peru Trench,Chile Trench,etc.,the formation of East Pacifi c Hill,the formation of Peru Current,El Nino phenomena,etc.,all of these are caused by the clockwise rotation of South America(the west coast of South America bears great twisting force).Continental crust separation and closuretriggers crustal deformation,geothermal andWater and gas adjustment,which are the main cause of global climate change,glacier growth and decline.Glacier formation,weakening cold and humidity;Glaciers ablation,weakening hot and dry.
