摘　　要：云南鲁甸地震自2014年8月3日发生以来,已有几年。鲁甸地震引发不少学者、专家的关注。文章注意到一些与之不被人注意的、看似毫不相干的事件,提出了他们之间存在着内在联系的新观点,希望引起有关部门的重视。(1)云南鲁甸地震是被著名地震学家强祖基教授准确预报了的。强祖基教授根据气象卫星红外图像的异常分布预测地震震级、地震时间及地点。这一情况证明了地震与地球排气作用是有关的。(2)云南鲁甸曾在2002年被朱炳泉教授成功发现了自然铜矿床。自然铜是呈零价的铜元素集合体。铜通常是+1、+2价,要把这种呈+1、+2价的铜离子还原成呈零价的自然铜,需要极还原性的地质地球化学环境,这种环境只有富含氢气的天然气才具有,而这也只有地球深部的天然气才具有上述特点,这是古代二叠纪玄武岩喷发才有的地球化学环境,这是一个奇妙的天然"冶炼"过程,值得地质矿床学家、冶炼学家认真反思!(3)云南丽江—贵州清镇纵剖面的二维地壳速度结构图揭示,在鲁甸地区10~15 km的中地壳具有低速特征,这种低速(也常常是高导的)特征表明中地壳是个塑性层,有巨量的天然气,正是这种天然气的爆炸才导致了鲁甸地震的发生。鲁甸地震与2008年5月四川汶川地震的发生机制是一致的,也与陕西华县8级地震(渭河盆地)、宁夏海源8.5级地震(六盘山盆地)、宁夏银川地震、河北唐山地震、辽宁海城地震等的形成机理是一致的。云南鲁甸地震与地球深部气体之间的成因联系,对地震机理的认识有一定普遍意义。Ludian earthquake in Yunnan,occured on August 3,2014,caused many scholars and experts concern.This paper finds some evidences that are ignored or seemingly unrelated,puts forward new opinions,and hopes to attract the attention of the relevant departments.(1)Ludian earthquake in Yunnan had been accurately predicted by professor Qiang Zuji who is a famous earthquake scientist.According to abnormal distribution of the satellite infrared cloud image,professor Qiang Zuji predicted Ludian earthquake’s magnitude,time and location.This fact proves that the earthquake is related to deep earth degassing.(2)In 2002,Zhu Bingquan,a famous isotope geochemist,discovered the native copper deposit in Ludian.Natural copper is an aggregate of zero valent copper elements,and copper is usually an aggregate of+1 ion or+2 ion,but reduction of geological and geochemical environment has to be needed when+1 ion or+2 copper ion is reduced to zero valent copper ion of native copper.Of cause,everyone knows reduction geochemical environment with rich hydrogen is just offered by natural gas which was Permian basalts erupting in deep earth.The formation of native copper is a wonderful natural“smelting”process,and is worthy of serious reflection on the geological minerals and smelting experts.(3)Two dimensional velocity structure diagram of Yunnan Lijiang-Guizhou Qingzhen profile reveals low velocity features about 10-15 km in the middle crust in Ludian area.These features show that there is plastic layer and a huge amount of natural gas in middle crust,and show Ludian earthquake was been occurred by the natural gas explosion.Ludian earthquake has the same earthquake mechanism with the magnitude 8 Wenchuan earthquake in Sichuan province in China on May 12,2008,the magnitude 8 Huaxian in Shanxi province(located in Weihe basin),the magnitude 8.5 Haiyuan earthquake in Ningxia province(located in Liupanshan basin),Yinchuan earthquake in Ningxia province,Tangshan earthquake,and Haicheng earthquake in Liaoning province.It is an universal signifi
