The mysterious "UFO lights" may occur at rifts or nearly vertical faults as the crystalline structure of the magmatic stones, subjected to intense pressure, releases electrical energy.
The so called "UFO lights" refers to "earthquake flashes" that occur before or during an earthquake. These flashes appear in a number of different shapes, with one of the most common forms being spheres of light orbs floating through air.
Some have confused the globular luminous air masses with UFOs. For instance, seconds before the 2009 L'Aquila, Italy, earthquake struck, pedestrians saw 10 centimeter high flames of light flickering above the Francesco Crispi Avenue in the town's historical city center.
In 1988, a bright purple-pink globe of light moved through the sky along the St. Lawrence River near the city of Quebec, Canada, 11 days before a powerful quake.

Scientists said the "earthquake lights" are more likely to occur on or near a rift, an elongated depression in the Earth's crust bounded on both sides by normal faults.
Stress-activated mobile electronic charge carriers, termed positive holes, flow swiftly along stress gradients. Upon reaching the surface, they ionize air molecules and generate the observed light.
Continental rift environments now appear to be the common factor associated with earthquake.
Looking back at 65 of the recorded earthquake lights recorded in American and European documents dating from the 1600s, 85 percent appeared spatially on or near rifts.
Robert Thiriault, a geologist with Canadian ministry of natural resources in Quebec says earthquake lights as a pre-earthquake phenomenon, in combination with other types of parameters that vary prior to seismic activity, may one day help forecast the approach of a major quake.

岩浆石的晶体组织在遭受强压之后会释放电能，因此裂缝或垂直的断层处可能会产生神秘的“UFO光束”%ED*ZCeQHs。
所谓的“UFO光束”指地震发生前或震中出现的“地震闪光”uYkx.tCh6W。这些闪光会以不同的形状出现，其中最普遍的形式就是在空中漂浮的光球);sKd5qqMymv。
有些人把这种球状发光气团和UFO混为一谈*PNohF.HkFPG)2X。举例来说，2009年意大利拉奎拉地震发生前几秒，走在弗朗西斯科-克里斯皮大街的行人在该市历史悠久的市中心的上空看到一个直径10厘米的光斑@m&((L!(#tvq。
1988年的一天，有人看到一个紫红色光球在加拿大魁北克附近的圣劳伦斯河上空移动，11天后这里遭到强震袭击|u3gdU*SrLG%1I)。
科学家表示，“地震光”更有可能出现在裂缝及其附近，指以正常断层两侧为界的地壳中的狭长洼地[~^ph*8!rQ2*p.t。
由压力激活的移动电荷载体称为电洞，它们会沿着压力梯度迅速移动~.Pou[N]H=W4BK,Ok|5。在到达表面之后，它们会使空气分子离子化并产生肉眼可看到的光hDbt|qwfKoFeuA|。
大陆裂谷环境是与地震有关的常见因素LE)mpM_[uz-gdq8。
回顾美国和欧洲从17世纪开始记录的65次记载最详细的地光事件，85%显然发生在裂缝上或者附近ia4QMR#T!O8。
魁北克自然资源部的地质学家罗伯特-特里奥尔特表示，作为震前现象的地光与其他类型的震前因素相结合，有一天它们或许有助于预测大地震是否即将发生kNV+v.FFXQ_bH2pYFK。
