地震发光常被假设为大气放电现象.但这难以说明地光的多种颜色和海里所发生的地光.本文提出地光系断层岩石摩擦所直接发出,并非大气放电.它能解释旧假设所不能解释的许多问题.

The earthquake light has long been supposed to be a phenomenon of atmospheric discharge. But it can hardly explain the fact that the earthquake light exhibits many colors and may occur in the sea. This article suggests that the earthquake light is not caused by atmospheric discharge but is a direct radiation from the fault rocks when they arerubbing each other. This new hypothesis oan explain many phenomena that cannot be explained by original suppositions.
