美国地质调查局的一位科学家于1982年6月在费城召开的美国地球物理联合会的会议上宣布了产生地震光的一种可能的机制。正在加利福尼亚和同事们一起工作的拜尔利(James D.Byerlee)曾提出过地震板块相互磨擦所产生的热足以使该断层上的岩石和土壤中的水发生汽化而产生一种电荷。由此引起的这种电荷场与雷暴中的相似,会产生强烈的放电现象,使得在离震中70英里的地方都能看见地光。拜尔利解释说,这种机制与火山喷发时常
A scientist at the United States Geological Survey announced a possible mechanism for generating seismic light at a meeting of the American Geophysical Union in Philadelphia in June 1982. James D. Baylee, who is working with his colleagues in California, has suggested that the heat generated by the mutual friction of seismic plates is sufficient to vaporize the water in the rocks and soil in the fault to produce a charge. The resulting charge field, similar to that in a thunderstorm, produces a strong discharge that allows light to be seen 70 miles from the epicenter. Bailey explained that this mechanism is often associated with volcanic eruptions
