| Abstract | Earthquake lights (EQLs) are an atmospheric luminous phenomenon occurring during strong earthquakes and lasting from a fraction of a second to a few minutes [e.g., 1]. In accordance with eyewitness reports [2] one of the types of the EQLs exhibits similarities with the blue glow observed in St. Elmo's fire (corona) occurring during thunderstorms. Laboratory experiments [3] demonstrate that rocks subjected to stress force can generate electric currents. During earthquakes these currents can deliver significant amounts of net positive charge to the ground-air interface leading to enhancements in the electric field and corona discharges around tall ground objects [4]. It has been suggested recently that the same type of currents can map upward to the ionosphere triggering variations in the total electron content [5]. |
