There is so much video documentation of earthquake light now that research into the phenomenon is appearing in scientific journals. For those interested in much more technical detail than what is generally on this website these papers will be of interest.
Dr N E Whitehead has published widely on the subject of earthquake light and precursors. His contributions can be found here:

Dr Whitehead was involved in early work on earthquake-related phenomena as a research assistant to Dr M Ikeya, professor of Earth Sciences at Osaka University, Japan, and published a paper examining statistical probabilities of electromagnetically-generated early waking in 1000 children before the Kobe Earthquake: Unusual Childhood Waking as a Possible Precursor of the 1995 Kobe Earthquake by Motoji Ikeya, and Neil E. Whitehead. This is linked here as a pdf . Dr Ikeya is the author of the book, Earthquakes and Animals
