According to Brian Dunning researchers should be concerned about the fact that there are no documented " confirmed observations " of earthquake lights . It is a red flag that there is no consistency of what they are , when they happen and where they happen . It is likely that there " is not one , known , proven phenomenon " . However , a significant amount of video footage has surfaced since the advent of sites like YouTube that claim to represent this — one example being the 2017 Mexico earthquake — although no consistent explanation has been agreed upon . There is also a " staggering volume of literature ... hardly any of these papers agree on anything ... I 'm forced to wonder how many of these eager researchers are familiar with Hyman 's Categorical Imperative : ' Do not try to explain something until you are sure there is something to be explained ' " . Dunning 's final conclusion is that until there is " pending decent evidence " be skeptical of claims of earthquake lights
