Cloud Iridescence Pictures

Showcasing cool pictures of cloud iridescence or commonly known as 'Earthquake lights'. They are produced from magnetic field fluctuations affecting ions in the atmosphere (much like auroras or “northern lights”) from stresses on crystals such as quartz in the base-rock. They occur in times of tectonic stress, earthquakes for example, hence the name.
