ed clouds associated with a seismic event, sometimes more than 50 days in advance of the earthquake. Some have even claimed to accurately predict earthquake occurrences by observing clouds.
An earthquake light is an unusual luminous aerial phenomenon that reportedly appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. Once commonly challenged, it was not until photographs were taken during the Matsushiro earthquake swarm in Nagano, Japan (which occurred from 1965 through 1967) that the seismology community acknowledged their occurrence.
The lights are reported to appear while an earthquake is occurring, although there are reports of lights before or after earthquakes, such as reports concerning the 1975 Kalapana earthquake.
They are reported to have shapes similar to those of the auroras, with a white to bluish hue, but occasionally they have been reported having a wider color spectrum. The luminosity is reported to be visible for several seconds, but has also been reported to last for tens of minutes. Accounts of viewable distance from the epicenter varies, in the 1930 Idu earthquake, lights were reported up to 70 miles from the epicenter.
Earthquake lights were reportedly spotted in Tianshui, Gansu, approximately 400 km north-northeast of the earthquake's epicenter. During the 2007 Peru earthquake lights were seen in the skies above the sea and filmed by many people. The phenomenon was also observed and caught on film during the 2009 L'Aquila and the 2010 Chile earthquakes. The phenomenon was also reported around the Amuri Earthquake in New Zealand, that occurred 1 September 1888. The lights were visible in the morning of 1 September in Reefton, and again on the 8th of September.
Earthquake lights are caused by an unknown mechanism. There are numerous theories as to how and why they occur.
One explanation involves intense electric fields created piezoelectrically by tectonic movements of rocks containing quartz.
