this is a known phenomenon
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.[5] 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 (110 km) from the epicenter.[6] Earthquake lights were reportedly spotted in Tianshui, Gansu, approximately 400 kilometres (250 mi) north-northeast of the 2008 Sichuan earthquake's epicenter.[7]
During the 2003 Colima earthquake in Mexico, colorful lights were seen in the skies for the duration of the earthquake.[citation needed] During the 2007 Peru earthquake lights were seen in the skies above the sea and filmed by many people.[8] The phenomenon was also observed and caught on film during the 2009 L'Aquila[9][10] and the 2010 Chile earthquakes.[11] Video footage has also recorded this happening during the 9 April 2011 eruption of Sakurajima Volcano, Japan[citation needed]. 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 8 September.[12]
More recent appearances of the phenomenon, along with video footage of the incidents, happened in Sonoma County of California on August 24, 2014,[13] and in Wellington New Zealand on November 14, 2016 where blue flashes like lightning were seen in the night sky, and recorded on several videos.[14] In September 8, 2017, many people reported such sightings in Mexico City after a 8.2 magnitude earthquake with epicenter 460 miles (740 km) away, near Pijijiapan in the state of Chiapas.[15]
Appearances of the earthquake light seem to occur when the quakes have a high magnitude, generally 5 or higher on the Richter scale.[13] There have also been incidents of yellow, ball-shaped lights appearing before earthquakes.[16]
