![]() The vertical scale (topographic relief) is exaggerated for clarity. Types Simplified model of phole propagation within an interplate, orogenic tectonic setting in a subduction zone environment (i.e., Andean‐type). Later that year, blue light flashes were also seen in Agadir during the Marrakesh-Safi earthquake. ĭuring the 2023 Turkey–Syria earthquake, multiple lights appeared continuously in Kahramanmaraş and Hatay provinces. This was reported in Mexico News Daily and included one of the videos. Social media users including Webcams de México posted videos of blue lights which seemed to be radiating upward. This phenomenon was observed around 1:18 on 22 September 2022 when a magnitude 6.8 aftershock of the 2022 Michoacán earthquake struck. During the 2022 Fukushima earthquake the phenomena was captured on video from multiple angles. Surveillance video of a local resident captured the moment. ![]() The New York Times reported that "Videos from both Acapulco and Mexico City also showed the night sky lit up with electrical flashes as power lines swayed and buckled." Ī recent one was seen in Qinghai Province, China at 01:45 on 8 January 2022. Instances of this phenomenon appear in videos taken seconds after a 7.1 magnitude earthquake in the city of Acapulco, Mexico, around 20:47 on 7 September 2021. There have also been incidents of yellow, ball-shaped lights appearing before earthquakes. Īppearances of the earthquake light seem to occur when the quakes have a high magnitude, generally 5 or higher on the Richter scale. On September 8, 2017, many people reported such sightings in Mexico City after a 8.2 magnitude earthquake with epicenter 740 km (460 mi) away, near Pijijiapan in the state of Chiapas. More recent appearances of the phenomenon, along with video footage of the incidents, happened in Sonoma County, California on August 24, 2014, 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. The lights were visible in the morning of 1 September in Reefton, and again on 8 September. The phenomenon was also reported around the North Canterbury earthquake in New Zealand, that occurred 1 September 1888. The phenomenon was also observed and caught on film during the 2009 L'Aquila and the 2010 Chile earthquakes. During the 2007 Peru earthquake lights were seen in the skies above the sea and filmed by many people. ĭuring the 2003 Colima earthquake in Mexico, colorful lights were seen in the skies for the duration of the earthquake. Earthquake lights were reportedly spotted in Tianshui, Gansu, approximately 400 km (250 mi) north-northeast of the 2008 Sichuan earthquake's epicenter. ![]() ![]() Accounts of viewable distance from the epicenter varies: in the 1930 Idu earthquake, lights were reported up to 110 km (70 mi) from the epicenter. The luminosity is reported to be visible for several seconds, but has also been reported to last for tens of minutes. 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 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. One of the first records of earthquake lights is from the 869 Jōgan earthquake, described as "strange lights in the sky" in Nihon Sandai Jitsuroku. The phenomenon differs from disruptions to electrical grids – such as arcing power lines – which can produce bright flashes as a result of ground shaking or hazardous weather conditions. There is no broad consensus as to the causes of the phenomenon (or phenomena) involved. ![]() An earthquake light also known as earthquake lightning or earthquake flash is a luminous optical phenomenon that appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. ![]()
