EARTHLIGHTS

Footage filmed in Wellington, New Zealand, during a 7.8 magnitude earthquake near Christchurch last November shows the night sky lit up with bright colours. Clips show flashes of green, white and blue over a span of a few seconds. Similar accounts of lights in the sky emerged following the previous Christchurch earthquake in 2011. Geologists point out that such lights have been spotted weeks before an earthquake, probably due to stress building in the fault lines. Metro, 14 Nov 2016.
