Folks , just sample this intriguing news of New Delhi , the capital of India - from 2 days ago...actually , this sighting followed shortly after a strong tremor that was felt across the Northern part of the subcontinent , though the epicenter of that powerful quake was in Afghanistan , near it's border with Pakistan .
We've often discussed the phenomena of "Earthquake lights" on this forum as part of our discussions on the electromagnetic causes of earthquakes and volcanoes :-
