Earthquake lights linked to rift zones

[knocker]

 

A new catalogue of earthquake lights — mysterious glows sometimes reported before or during seismic shaking — finds that they happen most often in geological rift environments, where the ground is pulling apart. The work is the latest to tackle the enigmatic lights, which have been described by eyewitnesses for centuries but are yet to be fully explained by scientists

Perhaps something akin to northern lights? - charged particles, electro-magnetic forces
