While we find the likelihood of a major earthquake and/or other geological events to be remote, we have heard of the so called ‘earthquake lights’ before and feel that their relation to earthquakes to be intriguing.
With that all said, and irregardless of your personal views on the subject,
We strongly suggest a thorough review of your emergency preparations with an eye to earthquake and post-earthquake survival. Water and shelter (as sheltering in place may not be a viable option, requiring you to relocate anywhere from a few hundred yards to several hundred miles.) will be your primary concerns, plan appropriately.
