Possible eclipse and/or earthquake-related preparations?

[Byrd]

While the processes that could produce a spontaneous burst of electromagnetic energy naturally are constantly ongoing in the sun, it seems that this kind of apocalyptic 'warning' is a bit illogical.

A celestial dead-body in between the sun and the planet doesn't "concentrate" or "isolate" any part of that energy in a "focusing" manner.

Unless I am mistaken... perhaps someone can explain how I am misunderstanding the phenomenon.

You're not misunderstanding the phenomenon.  THEY are misunderstanding it.
