Some of the sites around the world are ancient volcanic sites, such as Nan Madol. Others were ancient comet strikes and others yet CME solar flare strikes.

The import being these are all part of Earth's most destructive phases encapsulated within our solar micro-nova event.
A time when Earth is under attack as well as our sun. Earth will wobble like a drunkard and expand as if pregnant.

This expansion has fooled many - ocean floor scars left to heal, but reopen during her expansion (under attack-time frame) when the time is right.
