LocWolf, I'd be more concerned with the arrival of Apophis (Wormwood) which some NASA whistleblowers say may hit around San Diego. That would cause ripples in the earth's crust in all directions. Yellowstone, Three Sisters, New Madrid, etc could all be triggered, not to mention a column of water blowing up into space turning into a cloud of ice crystals that spread out and reflect sun light like the Younger Dryas event. Now that would cause 7 years of desolation.
