2011 Dates of Destruction? March 19, May 21, Oct. 21

Two seismologists quoted in an article on the website Life's Little Mysteries (a sister site of Space.com) said that just as the moon's gravity has an effect on Earth tides, it can also have a minimal effect on the land in what is known as "land tides" or "solid Earth tides." Ultimately, ocean tides and land tides can have an effect upon seismic activity. [Wow, gravity of a body in close proximity and 1/6th the size of our planet might tug on the delicate, cracked, plates and sub-plates floating on the core of our world, which might even trigger some event that was about to pop anyway? WHAT A SURPRISE!]
