Earthquakes in diverse places; the greatest proof of all three. "Diverse" means in places they have never been before and in numerical amounts they have never been seen. In case you are skeptical, these quakes were registered in places they have never been seen and in increased amounts over the years. Jesus said these would be the "birth pangs".

Also it should be noted that there has been a significant increase in seismic monitoring stations around the world. 

The primary purpose of these is to have multiple points on the global map by which they can more accurately pinpoint the location or epicenter of a seismic event.  The reason I have chosen only to look at magnitude 6.0 or greater is that even with a small number of seismic recorders scattered around the earth; a 6.0 or greater quake would have been detected.  

The increase in earthquakes overall (especially the very small ones) should not be seen as prophetically significant as these smaller quakes are now more easily detected and can easily be attributed to the numeric increase in monitoring stations.

** As of January 1, 2006 the detailed documentation for these decades is no longer available on the U.S.G.S. website.  However I am fairly confident that a typical local library should still have this type of record within their archives.
