    The two Mag 6 earthquakes were preceded by a mag 5.3 and followed by two Mag 5.3 earthquakes.

    Is there a more recent page of stats than the one you presented as it stops at 2012 curiously?

    (or maybe we're just past the end of the world as we know it)

    I just grabbed that page to show you the numbers ( note the comments in the red box near the top of the page)
    The yearly averages haven't changed in the last 4 years when looked at over the long term

    Unfortunately the USGS www site is not as good as it was prior to 2012 and many features have either disappeared or are there but no longer work. I guess the lack of govt funding has hit home

    the list at the top of this page goes to 2015 for world wide events
