7.6 Magnitude Earthquake near the Kermadec Islands

Although probably not a very big deal for many people due to the location of the earthquake, its 7.6 magnitude is still very notable. If we look back to the magnitude 7.6 on July 6th 2011 it created a tsunami.  The Kermadec tsunami on July 6th 2011 was generated by a Mw 7.6 earthquake (29.312°S, 176.204°W ), at 19:03:16 UTC, 163 km (101 miles) E of Raoul Island, Kermadec Islands (according to the USGS). This is almost exactly where today’s 7.6 earthquake occured.  This one will likely not cause a tsunami as it was a little deeper.  Tsunami prediction/update will follow shortly.

The earth is grumbling and producing a larger than average number of earthquakes. Although they do not seem to be that much stronger than normal earthquakes we are seeing some in places that I have never seen a strong (4+ magnitude) earthquake before. What does this all mean? Probably nothing but I have a feeling that we are going to see a few more like this over the next 48 hours.
