Update Feb 8, 2013 The region continues to be hammered with major tremors - The picture added below show only those greater than 6.0 as of 9 am Friday.
Just hours ago a massive 8.0 Earthquake rocked the South Pacific. A Tsunami watch has been issued for the South Pacific regions up to and including Hawaii. Read about it here
Over the past seven days the USGS (US Geological Service) recorded 34 major tremors in the region, all above 5.0 on the Richter Scale. During the entire 23 day period prior to this past week no earthquakes were recorded measuring greater then 5.0 where 23 major shake events, seven greater than 6.0, occurred during the week prior to the major event a few hours ago.
Plate tectonics and the study around the predictability of these events have proven to be very difficult. Sometimes a major earthquake occurs without any warning and then the region experiences numerous aftershocks. This one proved to have numerous before shocks leading up to the 8.0. As of this composition it too has been followed by 10 aftershocks greater than 5.0.
Mother Nature and/or God is that way. One must always be prepared for the unexpected. The Pacific Rim experiences thousands of Earthquakes every month. Some large, most small, but the plates are always moving.
There is a theory on how the plates face pressure and tension from other plates moving. As one plate slips, causing the ground the shake, another plate is set up with more stress or less stress at the same moment.
Therefore the Pacific Rim can be seen as a game of Pong. As the ball hits it bounces off into a different direction only to hit again and bounce back again in another direction, all on the same playing surface. In this case the surface is the Pacific Ocean and the perimeter walls of the game are all the lands and Nations surrounding the Ocean.
British Columbia is one of those locations. Be prepared. Anyone who states they know when the next one will occur is not being honest. It could be tomorrow and it may not happen in our lifetime.
