    M6.2 Earthquake Hits Tokyo - Caution Advisable


    This morning Tokyo was awoken by a large M6.2 earthquake centred just off Tokyo Bay.


    Izu Oshima is an island that rarely experiences earthquakes.  However in 1923 when it experienced a quake 2 magnitudes higher it resulted in one of the worlds worst disasters!


    Killing over 140,000 people the M7.9 BIG ONE hit Tokyo and unleashed devastating Tsunami on Japan.


    Main shocks are often proceeded by quakes around 2 magnitudes smaller, which would result in an M8.2 quake if this M6.2 quake we just experienced is a foreshock! 


    When the M9.0 earthquake devastated japan in 2011 it was proceeded by an M7.2 (3 magnitudes lower than the main event) earthquake 2 days early.  However, little importance was given to that foreshock and Japan was totally unprepared for the devastation that ensued!


    And so, once again, caution would seem highly advisable, however, as the Japan Metrological Agency only gives warnings and advisories for the Tokai Earthquake it has again not released any advisories or warnings in relation to the Kanto region.


    Just 2 days ago the number of earthquakes spiked from an average of about 5 a day all the way up to 40!  Highlighting a possible series of anomalies in the countries seismicity.
