    hi guys

    as per title
    Yesterday, 10 March 2014 there was a M 6.8 offshore of northern California in the Mendocino Fracture Zone of the Juan De Fuca Plate

    Just coming in on the seismo right now is another M 6.8, east of the South Sandwich Islands
    right at the southern end of the Atlantic Ocean

    seismo at http://www.sydneystormcity.com/seismograms.htm

    The nthrn Calif can be seen at the top of the display with the new event at the bottom
    the display updates every 5 minutes.
    I'm expecting similar to slightly larger amplitude as the event is a little closer to my sensor
    But variations in propagation can change that

    cheers
    Dave

    its just been downgraded to a M 6.4 by the USGS. released magnitudes do sometimes vary and get updated over the first several hours.
