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

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.
