Re: [Geology2] THE SCOTIA SEA keeps rocking with bigger and BIGGER quakes, whats up?

They are probably not aftershocks and probably not related.  Go to Google Earth and enable Earthquakes and it will show decades of quake epicenters.  I just looked at the Nov 17 7+ quake near the Orkney Islands and while there have been several dozen quakes in the trenches to the north and south within the Scotia Sea, this one is by its lonesome so this one doesn't appear related to the other clusters. Enjoy exploring!

I have noticed that The Scotia Sea was listed several times in reports during the last few weeks but one has to look at how close these epicenters are as the sea is rather large and full of faults/trenches etc. Under this area is an extension of the Andes Range on the subducted Pacific plate which takes a  deep salient to the north, east then, south side of the Scotia plate then back to Antarctica along the Palmerland Peninchula .  But running more directly across the Scotia plate are several converging seafloor segments/trenches where these many quakes are plotted.  On casual observation it looks like the Siota plate may be "accordian folding" back on itself.
