First of all ,let me make it clear that ,for 2011 I have not yet posted any dates. However, if you look at my previous posts and my web page (http://earthquakeprediction.webs.com/) you will find a term -cycle quakes-. When a major quakes occurs ,there will be a major aftershock after 7 and half days ie between 7th and 8th day as well as on 14/15th day.
The santiago,Argentina quake occured between 7th and 8th day of major quake of 25th December 2010
The prbable dates for 2011 quakes (7+) will be posted soon on this blog as well as on my web page
