The high-magnitude earthquake of 27.2.2010 in southern Central Chile closed one of the two remaining seismic gaps at the South American plate boundary. After the quake of Concepcion, the remaining gap in the north of Chile now holds potential for a comparable strong quake and is, thus, moving more and more into the focus of attention.
This earthquake most likely doesn't mean anything, but it is in a significant spot. Who knows when these things decide to rip? I just hope the people on the coast are alerted to the signs of when to run like hell!
