Chilean Earthquake of 27 Feb 2010

The rarity of large (Mw > 8.0) earthquakes makes it challenging for seismologists to study the dynamic processes that occur when faults fail. The Chilean Earthquake of 27 Feb 2010 is estimated to have a moment magnitude (Mw) of 8.8 – only 5 earthquakes are known to have been larger.

Eric Kiser, over at Harvard, has done some preliminary modeling, which lets scientists get a glimpse of how the dynamic rupture might have occurred on 27 Feb 2010. There is an extremely nice animated GIF on his site that I dare not poach, and I recommend getting a higher resolution image of it.
