The reason that there have been so many aftershocks after the 2010 Christchurch earthquake is because bigger earthquakes have not only stronger aftershocks, but more of them. Aftershocks happen because when an earthquake occurs, the earth's plates hardly ever settle into a stable position straight away. So, the newly moved rock has to be settle.
Chile lies on the boundry of two techtonic plates, the South American plate and the Nazca plate. It has experienced many earthquakes. The two most notable are the 1960 Great Chilean earthquake also know as the Valdivia earthquake. It was the largest earthquake ever measured and recorded. It was also the location for the 5th largest recorded earthquake, the 2010 Chilean earthquake of February 27th, 2010.
