There have been thousands of aftershocks following the major earthquakes in Christchurch in 2010 and 2011. These aftershocks occur over a period of time as the Earth's crust adjusts to the initial seismic activity.
There was a major earthquake in Christchurch, New Zealand on February 22, 2011, with over 10,000 aftershocks reported in the following months. The main earthquake caused significant damage and loss of life, and the aftershocks added to the ongoing challenges faced by the community.
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.
