Christchurch Earthquake Maps

After the 2010 Canterbury Earthquake, a 7.1 magnitude earthquake near Christchurch, New Zealand, the region has been hit by hundreds of aftershocks - many of them widely felt around Christchurch, and some of which have caused further damage.


The Christchurch Quake Map on this website aims to present a time-lapse visualisation of the earthquake and its aftershocks, primarily to help those outside the affected area understand what those of us in Canterbury are experiencing. It plots earthquake data from GeoNet on a map using the Google Maps API, with the size of the circle denoting the magnitude (the higher the magnitude, the larger the circle) and the colour showing the focal depth (see the legend below the map).
