Te Whanganui-a-Tara Wellington City

The capital city lies within the collision zone between two tectonic plates and sits on top of one of the zone's most active geological faults - the Wellington Fault. Many other active fault lines pass through and near Wellington City, which makes for a significant earthquake and tsunami risk.
