The epicentre of the quake was approximately south-south-east of the town of Matata, or north-north-west of Edgecumbe. The intense ground-shaking caused by the earthquake led to a large number of ground surface failures, including sand boils, ridge-top shatters and debris avalanches on steeper slopes. Because of the earthquake, many people left and therefore Edgecumbe's population dropped considerably. Edgecumbe is slowly recovering as it has increased by 21 in the years 2006 to 2013, possibly due to many kiwifruit orchards being affected by PSA.
