This video shows the ruptured Kekerengu Fault, near the coastal town of Kaikoura, following the 7.8 magnitude earthquake that hit New Zealand's South Island.
The quake left a 10-meter (roughly 33 feet) horizontal displacement around 20 miles in length.
Meanwhile, on the coast along the Papatea Fault, rocks were pushed out of the sea by 6 meters (roughly 20 feet).
