New Zealand's North and South Islands are moving closer together




Cape Campbell, on the northern tip of New Zealand's South Island, has come closer to the North Island by almost 15 centimeters, according to an expert.

(CNN) – The northern and southern islands of New Zealand are moving closer together after a series of earthquakes in 2016 that have raised the seabed, according to the country's geological organization

The magnitude 7.8 earthquake and its Aftershocks raised the seafloor by a foot and a half as they arrived near Kaikōura on the South Island, exposing rocks and sea life covered with seaweed.

And the islands were resumed Sigrún Hreinsdóttir of the GNS Science Body told the New Zealand news website Stuff.

Cape Campbell, on the northeastern tip of the South Island, is Wellington, a larger city, nearly 15 inches closer to the southern co-North Island than it was before the quake, she said.

Meanwhile, Kaikōura has moved six inches to the east, and the coastal city of Blenheim has moved to the same distance to the northeast.

Wellington itself has moved about two inches to the northeast.

Hreinsdóttir noted that it was difficult to determine which fault was most responsible for the movement and said, "In fact, we have all these creeks and the question is, which is the dominant factor?"

GNS Science has monitored geological movements at several locations in New Zealand since the 2016 earthquake.

This quake dramatically altered the landscape in parts of the South Island and, according to the organization, resulted in 25 breakthrough cracks "One of the most complex earthquakes ever recorded worldwide."

An error in Waipapa Bay caused a vertical shift of three feet as it broke at a speed of about two miles per second.

The biggest slip-up was the rejection of Kekerengu, which appeared to slip 30 feet along its entire length, said Michael Blanpied, who was associated with the USGS Earthquake Hazards Program, and said at the time that two people died.
