Fault Line Wakes Up: New Zealand Could Be DESTROYED By Massive 9.0 Earthquake

A 2016 earthquake has awoken a fault line that was thought to be dormant. Now that it’s becoming active, fears have arisen that New Zealand could be destroyed by a massive 9.0 magnitude earthquake.

The devastating Kaikura earthquake in 2016 has resurrected the Hikurangi subductionzone where two tectonic plates clash and one is pushed down. Geologists are now warning that this trench could cause a massive earthquake on the ocean floor, and could trigger other 9.0 magnitude earthquakes and tsunamis that will reach the western coast of the islands in just seven minutes.

The Australian plate is heading north while the Pacific plate is heading west, and the combination of these motions means that the Pacific plate, which includes much of the South Island, is moving relative to the Australian plate at a rate of about 40millimeterss each year in a southwesterly direction.

Ursula Cochran, from the science firm GNS, told The Marlborough Express: “We need to think Japan 2011 basically, because if our whole plate boundary ruptured it would be a magnitude-9 earthquake.” The Great East Japan Earthquake and resulting tsunami smashed through the country’s north-eastern coast killing almost 16,000 people and destroying the lives of thousands more. It also triggered a major ongoing crisis at the Fukushima nuclear plant.

“One of the biggest hazards of that kind of earthquake is the tsunami that is triggered by a fault rupture offshore.,” Cochran added. “We know from tsunami modeling from a hypothetical earthquake from the Hikurangi subduction zone that the travel times could be very short to the coast, so seven minutes for some of the south Wairarapa coast.”

One year after it struck, scientists are also warning that the Kaikoura quake was not the “big one” for the Hikurangi subduction zone. The quake on the Hikurangi subduction zone was
