The oceans surrounding New Zealand were hit by three powerful earthquakes on March 4. The strongest of the quakes was a powerful 8.1 magnitude tremor which hit near to the Kermadec Islands, 1000km northeast of New Zealand. Residents along the shores of the north of the country’s North Island were issued an evacuation warning as experts feared a major tsunami.

While monstrous waves failed to materialise, locals spotted the after-effects of the tremors in the water as waves rushed in.

In one video, a powerful surge can be seen rushing through the ocean at Tokumaru Bay, along the east coast of the North Island.

In another image, the Mangere Bridge waterfront view in Auckland was void of water as the ocean crept out during the tsunami.

This happens as a tsunami is not typically one wave.

Instead, when an earthquake causes a tsunami, the water usually rushes out before coming back with a vengeance.

This is caused by a sufficient amount of water becoming dislodged near the epicentre of an earthquake.

In this instance, however, the tsunami was not powerful enough to cause any devastation.

Images also show the traffic standstill along roads as many people attempted to flee following evacuation warnings.

Following the earthquakes, New Zealand’s National Emergency Management Agency (NEMA) warned people along the coast to seek higher land, causing mass evacuations.

The agency said: “This evacuation advice overrides the current COVID-19 Alert Level requirements.

“Do not stay at home if you are near the coast and felt the earthquake LONG or STRONG.

“Evacuate immediately to the nearest high ground, out of all tsunami evacuation zones or as far inland as possible.

“Stay two metres away from others if you can and it is safe to do so.

“Do not return until an official all-clear message is given by Civil Defence.

“Walk, run or cycle if at all possible to reduce the chances of getting stuck in traffic congestion.”

However, this was later cancelled and people were allowed to return to their homes.

Still, NEMA told people to retain a sense of caution for the coming hours.

The agency said: “Strong and unusual currents and unpredictable surges will continue for up to another 24 hours.

“People should remain vigilant and take extra precautions with regards to beach and ocean activities.”
