Quite early on, European settlers were faced with the reality of earthquakes in their new and undiscovered land. On 26 May 1840, the new settlement at Port Nicholson was struck by the first of a number of earthquakes and tremors. Early settlers erudite fairly quickly the importance of using fit edifice methods in an earthquake-prone country. The 1848 earthquake, centred in Marlborough, was responsible for immense damage to the brick and masonry buildings in Wellington, and the city was rebuilt chiefly in possessed; consequently it suffered comparatively little damage in the 8.2 magnitude startling of 1855, which upraised the land 2–3m. Many buildings in Hastings and Napier were damaged in the 1931 Hawke's Bay earthquake. New building regulations meant that any new buildings constructed afterwards attempted to take earthquake quake into account in building design.
This is a list of large earthquakes that have occurred in New Zealand. Only earthquakes with a magnitude of 6.0 or greater are listed, except for a few that had a moderate blowy. Aftershocks are not included, unless they were of great meaning or contributed to a death toll, such as the M 6.3 2011 Christchurch earthquake and the M 7.3 aftershock to the 1931 Hawke's Bay earthquake.
"But to have a 7.1 earthquake is unusual," he said. "What you have in New Zealand is a you have the North Island sitting on the Australian structural plate and off the East coast you have the Pacific plate that's pushing beneath the North Island. "That generally causes a hazard of earthquakes along the East coast. What we call it is a plate interface border." The boundary of the Australian and Pacific tectonic diagram, known as the "Ring of Fire," experiences up to 15,000 tremors a year. A 2011 earthquake in the South Island city of Christchurch killed 185 people and caused extensive damage.
While there were no story of injured nation, some buildings secluded water supplies appear to have been damaged in the Gisborne region. Earthquakes in that extent are not uncommon as it's one f the most seismically active areas in New Zealand, GNS seismologist John Ristau told the New Zealand Herald.
It triggered waves of 2.49 meters (8 fact) above usual tide levels, the highest he has seen in his 38 years in New Zealand, Philip Duncan of Weather Watch New Zealand said.
Emergency office inspect a bridge crossing the Waiau River, 110 kms north of Christchurch, as mischief and capture slip cause infrastructure disruption in the aftermath of a 7.5 magnitude earthquake.
In Christchurch, memories of a devastating 6.3-magnitude seism in 2011 are still fresh for many. That quake destroy 185 people and aggrieved thousands, and reduced swaths of the metropolitan's historic area to rubble.
"It started off so small, like the cat flitting in the bed, but then it started building and I had to run to the door. Stuff in the house was falling over and the doors were swaying royally baneful," she said. "Then we decided to get out, and that's when we saw our pool had lost a quantity of water. The earthquake way on for two minutes."
Earthquakes occur often in New Zealand as the country is situated in the collision band between the Indo-Australian and Pacific structural diagram, part of the Pacific Basin Ring of Fire, where many earthquakes and volcanoes occur. Most events occur along the main ranges running from Fiordland in the southwest to East Cape in the northeast. This axis follows the boundary between the Indo-Australian and Pacific plates. Large earthquakes are less common along the central Alpine Fault, where the plates are not subducting and the forces are accommodated in different ways.
The largest city within the highest-wager encircle is the nation's capital, Wellington, followed by Hastings then Napier. All these cities have experienced severe earthquakes since European sediment. About 14,000 earthquakes occur in and around the land each year, of which between 150 and 200 are big enough to be felt. As a spring, New Zealand has very rigid building regulations.
