Earthquakes
Wellington was seriously damaged by a series of earthquakes in 1848 and another earthquake in 1855. The event in 1855 is now known as the Wairarapa earthquake and occurred on a fault line to the north or east of Wellington. It was probably the most powerful earthquake in recorded New Zealand history, with an estimated magnitude of at least 8.2. It caused vertical movements of 2 to 3 metres to land over a large area, including raising an area of land out of the harbour and turning it into a tidal swamp. Much of this land was subsequently reclaimed and is now part of Wellington's central business district. This is the reason why the street named Lambton Quay is now 100-200 metres from the harbour. There are a number of plaques set into the footpath on Lambton Quay, at major intersections, that indicate where the shoreline was located in 1840 to show the extent of the uplift.
The area has high seismic activity even by New Zealand standards, with a major fault line running through the centre of the city and several others nearby. Several hundred more minor fault lines have been identified within the urban area. Typically at least one earthquake is noticed by the inhabitants every year, particularly in the high-rise office buildings in the city. For many years after the 1855 earthquake, the majority of buildings constructed in Wellington were made entirely from wood. The recently restored Government Buildings, between the Railway Station and Parliament Buildings is the largest wooden office building in the Southern Hemisphere. While masonry and structural steel have subsequently been used in building construction, especially office buildings, timber framing is still the primary structural component of almost all residential construction. Residents also place their hopes of survival in good building regulations, which were gradually tightened during the 20th century.
NZ's Capital
In 1865 Wellington became the capital of New Zealand, replacing Auckland where William Hobson had established his capital in 1840. Parliament first sat in Wellington on 7 July, 1862, but the city did not become the official capital for some time. In November 1863 Alfred Domett moved a resolution before Parliament (in Auckland) that “it has become necessary that the seat of government...should be transferred to some suitable locality in Cook Strait.” Apparently there was concern that the southern regions, where the goldfields were located, would form a separate colony. Commissioners from Australia were of the opinion that Wellington was suitable because of its harbour and central location. Parliament officially sat in Wellington for the first time on 26 July, 1865. The population of Wellington was then 4900. (reference Phillip Temple, Wellington Yesterday).
Wellington attained city status in 1886.
