Tectonic setting New Zealand lies along the boundary between the Indo-Australian plate and Pacific plates. In the South Island most of the relative displacement between these plates is taken up along a single dextral (right lateral) strike-slip fault with a major reverse component, the Alpine Fault. In the North Island the displacement is mainly taken up along the Hikurangi Subduction Zone, although the remaining dextral strike-slip component of the relative plate motion is accommodated by the North Island Fault System (NIFS), which runs from Wellington, up Hawke's Bay and through to Gisborne and the Bay of Plenty. The 1863 earthquake is believed to have occurred outside the Mohaka Fault, just west of Waipukurau.March 2022 Reported effects Residents living in Hawke's Bay at the time reported numerous landslides, as well as vast soil liquefaction and the opening of large fissures in the ground. Residents also reported overturned furniture and snapped chimneys. According to The Hawke's Bay Herald, there was considerable damage to stock in stores and hotels, and although some chimney bricks fell through roofs, no major injuries were reported. Houses were shaken off their piles. Aftershocks continued at short intervals for the rest of the morning.http://wildland.owdjim.gen.nz/?p=85 Wild Land Wildland.owdjim.gen.nz 12 January 2015 Outside of Hawke's Bay, the earthquake woke many people in Wellington, causing minor structural damage but had a large toll on personal belongings. The Wellington Independent noted that the initial earthquake lasted 30–40 seconds and was followed by several smaller aftershocks. In Wanganui, the earthquake was described as the sharpest shock in both duration and severity since the magnitude 8.2 Wairarapa earthquake in 1855. However, no damage was sustained. In Nelson the earthquake was felt as three sharp shocks in quick succession at about 1:20 a.m. In Gisborne the earthquake was felt, but did not cause any damage.http://nzetc.victoria.ac.nz/tm/scholarly/tei-MacHist-t1-body-d38-d9-d1.html Earthquakes, Seismic Waves, Floods and Droughts Nzetc.victoria.ac.nz 12 January 2015 See also List of earthquakes in New Zealand List of historical earthquakes References Category:Earthquakes in New Zealand Hawke's Bay Hawke's Bay earthquake Category:History of Hawke's Bay Category:February 1863 in Oceania Category:1863 disasters in New Zealand
