Liquefaction potential in the Wellington Region urban areas. On 14 November 2016 a complex magnitude 7.8 earthquake, caused by rupture on multiple faults across north Canterbury and Kaikōura. Piers Chamberlain on 07/03/2011 03:36, Wellington earthquake risk map - a Tableau data visualisation. You may use this work for commercial purposes. New Zealand sits on the boundary between the Indo-Australian and Pacific tectonic plates, means that we get a large number of earthquakes. A maximum of 100 earthquakes are displayed. Calculations between each of these fields were carried out on a record by record (or grid centroid) basis.The calculations then followed for each hazard:• calculate the damage for each item of infrastructure for each hazard, based on the damage ratios given in Tables 6 through 10.• modify the liquefaction damage based on an assessed likelihood that liquefaction will occur in the area• total the damage for each hazard• add the damage for each hazard at each cell centroid to get the total damage due to combinations of hazard, a combined hazard index (CHI).These CHI values were then grouped into the severity using the CHI_HAZ_GR field, which was symbolised as the SEVERITY field. This dataset is a compilation of the "liquefaction potential" ArcInfo coverage series with accompanying notes (Publication WRC/PP-T-93/73). This can mean that there is more opportunity for a fire to start and spread. Imported on Feb. 22, 2012 A building with a 50%NBS seismic rating would be expected to withstand, to a similar level of reliability, … An added attribute "Severity" differs slightly to the "SED_CODE" attribute. This Combined Earthquake hazard shapefile is a compilation of all After a large earthquake, there is likely to be damage to buildings and infrastructure. Wellington earthquake risk map - a Tableau data visualisation. Map publication reference: WRC/RP-T-96/15 For notes on how this coverage was created refer to: Mapping methodology and Risk Mitigation Measures Publication: WRC/RP-T-96/22. The 2010–11 Canterbury earthquakes are outside the areas of greatest statistical risk of high ground shaking. This Combined Earthquake hazard shapefile is a compilation of all "combined earthquake hazard" ArcInfo coverages in major urban areas of the Wellington Region. About 14,000 earthquakes occur in and around the country each year, of which between 150 … You can zoom out with or reset view with Revert All. Region. Read more about Fire Following Earthquake.

New Zealand’s largest ever earthquake was the magnitude 8.2–8.3 quake that struck on 23 January 1855. Note: where a building listed has the term ’Section 124 Served’, this means earthquake-prone building notices issued under Section 66 of the Building Act 1991 have been reissued a notice under Section 124 of the Building Act 2004 requiring strengthening. Esri JSON In the below Tableau data visualisation you might want to take a look at your home and work addresses and assess the known issues in your immediate surroundings. In 1942 the Wairarapa was shaken by a magnitude 7.2 earthquake on 24 June and then a 7.0 on 2 August, both caused extensive local damage. SEVERITY, ... A 2-D database table (cell table, with 10m grids) that covers each map area was constructed. You must attribute the creator in your own works. A maximum of 100 earthquakes are displayed. Wellington Fault: Conditional Probability of Rupture Likelihood of a really big earthquake on the Wellington Fault (accounting for) • Elapsed time since most recent rupture Slightly younger than previously thought (~ 300 years ago) • Timing of older ruptures Slightly less frequent than previously thought (~ every 800-1000 years) CHI_HAZ_GR, Large (magnitude 7+) events are thought to occur once every 500 years and very large (magnitude 8+) events every 1000 or more years. Liquefaction potential in the Wellington Region urban areas. In modern homes, doorways are no stronger than any other part of the structure and usually have doors that can swing and injure you.

Greater Wellington works with the community towards achieving a sustainable economy and environment. 1: Area of tsunami inundation 2: 20m buffer along major fault traces 3: Ground shaking 4: Liquefaction potential 5: Slope failure. Map … The earthquake could be the only warning of a tsunami! The earthquake caused damage to the city including uplift of the harbour, a tsunami in the Wellington harbour and numerous landslides around the region. Liquefaction happens where some soils, particularly silt or sandy soils, become saturated as a result of ground shaking, which causes the soil to lose strength. in, NZGD2000 / New Zealand Transverse Mercator 2000, SED_CODE, On Friday the Wellington City Council released a list of Buildings in Wellington that they consider an Earthquake risk. in, NZGD2000 / New Zealand Transverse Mercator 2000. i.e. Refer also to Consultant Ian R Brown Associates at www.irba.co.nz/. Most buildings will remain standing during a large earthquake. See Drop, Cover, Hold for information on safe places in an earthquake. The map uses colour codes to show the relative level of hazard to areas in Porirua. The map series is one of Greater Wellington’s natural hazard education and awareness initiatives. The Wellington region is regularly shaken by small and medium-sized earthquakes. The Wellington region has been subject to a number of large earthquakes in the past 175 years. In Wellington, office buildings are designed and built to withstand, with a high level of reliability, earthquake shaking with a return period of one in 500 years. The Wellington region is crossed by a number of major faults, including the Wairarapa, Wellington and Ohariu faults. by Piers Chamberlain on 07/03/2011 03:36 Tweet; While our Performance Engineering team is usually more concerned with systems and software, the recent events in Christchurch have made us all think a … Earthquakes produce ground shaking and can also cause tsunamis, landslides and liquefaction. This dataset is a compilation of the "liquefaction potential" ArcInfo coverage series with accompanying notes (Publication WRC/PP-T-93/73). The combined earthquake hazard map is a generalised map of earthquake hazard refl ecting possible effects on a typical range of facilities (buildings, roads, services, etc). CHI. Further information on earthquakes is available from: Phone: 04 830 4279 You must not release derivatives of this work. We are responsible for the region - Wellington, Kapiti, Wairarapa - and... All these cities have experienced severe earthquakes since European settlement.
