The following paper outlines a method of identifying controls on the distribution of postglacial alpine sediments in the Selwyn Mountains using a Geographic Information System (GIS) as a vehicle to analyze surficial geology maps, bedrock geology maps, and topographical data. Postglacial alpine sediments in this region include talus, rock glaciers, alluvial fans and Neoglacial till and the spatial distribution of these sediments is controlled by factors such as lithological properties and site characteristics which in turn influence weathering and erosion. As a result, the sediment distribution may give clues about the bedrock weathering and site conditions. The method of cross tabulation is a powerful tool that can provide insight into the spatial patterns of landforms, and processes such as sediment accumulation and landscape denudation. It allows an examination of the distribution of bedrock and surficial geology units with respect to each other and to other map variables such as elevation, slope and aspect. The analysis of the spatial distribution of sediment and the calculation of rates of landscape denudation for different bedrock units then require the use of a G.I.S. Preliminary results suggest that rates of denudation are controlled by a number of factors including bedrock type and site conditions such as elevation and aspect.

Detailed information about foundation requirements is available on the Ministry of Business, Innovation and Employment (MBIE)website.Technical category information is provided on behalf of the Ministry for Business, Innovation and Employment (MBIE) and was the best information available at the time of publication on Canterbury Maps in 2017. A technical category (1, 2 or 3) was assigned to residential properties on flat land in parts of Christchurch City, and Selwyn and Waimakariri districts by MBIE following the 2010/11 earthquakes. The technical categories were established to provide guidance on appropriate geotechnical assessments and foundation solutions for house repairs and reconstruction during the earthquake recovery. The technical categories were intended to have a limited life and were not intended to be updated over time. Details of any work done on an individual property since 2010 to reduce the liquefaction susceptibility of the land, or investigations that show the land meets the definition of another technical category, should be provided to prospective buyers, insurance companies or Christchurch City Council, Waimakariri District Council or Selwyn District Council.Published in the gazetted Land Use Recovery Plan 6/12/2013 https://cera.govt.nz/recovery-strategy/built-environment/land-use-recovery-planTechnical Category 1 (TC 1)Land that was classified Technical Category 1 (TC1) was suitable for homes to be repaired or rebuilt after the 2010/11 Canterbury earthquakes.TC1 land generally did not experience liquefaction-related land damage or settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is unlikely on TC1 land during significant future earthquakes. Standard foundations for concrete slabs or timber floors are considered adequate to address liquefaction hazard for house repairs and rebuilds on TC1 land, but normal consenting requirements still apply (e.g. to confirm suitable ground bearing strength and assess all other hazards).Technical Category 2 (TC 2)Land that was classified Technical Category 2 (TC2) was suitable for homes to be repaired or rebuilt after the 2010/11 Canterbury earthquakes. TC2 land may have experienced liquefaction-related land damage and settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is possible on TC2 land in future significant earthquakes. While TC2 land is considered suitable for residential construction, stronger foundations are required for house repairs and rebuilds. This may include standard timber piled foundations for houses with lightweight cladding and roofing and suspended timber floors or enhanced concrete foundations.Technical Category 3 (TC 3)TC3 land experienced liquefaction-related land damage and settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is possible on TC3 land in future significant earthquakes. While TC3 land is considered suitable for residential construction, site-specific geotechnical investigation and specific engineering foundation design are required for house repairs and rebuilds.There are no one-size-fits-all foundation solution for repairs or rebuilds on TC3 land. Site-specific geotechnical investigations will identify the best foundation for the repair or rebuild to reduce the risk of property damage or injury in future earthquakes. This may include deep foundation piles or ground improvement work.N/A - Port Hills & Banks PeninsulaProperties in parts of the Port Hills and Banks Peninsula have not been given a Technical Category. This is because properties in the hill areas have always required a site-specific foundation design and are not generally subject to liquefaction or lateral spread.Normal consenting procedures will apply in these areas.N/A - Rural & UnmappedProperties in rural areas or beyond the extent of land damage mapping, and properties in parts of the Port Hills and Banks Peninsula have not been given a Technical Category.Normal consenting procedures will apply in these areas.N/A - Urban NonresidentialTechnical Category not applicable means that non-residential properties in urban areas, properties in rural areas or beyond the extent of land damage mapping, and properties in the Port Hills and Banks Peninsula have not been given a Technical Category.Normal consenting procedures will apply in these areas.Red Zone (Port Hills)Red Zone (Port Hills) are areas where the threat to life from cliff collapse or rocks rolling downhill was considered unacceptable following the 2010/11 Canterbury earthquakes. The areas were defined by the Canterbury Earthquake Recovery Authority (CERA). The Crown offered to purchase properties in these areas from the owners, and the properties that were sold to the Crown are now administered by Land Information New Zealand (LINZ) and/or Christchurch City Council. You can find more information on the LINZ website LINZ website. Some properties were not sold to the Crown and in some cases the owners have subsequently installed mitigation works to reduce the cliff collapse or rockfall risk to an acceptable level. Details of any work done to reduce the cliff collapse or rockfall risk to individual properties should be provided to prospective buyers and insurers.Red Zone (Port Hills) areas within Christchurch City are now part of Christchurch City Council’s slope instability hazard management areas. You can find more information on these management areas in Chapter 5 of the Christchurch District Plan, and find more information on Port Hills slope stability on the Christchurch City Council website.Red Zone Christchurch & WaimakariThe Red Zone (Flat Land) areas are where the Crown offered to purchase properties from the owners after 2010/11 Canterbury earthquakes. The Government considered that making the land suitable to build on again and repairing roads and underground services in these areas would be very expensive and take a very long time. It gave property owners in these areas the option to sell their properties to the Crown so that they could resettle more quickly. The areas were defined by the Canterbury Earthquake Recovery Authority (CERA) and the properties that were sold to the Crown are now administered by Land Information New Zealand (LINZ). You can find more information on the LINZ website. Red zone flat land areas within Christchurch City are now part of Christchurch City Council’s Specific Purpose (Flat Land) Recovery Zone. You can find more information on this zone on the Christchurch District Plan.CCC Liquefaction & CERA InformationIn 2019 Christchurch City Council completed a liquefaction hazard study , encompassing the Christchurch urban area, which uses the extensive information about ground conditions gathered since the 2010/11 Canterbury earthquakes and follows the most recent national liquefaction guidance. This includes an updated liquefaction vulnerability map, and an online tool which helps to visualise an area’s vulnerability to liquefaction under different conditions. For details visit the CCC liquefaction information website. You can find out more information about the inherited responsibilities of the Canterbury Earthquake Recovery Authority (CERA) on the Department of the Prime Minister and Cabinet website.

Fischer, B.J. and Pierce, K.L., 2019. GIS compilation for the bedrock geology of part of the Misty Creek paleo-embayment, Mackenzie Mountains (NTS 106B); Northwest Territories Geological Survey, NWT Open Report 2019-001, digital files and appendices.This publication contains the data files used to create NWT Open File 2016-01 (PDF map), Bedrock geology of part of the Misty Creek paleo-embayment, Mackenzie Mountains (NTS 106B). This map derives from fieldwork undertaken by the Northwest Territories Geological Survey (NTGS) as part of the Selma project (from Selwyn-Mackenzie shale basins), as well as re-interpretation of pre-existing data of the Geological Survey of Canada (GSC) and the mineral exploration industry. The Selma project was designed to improve understanding of the basinal strata of map sheet 106B. The basinal strata include strata of both the Lower Paleozoic Misty Creek embayment and the Mid-Paleozoic post-Selwyn basin.NWT Open Report 2019-001 contains information on data sources related to this dataset and additional geological interpretation.
