Maps of lateral spreading and other earthquake effects in Avonside

Courtesy of a blog reader I have discovered a Tonkin & Taylor report on lateral spread in the Avonside Area. The full title is Appendix M: Avonside study area – lateral spreading. The EQC website is currently closed however you can download it from here. On the same website, but this pagehere, is more geotechnical information arising from the Liquefaction Vulnerability Study (mentioned on the blog earlier in the monthhere). There is a huge range of stuff however, as Avonside is the only suburb for which there are detailed maps, possibly nothing informative for those in other Red Zoned areas.The report is a collection of maps that show measured changes in height, and ground surface observations of liquefaction, ground cracking and lateral spread throughout Avonside. The time period of the maps is from September 2010 through to at least the June earthquakes in some cases, and December 2011 in others. The report itself is undated.For those who have some doubts about what happened thi…

Chief Executive of the Insurance Council on various things

On Tuesday Tim Grafton, chief executive of the Insurance Council of New Zealand (ICNZ), gave an address to the Canterbury Branch of The New Zealand Insurance Law Association. His address is available on the ICNZ website here, and is an interesting insight into how insurers see the world. As is his role, he puts the obligations, role and responsibilities of insurers in a positive light. Very positive indeed.Towards the end a significant amount of time is given to what seems like special pleading on the issue of government’s Consumer Law Reform Bill, with a view to having the unfair contracts provisions removed. These provisions apparently represent a threat to the way insurers prefer to do business and there is no evidence of a need for legislation dealing with unfair insurance contracts.For more on unfair contracts legislation there is an Avonside Blog post here.

Wastewater injection caused a 5.7 earthquake in the USA

Injection of water into the ground by the oil industry has been considered a threat to land stability by many. It is dismissed by those who benefit from the oil extraction associated with fracking, and the disposal of waste fluids by injection back into the ground. In the USA a 2011 series of earthquakes (the maximum 5.7) in central Oklahoma have been attributed to the injection of wastewater deep underground. The wastewater was produced as a result of oil extraction in the area: The water linked to the Prague quakes was a by product of oil extraction at one set of oil wells, and was pumped into another set of depleted oil wells targeted for waste storage.A media release from a study involving Columbia University and the US Geological Survey has drawn attention to this connection. As the media release explains, the presence of faults near to where these processes occur are at risk of earthquakes. Part of a scientific media release is below. The full release is on the website Science…

How our insurance policies are going to change, get more complicated, and likely to cost much more.

As this year progresses insurers are changing all existing house insurance policies from “full replacement” to “sum assured”. The change means no one will automatically have a “like for like” insurance policy.The change will require each home owner to work out how much it would cost to replace their house, and insure it for that amount.  It won’t just be the quality of your house that affects the cost of rebuilding it, there are also factors such as the land it is on (e.g. on a slope or a hillside, access ways, retaining walls).Replacement cost will be totally separate from rateable value or market value. If the amount you insure your house for is too little, you won’t get it rebuilt the way it was (and you might even be penalised for being underinsured). Insure for too much and you will being paying too much money and only get what you had.Year after year the sum will need to be adjusted for increasing building costs (they never come down). Do you get the house re-valued each year, o…
