EQC have released all of the geotech factual reports from the surveys carried out following the September 4 earthquake.
There is nothing on the website to say whether these surveys need to be redone because of the February 22 earthquake, or to what extent they might be considered still relevant. Chances are they are still partially relevant because they look at the way land has been built up over time. What will be missing is the changes to the soil as a result of the February 22nd earthquake and the consequential lateral spread and liquifaction.
No additional interpretative reports have been released
The list of all the factual reports can be found here. The Avonside report is here.
