B2 100 year return period tabulation of the pre-CES and post-CES severity classification results:

 Table B2.1 - Total number of properties in the Residential Red Zone (red text) and Residential Green Zone (green text) with ILV land damage in each liquefaction vulnerability severity classification for 100 year return period levels of earthquake shaking.  Table B2.2 - Number of properties in the Residential Red Zone (red text) and Residential Green Zone (green text) with ILV land damage and Minor change in liquefaction vulnerability severity in each severity classification for 100 year return period levels of earthquake shaking.  Table B2.3 - Number of properties in the Residential Red Zone (red text) and Residential Green Zone (green text) with ILV land damage and Minor OR Major change in liquefaction vulnerability severity in each severity classification for 100 year return period levels of earthquake shaking.  Table B2.3 - Number of properties in the Residential Red Zone (red text) and Residential Green Zone (green text) with ILV land damage and Major change in liquefaction vulnerability severity in each severity classification for 100 year return period levels of earthquake shaking.

Note that boxes with NA in the tables are properties that are not applicable for the severity classification of the portfolio of properties with ILV land damage at 100 year return period levels of earthquake shaking. The property counts in the tables are based on the QPID database (maintained by Quotable Value Ltd) which existed at the time of the CES. The number of properties/QPIDs does not necessarily represent the number of claims.
