<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Ostler Fault Hazard Area for the Mackenzie District Plan. This revised version of the Ostler Fault Hazard Area replaces the Ostler Fault Hazard Area developed for the Mackenzie District Plan in 2010. </SPAN></P><P><SPAN>The Ostler Fault Hazard Area is the area potentially at risk of surface fault rupture (breaking and buckling of the ground) associated with an earthquake on the Ostler Fault. Surface fault rupture only affects a narrow zone tens of metres wide along the fault. It is a different hazard from earthquake shaking, which would affect a much wider area.</SPAN></P><P><SPAN>The hazard area has been derived by placing buffers around the mapped 'distributed' and 'well-defined' fault deformation associated with the Ostler Fault. A 35 metre buffer was placed either side of the Haybarn strands of the Ostler Fault, on the western side of the Pukaki Canal. A 50 metre buffer was placed on the downthrown side of the Ruataniwha strands of the Ostler Fault on the eastern and northern side of the Pukaki Canal, and a 100 metre buffer on the upthrown side. This additional buffer width is to take account of the more complex deformation associated with the Ruataniwha strand, and the greater likelihood of deformation on the upthrown side of fault strands than the downthrown.</SPAN></P><P><SPAN>Accompanying report is Jack, H., 2023, </SPAN><SPAN STYLE="font-style:italic;">Revised Ostler Fault mapping for the Mackenzie District Plan.</SPAN><SPAN>Environment Canterbury science report.</SPAN></P></DIV></DIV></DIV>
