This map shows liquefacction susceptibility for Oregon calculated following the methods of FEMA's 2011 HAZUS-MH MR4 technical manual. The map was prepared in support of a series of ground motion and ground failure maps for a scenario Magnitude 9.0 Cascadia Subduction Earthquake developed by the Oregon Department of Geology aand Mineral Industries. The scenario maps were prepared for the Oregon Sesimic Safety Policy Advisory Commission for its use in preparing a report to the 77th Oregon Legislative Assembly entitled " The Oregon Resilience Plan; Reducing Risk and Improving Recovery for the Next Cascadia Earthquake and Tsunami". |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This map uses the methods of HAZUS-MH MR4 (FEMA 2011 in references) to create new liquefaction suceptibility data for Oregon. HAZUS assigns susceptibility classes based on geology. For this map, the geology was primarily taken from OGDC 5 (Ma and others, 2009, in refernces) and SLIDO 2 (Burns and others, 2011 in references) with some coming from published liquefaction studies. The methods and data used to make this map are described in detail in : </SPAN><SPAN><SPAN>Madin, I.P., and Burns, W.J., 2013, Ground motion, ground deformation, tsunami inundation, coseismic subsidence, and damage potential maps for the 2012 Oregon Resilience Plan for Cascadia Subduction Zone Earthquakes; Oregon Department of Geology and Mineral Industries Open-File Report O-13-06.</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
