Several principal tasks will be carried out related to mitigation and response and recovery including: (a) evaluating the effectiveness of pre- earthquake housing damage mitigation programs already in existence, (b) examining the various factors motivating housing owners to retrofit, (c) modeling the expected demands for post- earthquake emergency assistance, and (d) examining the relative time periods involved for the repair or replacement of uninhabitable units. The effort will include workshops, issuing reports and articles, as well as posting summary information on the organization's Internet site.
