Disruption characterization and database development and analysis activities conducted for ITER under the aegis of the International Tokamak Physics Activity (ITPA) Topical Group on MHD, Control and Disruption are described. Accomplishments during 2005-2006 include: 1) formation of an International Disruption Database (IDDB) Working Group, 2) implementation of an MDSplus-based IDDB infrastructure for collection and retrieval of disruption-relevant tokamak data, and 3) collection of a "version 1" (v.1) data set from eight elongated-plasma tokamaks. Analysis of the current quench data provides a new recommendation to the ITER International Team for the lower bound on the plasma current decay time in ITER. Plans for further expansion of the scope and content of the IDDB have been identified.
