Medium-Term Strategy


The PTWS Medium Term Strategy (PTWS MTS) was approved at the ICG/PTWS-XXIII in February, 2009.  It describes the basic directions towards continuously improving the Pacific Tsunami Warning & Mitigation System to meet stakeholder requirements during the period 2009-2013. It focuses on describing general, common but essential, strategic objectives to ensure an effective and efficient, tsunami warning and mitigation system that is interoperable wherever possible with the other ocean basins and seas. The PTWS working group structure derives from the PTWS MTS and is described in the PTWS Working group Structure. And details of the methods to accomplish these strategic objectives are defined in the PTWS Implementation Plan.
