NTHMP Island Caucus

The NTHMP Island Caucus was formed on approval of the NTHMP Coordinating Committee at its meeting of February 5, 2016.

The Island Caucus was created to provide a forum for the members of the NTHMP who are on islands or have significant island chains (Alaska) to focus on the risks associated with the development and maintenance of a comprehensive tsunami preparedness and response program that meets the needs of the islands. Although attendance at Island Caucus gatherings is open to all, the core members are representatives from areas listed below.

There are many others who provide valued guidance and support: Pacific Tsunami Warning Center, National Weather Service, International Tsunami Information Center, University of Hawaii, University of Puerto Rico, and the Caribbean Tsunami Warning Program, as well as other NTHMP partners.
