he IUGG Commission on Geophysical Risk and Sustainability will join other national and international organizations to support a Coordinating Group for the development of a GNSS based Early Warning System (GTEWS) for the Oceania Region of the South Pacific. I will examine the state of GTEWS technology, its motivation, and the planning underway to explore the development of GTEWS for the South Pacific Region. The IUGG 2015 General Assembly Resolution #4 called upon IUGG membership to work toward the implementation of a Pacific GTEWS as an augment to existing tsunami warning systems. The Group on Earth Observation (GEO), the UN International Committee on GNSS (ICG) and 17 agencies from 12 countries have joined the IUGG in calling for the implementation of GTEWS. Currently GTEWS are prototype national systems. A Pacific Basin system remains elusive largely due to the reluctance to share mesoscale real time GNSS data and the need for station upgrades. The IUGG, GEO and the ICG will address these challenges through a cooperative effort amongst the nations of the South Pacific, international and national organizations, and the private sector. Australia and New Zealand are operating high quality real time GNSS networks and analysis centers. However, there is little intra-regional networking amongst the nations of Oceania. We seek a regional GTEWS network that will serve as a prototype for the development of a Pacific-wide GTEWS capability. (Ref: GTEWS 2017)
