[U04-03] GNSS Tsunami Early Warning: Implementing the Sendai Framework for Disaster Risk Reduction
Keywords:Tsunami, GGOS, GTEWS, GNSS
Though seventeen agencies of twelve nations have endorsed GTEWS enhancement within the Global Geodetic Observing Systems Geohazards Initiative, there is much to be done to take full advantage of this new technology for the Indo-Pacific region. The challenges to GTEWS implementation include national policies on data sharing, commercial and agency programmatic decisions, communications and computing resource allocations, and the technical challenges of integrating GTEWS into existing tsunami warning systems. The Group on Earth Observations has adopted GTEWS enhancement as a goal of its Geodesy4Sendai community activity in response to the UNDRR call to implement the recommendations of the Sendai Framework for Disaster Risk Reduction. This presentation will discuss the recommendations of the GTEWS 2017 workshop and the follow-on GTEWS 2020 workshop focused upon the implementation of GTEWS for the Indo-Pacific.
