1. Tsunami Use Case Tsunami modelling and early warning systems for near source areas (Mediterranean, Juan de Fuca) -> mutual need for tsunami event field data and modeling to deepen our experience in testing methodology and developing real-time data processing sensor registry is available from EMSO, form of data/metadata exposure for CoopEUS is being worked out as OOI interface develops

2. Tsunami Use Case a working workshop will be held in San Francisco, adjacent to AGU 2014, involving key people from EMSO, OOI, and ONC (and possibly other international tsunami experts) to address the following: – Sensors: agree on settings; gap analysis of sensor coverage – Data: compare/harmonise/align sensor metadata, and registries; data policy and access – Modeling: collaborative framework for testing already available algorithms for tsunami detection
