Interlinking National Tsunami Early Warning Systems towards Ocean-Wide System-of-Systems Networks
For the integration of national tsunami warning systems to large scale, ocean-wide warning infrastructures a specific protocol has been developed enabling system communication in a system-of-system environment. The proposed communication model incorporates requirements of UNESCO Intergovernmental Oceanic Commission tsunami programme to interlink national tsunami early warning systems. The model...
متن کاملFuture Contribution of HF Radar WERA to Tsunami Early Warning Systems
High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage but also could contribute to the development and improvement of Tsunami Early Warning Systems. The HF radar system WERA is an oceanographic radar placed at the coast and providing simultaneous wide area measurements of ocean surface current fields and sea st...
متن کاملDevelopment of tsunami early warning systems and future challenges
Fostered by and embedded in the general development of information and communications technology (ICT), the evolution of tsunami warning systems (TWS) shows a significant development from seismic-centred to multisensor system architectures using additional sensors (e.g. tide gauges and buoys) for the detection of tsunami waves in the ocean. Currently, the beginning implementation of regional ts...
متن کاملTsunami Arrival Detection with High Frequency (HF) Radar
Quantitative real-time observations of a tsunami have been limited to deep-water, pressure-sensor observations of changes in the sea surface elevation and observations of sea level fluctuations at the coast, which are essentially point measurements. Constrained by these data, models have been used for predictions and warning of the arrival of a tsunami, but to date no system exists for local de...
متن کاملConcept study of radar sensors for near-field tsunami early warning
Off-shore detection of tsunami waves is a critical component of an effective tsunami early warning system (TEWS). Even more critical is the off-shore detection of local tsunamis, namely tsunamis that strike coastal areas within minutes after generation. In this paper we propose new concepts for near-field tsunami early detection, based on innovative and up-to-date microwave remote sensing techn...
