HF radar optimised for tsunami monitoring

Recent reports have shown high-frequency (HF) radar measurements of tsunami signatures as the disturbance propagates from deep water to shallow water across the edge of the continental shelf. Most HF radars are optimised in various ways to measure seasonal circulation, tidal currents or sub-tidal structures. The new data provide the basis for the design of an optimised HF radar installation for the purpose of monitoring tsunamis and issuing accurate warnings to coastal communities. The optimised system has a long range capability, and it has time and space resolutions to match the features that appear in the expected range for tsunamis.
