Accurate marine forecasts will contribute to a better disaster preparedness and hazard mitigation both at sea and along coastal communities. Public authorities will profit from the real time data and the derived short term forecasts.

For time sensitive applications such as Tsunami Detection this robust on-shore system is well suited due to its high data availability in all weather conditions. The systems are easy to maintain by local experts and are less expensive than in-water sensors.
