How can we monitor the wave before its arrivals? (Allgeyer)


Principal investigator

For the time being, tsunami-warning systems operate using a basic "simple" forecast system, using the aggregation of large sub fault models, and observations in deep ocean and tide gauges when available. So far the monitoring of the wave front is difficult due to the large gap between the deep ocean buoys, being too far from the coats, and the coastal wave gauges. The use of GPS buoys close to the coast helps to bridge this gap, such as those installed in Japan. However, there is under utilized potential in the use of sea wave radar and seismometers to improve the detection and the estimation of the wave parameters before its impact.
