As part of the Memorandum of Understanding (MoU) signed between the National Institute of Geophysics and Volcanology and the Earth Sciences NZ (ESNZ, previously GNS) and more generally in the context of collaborations between the various global warning systems coordinated by the IOC-UNESCO, Yi-Wun Mika Liao, researcher at ESNZ,and University of Canterbury and Sean R. Santellanes researcher at University of Otago e ESNZ - who are visiting the INGV during the last ten days of September - are collaborating with the INGV Tsunami Alert Centre and with Malaga University to test PTF* in the southwestern Pacific and to integrate theTsunami-HySEA** model in the New Zealand's monitoring system.
The results will contribute to achieving the benchmarks set by UNESCO.
*PTF is an innovative method recently introduced by INGV researchers in collaboration with several other research institutions and universities for rapidly estimating the impact of tsunamis by quantifying the uncertainties of the estimates.
**Tsunami-HySEA belongs to the HySEA family of models and is specifically designed to reproduce tsunamis generated by seismic events. Its high computing power allows for simulations that are as reliable and accurate as possible, capable of accurately characterizing tsunami propagation faster than the actual phenomenon.
