The NEAM Tsunami Hazard Model 2018 (NEAMTHM18) is a probabilistic hazard model for tsunamis generated by earthquakes. It covers the coastlines of the North-East Atlantic, the Mediterranean, and connected Seas (NEAM).
The model is manufactured in three versions depending on materials used - GFC, CFC and Super Light. The latest Tsunami Super Light comprises a different technology and the use of new materials ensuring a big advantage of the extremely low all-up weight (from 1850 g).
26 wrz 2022 · The modelled air-wave travels at an approximated constant speed of 317 m/s with an amplitude that decays with distance from the volcano. We then simulated the generation and propagation of tsunami due to the propagating air-wave in the atmosphere above the ocean.
18 kwi 2024 · Tsunamis generated by the Hunga Tonga–Hunga Ha’apai volcanic eruption on January 15, 2022 were recorded on ocean bottom pressure and tide gauges around the Pacific Ocean, earlier than the expected arrival times calculated by tsunami propagation speed.
7 wrz 2022 · Tsunami propagation modeling. To obtain the tsunami propagation results for different explosion magnitudes, numerical tsunami modeling was run by the TUNAMI model, which was first developed...
25 sie 2023 · In this study, we conducted simulations of tsunamis on the Japanese coast caused by the 2022 Hunga Tonga-Hunga Ha’apai volcano eruption on the Japanese coast, where the tsunamis were significantly amplified in many areas by air pressure waves from the eruption.
15 sty 2022 · This air pressure wave is often referred to as the Lamb wave in the literature. The air pressure records are used to develop a simplified model describing the Lamb wave by a combination of two Gaussian functions propagating axis-symmetrically from the volcano location.
