“The challenging part of studying the Tonga tsunami was to quantitatively explain all the observed tsunami features that were completely different from those of common tsunamis”, adds Rachid Omira, stating: “A fast-moving atmospheric wave able to excite the ocean surface and pump energy into it was our explanation for this tsunami that “jumped” from an ocean to another and reached the coast of Portugal 10 hours earlier than expected”. In their conclusions, the scientists provide an exact explanation for the tsunami that was witnessed around the world and make hazard-related recommendations. In this study, the research team looked at satellite, sea-level, and atmospheric data from all over the world and used numerical and analytical models to show that the tsunami was caused by an acoustic-gravity wave that was generated by the volcano explosion and that it traveled several times across the globe.
