![]() This provides a unique platform for the scientific community to explore the driving mechanisms of flood risk and to build up efficient strategies for flood mitigation and enhancing flood resilience. Combined with fit-for-purpose hydrodynamic/hydrological models, these techniques pave the way for breakthroughs in flood assessment and flood risk management. New and rapidly developing techniques are becoming widespread, such as UAV (unmanned aerial vehicle), ML(Machine Learning) or satellite-based systems (e.g., SAR, Altimeter, SCATSAT-1, etc.). It hampers well-being and economic growth in many countries, so that flood forecasting and flood risk assessment & management have become of upmost importance. ![]() Worldwide, the frequency and magnitude of extreme floods are steadily increasing, causing large scale flooding, accompanied by great economic/human losses, in inundation-prone areas of the world. This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. ![]() Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere for the atmospheric pressure wave generated by the explosion, which was detected globally and for generating a tsunami that was observable across Pacific Ocean shorelines. The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. ![]()
