Dear coastal_listers

We are pleased to make an announcement of the Coastal Hazards session in AOGS2026

which will be held from 02 August to 07 August, 2026, in Fukuoka, Japan. 

It's time to advertise the AOGS session, as the submission deadline (23 Jan, 2026) is approaching.

OS11 Coastal Hazards: Impacts of Tropical Storms and Tsunamis

Main Convener:	Prof Nobuhito Mori (Kyoto University, Japan)
Co-convener(s)	Prof Linlin Li (Sun Yat-Sen University, China)   Prof Philip L.-F. Liu (Texas A&M University, Cornell University, US)  Prof Sungwon Shin (Hanyang University, Korea, South)  Prof Xiping Yu (Southern University of Science and Technology, China)

Session Description: 

Coastal hazards, including tropical storms and tsunamis, are among the deadliest natural hazards in human history, collectively likely responsible for more deaths and economic losses with a changing climate and rapid coastal development. This session will discuss the impacts of two major coastal hazards: tropical cyclone-induced coastal flooding and tsunamis from their source mechanism, wave characteristics, and coastal morphological change. Both storms and tsunamis commonly lead to varying degrees of coastal flooding, coastal erosion, human and economic loss, although they do have different causes. To better understand and prepare for such coastal hazards in a changing environment, we propose this session which covers the following topics: (1) Characteristics of historical and recent storm surge and tsunami events; (2) hydrodynamics (ocean wave, tide, and surge) of coastal flooding considering multiple physical processes associated with typhoon: extreme rainfall, wind and storm surge; (3) hydrodynamics of tsunami waves considering different source mechanism, e.g. earthquakes, submarine landslides, volcanic eruptions, etc; 4) characteristics of sediment transport during storm surge and tsunami; 5) storm surge and tsunami hazard assessment; 6) the potential impact of climate change (sea level rise, storm climatology) on the coastal flooding hazard. In response to extremely damaging typhoon events (e.g., the 2024 super typhoon Gaemi, the 2024 super typhoon Yagi, the 2024 Typhoon Bebinca, the 2025 Super Typhoon Ragasa) in recent years, we continue to organize the sub-session dedicated to understanding the physical processes of these extreme typhoons and their hazard impacts. These extreme events demonstrate that a single extreme typhoon could cause severe damage in several countries/regions along its track; a holistic investigation approach is required to comprehend the entire lifespan of a typhoon and its hazard mechanisms. Through this initiative, we hope to promote concrete collaborations among researchers in the Asia and Oceania regions to better understand the typhoon-induced hazards.

Thank you very much and happy 2026!
