Extreme waves pose a significant threat to coastal areas and the communities residing there, with potentially devastating global impacts. This session will explore extreme wave phenomena, focusing on two of the most relevant: tsunamis, high-energy seismic waves generated by underwater earthquakes, volcanic eruptions, or landslides, and medicanes (Mediterranean Hurricanes), tropical-like cyclones forming in the Mediterranean, increasingly frequent and intense due to climate change. Through the analysis of recent scientific studies, predictive models, remote sensing data, and case studies of past events, speakers will provide an overview of the formation mechanisms of these phenomena, monitoring methodologies, and risk mitigation strategies for coastal populations. Furthermore, artificial intelligence and deep learning methods may represent an important topic to address for coastal monitoring. A combined use of these techniques allows obtaining an exhaustive framework for the geomorphological evidence related to extreme waves. The session will also cover the impact of extreme waves on marine ecosystems and infrastructure. The goal is to promote greater awareness and resilience in the face of extreme events within the context of ongoing climate and geological changes.
