International Tsunami Symposium 2025

Background

The 32^nd International Tsunami symposium would be coming up in the month of November 2025 for three consecutive days. The primary goal of this symposium is to develop and implement a robust program that upholds professional excellence among participants specializing in diverse, dynamic fields such as tsunami hazard assessment, detection, monitoring, early warning systems, mitigation strategies and community preparedness. Throughout this major annual event, attendees will engage in peer-reviewed and technical sessions designed to explore and address the latest advancements and developments within these crucial areas.

In 2022, A volcanic eruption in Tonga surprised scientists by triggering two types of tsunamis: "classic" tsunamis caused by the displacement of large volumes of water, and meteotsunamis caused by fast-moving pressure disturbances in the atmosphere. The classic example of non-seismic tsunamis. Read More

Objectives

To report on and document the achievements in Tsunami Science
To identify the challenges and gaps in the early warning system and work that still needs to be done
To enhance interdisciplinary collaboration especially for non-seismic tsunami source detection and tsunami forecasting
To enhance tsunami detection and warning systems through the latest technological advancements like high-performance computing and AI/ML
To promote global tsunami preparedness through UNESCO-IOC Tsunami Ready Recognition Programme and similar programmes/projects
To leverage on the Ocean Decade Tsunami Programme for improvement
