ODTP Registration ITS2025 : Deadline for Submission of Abstracts Special Session on Kamchatka Tsunami and South Alaska landslide Tsunami upto 01 September 2025 | ODTP Registration Registration for ODTP Conference & ITS-2025 is open Now

Background

The 32nd 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

Themes

The increasing complexity and frequency of tsunami-related hazards in both seismic and non-seismic contexts demand a renewed scientific focus, multi-sectoral collaboration, and global cooperation. The International Tsunami Symposium brings together leading experts, practitioners, and stakeholders to address the full spectrum of tsunami science, risk reduction, and resilience-building. The following thematic areas have been thoughtfully selected to reflect the multidisciplinary nature of tsunami research and the evolving challenges in warning and mitigation:

  • Tsunami hazard, vulnerability and risk assessment
  • Paleotsunami Studies
  • Instrumentation and observation network
  • Tsunamigenic earthquake source mechanisms
  • Non-seismic and Complex tsunami Research
  • Tsunami modelling (seismic and non-seismic sources)
  • Experimental studies
  • Advanced Techniques (Real-time inundation modelling, use of high-performance computing, AI/ML etc.)
  • Field Surveys
  • Tsunami Data Analysis
  • Meteotsunamis including 2022 Tonga event
  • Communicating Uncertainties
  • Tsunami Awareness and Preparedness
  • Societal Dimensions of Tsunami Risk
  • International Cooperation and Private Partnerships
  • Special Session on Kamchatka Tsunami and South Alaska landslide Tsunami
