ADRC Online Tsunami Seminar

Although the understanding of tsunami risk has improved, further discussions are still needed in enhancing practical countermeasures.

• While tsunami occurrence is rare, it is deadlier and costlier compared with other hazards. For instance, the economic impact of the Great East Japan Earthquake and Tsunami alone costs about USD235 billion the highest in world history.
• Non-earthquake sources of tsunami (e.g., the Sunda Strait Tsunami of 2018 and the Tonga Volcanic Eruption and Tsunami of 2022) are still less understood. Hence, early warning systems and preparedness measures are not yet fully developed nor standardized.
• New tsunami countermeasures that protect critical infrastructures (e.g., undersea cable networks) need to be developed to avoid a repeat of massive network disruptions that occurred during the 2022 Tonga Volcanic Eruption.

Against this backdrop, the discussions in the Tsunami Seminar 2022 will take a deep dive on the practical countermeasures for tsunami risk (e.g., greater awareness, deeper understanding, and simple evacuation procedures).

Speakers of the tsunami seminar will share knowledge and experience on tsunami disaster risk reduction (DRR) efforts to draw insights on:

• Improving the understanding and address common misconceptions about tsunami risk
• Enhancing practical countermeasures for tsunami, particularly in terms of community preparedness and risk communication
