Abstract

Tsunamis, often linked to seismic events such as earthquakes, can also be triggered by volcanic eruptions, posing significant risks to coastal regions. This paper investigates the tsunami generated by the volcanic eruption in the Tonga
Islands on January 15, 2022, focusing on the behaviour of overtopping tsunami waves and their interaction with coastal structures. The study utilizes video footage and data from social media, supplemented by location information from
Google Maps, to establish the affected coastal area's characteristics. Accurate data on the shape and dimensions of nearby barriers was crucial for effective numerical modelling, which was carried out using DualSPHysics software. The
numerical modelling results provide insights into offshore water surface elevation, wave velocity, bore impact forces, and pressure distribution on vertical barriers. These findings offer a preliminary approach to understanding the
interaction between volcanic-induced tsunamis and coastal infrastructure, contributing to the development of effective mitigation strategies for enhancing community resilience to such events.
