"Bang, Fizzle, Pop: Case studies of the interactions between volcanoes and magma with the ocean"
Volcanic eruptions are fascinating for scientists and the public alike. Visual observations of eruption on land have been central to the scientific understanding and development of various models used in hazard forecasting. However, in a submarine setting the interaction between hot magma and seawater is hidden and therefore is not well understood. Recent submarine eruptions like the Hunga Tonga eruption in 2022 are extraordinary and can be devastating. International scientific teams with innovative robotic technologies have responded to these events to characterise and further understand submarine eruptions. These well characterised events underpin step changes in our understanding of how magmas and volcanoes interact with the ocean. In this presentation, I will describe case studies of recent submarine eruptions and underwater exploration of the eruption products to highlight advances and remaining challenges in the study of underwater volcanoes.
