Recent eruptions at Axial Volcano, West Mata Submarine Volcano, “Volcano F'' in the Tofua Arc, a new volcano off the eastern coast of Mayote and others have spurred interest in submarine volcanism. Submarine volcanoes have all the eruptive products of subaerial volcanoes (e.g., lava flows, explosions, ash/lapilli/pumice, cone growth) combined with extensive hydrothermal systems through which they influence ocean chemistry and sustain complex ecosystems. Interactions between the volcanic systems and the various tectonic/magmatic settings (including mid-oceanic spreading ridges, intraplate settings, and subduction zones) that host them produce a complex variety of response.

Recent advances in oceanographic data collection through the use of Remotely Operated and Autonomous Underwater Vehicles, along with seafloor geophysical instrumentation at cabled submarine observatories, have allowed monitoring of submarine volcanoes before, during, and after eruptions in unprecedented detail. This new detail is leading to greater understanding of past (ancient) deposits from submarine volcanoes, present hazards of such volcanism, and the processes driving submarine eruptions.

This Research Topic will explore the diversity of submarine volcanism, the hydrothermal systems that occur in connection with them, the biological ecosystems thriving there, and the tectonic systems that host them. Although open to scientists at any stage of their career, we encourage the submission of scientific contributions led by early career scientists.

We encourage papers covering both submarine volcanism proper and connected topics such as hydrothermal systems, related tectonics, and vent ecosystems. Specific topics could include but are not limited to:

• Eruption styles;
• Seismicity related to submarine volcanism;
• Hydrothermal systems;
• Tectonics and structural geology - driving forces, related fault dynamics, etc.;
• Vent ecosystems;
• Hazards resulting from submarine volcanism;
• Geochemistry and petrology of submarine magmatic systems.
