Home Reef is an ephemeral volcanic island in the Tonga-Kermadec arc that emerges to the sea surface following repeated submarine eruptions. Documented eruptions in 1852, 1984, 2006, and most recently in 2022 have each created short-lived landmasses. The 2006 eruption was particularly spectacular, releasing huge amounts of pumice that drifted as rafts as far as the east coast of Australia. In September 2022, a new island grew to an area of several hectares within a few days. The geological structure of Home Reef is closely linked to the subduction of the Pacific Plate, which generates magma in this region. When no island is visible, the volcano's summit is at a depth of approximately 400 meters below sea level. Observing this reef provides valuable insights into the formation of new landmasses and the dynamics of submarine volcanic systems.
