The influence of magma plumbing complexity on monogenetic eruptions, Jeju Island, Korea

Research on Jeju Island's monogenetic volcanoes reveals that single eruptions can involve multiple distinct magma pulses, which may erupt sequentially or independently. This complexity arises from the island's magma plumbing system—clear systems lead to uninterrupted eruptions with continuous chemical trends in deposits, while congested dyke complexes cause vent shifts and mixed chemical patterns. By analyzing pyroclastic successions and geochemical data, scientists demonstrate that eruptive dynamics and chemical variation are linked, providing new insights into monogenetic volcano behavior.
