New type of volcanic eruption


Unique to underwater volcanoes, neither effusive nor explosive



Scientists based in the UK and New Zealand have described a “new” type of volcanic eruption.

Volcanic eruptions are commonly categorised as either explosive or effusive. But now, in research published this month in Nature Geoscience, researchers at Victoria University, Wellington and the National Oceanography Centre in Southampton have uncovered a previously undocumented type of eruption in underwater volcanoes – by looking at tiny original bubble spaces trapped in volcanic rock.

Inside volcanoes, gases are dissolved in the molten magma as a function of the very high pressures and chemistry of the magma. In the same way that gases dissolved in carbonated drinks bubble up when you take the lid off, when magma is erupted as lava, the pressure is relieved and the gases exsolve to form small gas bubbles or so-called “vesicles”. In explosive eruptions these vesicles expand so quickly they fragment the magma, violently ejecting lava, which cools and degasses to form solidified pumice that can be sufficiently light to float on water....
