A lab that reproduces volcanic eruption plumes using supercomputers and laboratory experiments.
AboutAbout the lab
Reproducing the behavior of eruption plumes on computers
The Suzuki Lab studies flows associated with volcanic eruptions, such as eruption plumes and pyroclastic flows.
An eruption plume is a flow of volcanic ash mixed with volcanic gas. Because it mixes with the surrounding atmosphere through turbulence, how it moves is still not well understood.
Using numerical simulations and laboratory experiments, the lab is attempting to directly reproduce full-scale eruption plumes on supercomputers.
While aiming for a fundamental understanding of these phenomena, the lab is also involved in disaster prevention projects to reduce volcanic hazards.
Key terms
- Eruption plume
- A cloud of volcanic ash mixed with volcanic gas that is ejected from the vent during an eruption
- Pyroclastic flow
- A phenomenon in which volcanic ash and rock fragments, together with hot gas, move as a single mass and rush down a volcano's slope at high speed
- Multiphase flow
- A flow in which materials with different properties, such as a gas and solid particles, are mixed together
- Large-scale parallel computing
- A method of running many of a supercomputer's processors at the same time, splitting a large calculation among them to solve it

ResearchResearch themes
A volcanic eruption is a dynamic phenomenon that spans the solid Earth, the atmosphere, and the oceans. Using numerical simulations and laboratory experiments as its methods, the lab aims to clarify the behavior of the fluids involved in eruptions.
*Illustrative imageReproducing eruption plumes at full scale
Does an eruption plume rise as a plume column or flow down as a pyroclastic flow? How high does it rise? Where does ash of each particle size settle, and how far does it spread? Eruption plumes are multiphase flows, which makes the problem difficult. The lab is attempting to directly reproduce full-scale eruption plumes using large-scale parallel computing on supercomputers.
*Illustrative imageExploring how the flows work through laboratory experiments
The flows in eruptions also involve fluid dynamics problems such as jets, plumes, and thermals. By examining flows under conditions that are as simple as possible in laboratory experiments, the lab aims to discover new scaling laws.
*Illustrative imageDisaster prevention research to reduce volcanic hazards
While aiming for a fundamental understanding of the phenomena, the lab carries out its research in close connection with disaster prevention projects aimed at mitigating volcanic hazards.
*Illustrative imageWater circulation inside the Sakurajima volcanic edifice
To clarify how water circulates inside a volcanic edifice, the lab conducts sampling surveys of groundwater and hot spring water at Sakurajima, jointly with a team from AIST.
