| Outline of Final Research Achievements |
Fluid experiments on buoyancy-driven flows in deformable gel beads layer were conducted to understand the dynamics of magma transport in a partially molten region. As an analogue material of partially molten media, a mixture of transparent hydro gel beads and viscous fluids was used. Our experimental results indicate that the intermittent nature of the volcanic activity is inherent to magma transport in a partially molten zone, which explains the spatio-temporal patterns of volcanic activity.
