Short summary
Here, we use tomography to reconstructed the pores of erupted pumice and understand the evolution of gas bubbles in magma. Analysis of the pore geometry is used to describe whether the pores where aligned by stretching as ascending magma is pulled apart (pure shear) or sheared like a deck of card (simple shear). We conclude that the latter, simple shear, dominates during magma ascent up to the points where magma fragments to cause an explosion.
Here, we use tomography to reconstructed the pores of erupted pumice and understand the...
