Short summary
Short summary
By testing the strength of granite in compression and tension at a range of deformation rates, we found that the strength increases with faster deformation. This observation highlights that at these rates, relevant for example to geothermal exploration, we have to consider how the rate of deformation impacts the energy released when rocks crack. The results are promising for developing safe procedures for extracting resources from the subsurface.

Short summary
Volcanic eruptions are controlled by the presence of gas bubbles in magma, which, in excess, can cause explosions. Eruption models lack an understanding of how gas percolates in magma flowing in a conduit. Here we study gas percolation in magma associated with the 1994–1995 eruption at Mt. Unzen, Japan. The results show that the pathways for gas escape depend on the depth and ascent rate of magma. Pathways closed at depth but opened along fractures when magma ascended rapidly near the surface.
