[1] Aseismic deformation transients can emerge as a natural outcome of the rate and state friction processes revealed in laboratory fault-sliding experiments. When that constitutive formulation is applied to model subduction earthquake sequences, transients can arise spontaneously for certain effective stress ( s) variations with depth. We show that if interstitial fluids are present and pore p...

Understanding the controls for magma ascent and storage depth is important for volcanic hazard assessment. Regional differences in the depths of magma storage between volcanic arcs suggest that the settings of subduction zones and of overriding plates influence howmagma ascends through the crust. Here we use a compilation of data for 70 volcanoes in 15 volcanic regions to better understand the ...
