Icequake rupture suggests Antarctic ice stream beds may be stronger, yet more dynamic than previously assumed

Ice slip controls the flow of fast-flowing glaciers that contribute most to sea-level rise. The ice-bed interface shear stiffness partially regulates the shear strength, which dictates how fast ice can slip. Here we present the first measurements of slip-generated icequake rupture velocities at R...
