Going round the twist: The effect of stress on magma intrusion in Scotland and the Canary Islands

Introduction. Magma is transported through the crust in fractures called dykes that cut across rock layers. Dykes are important in all stages in the life of a volcano; they transport magma from depth but may stall during ascent or reach the surface to feed eruptions (see Kavanagh 2018 for a review).
How do aeolian avalanche dynamics control desert dune migration?

Desert barchan and transverse dunes typically migrate by avalanching. However, work investigating avalanche dynamics has previously been hampered because the lee slopes on which avalanches occur are typically at the angle of repose and unstable for mounting instruments.
