This video illustrates the topography, geology and results of a NERC research programme being conducted in the Afar Depression in north-eastern Ethiopia.

Our work here is to understand the interaction of magmatism and tectonism in the splitting apart of the Earth's crust to form a new ocean.

The video fly-through has been compiled within GeoVisionary software at BGS and shows satellite images of the ground surface before looking at the sub-surface location of earthquakes (shown as they occur through time in three-month-long periods), interpretations of magnetotelluric data (MT) to show the areas of the crust that are molten magma (hot colours), the position of magma chambers and a dyke modelled from these data to feed magma from lower in the crust to the surface, causing volcanic eruptions.
