The extension in continental rifts is accommodated by dike intrusions, faulting or both depending on the maturity of the rift system. Early stage rifting is mostly dominated by fault processes whereas advanced rifts are mostly dominated by magmatic processes. Magmatic processes such as dike intrusions occur associated with elevated seismicity with/without measurable surface deformation. The time-scale of the seismicity and surface deformation can show nature and depth of a magma plumbing system. Magmatic intrusions typically last from few hours to few days. Studying the co-and post-intrusion time history of deformation could reveal the rheology and magma dynamics of the system. The Main Ethiopian Rift (MER) provides a good opportunity to observe interaction between magmatic intrusions, fault systems and volcanic centres.
