Rifting incorporates the fundamental processes concerning the breakup of continental lithosphere and plays a significant role in the formation and evolution of sedimentary basins. In spite of numerous geoscientific studies, the mechanisms responsible for the initiation and development of continental rifts are still poorly understood. In order to decipher the characteristics of rifting at its earliest stage, 50 PASSCAL broadband seismic stations were installed for the SAFARI (Seismic Arrays For African Rift Initiation) experiment from 2012 to 2014 across the Malawi (MRZ), Luangwa (LRZ), and Okavango (ORZ) rift zones (Fig. 1). The studies summarized herein represent the first local teleseismic investigations to examine crustal/mantle structure and anisotropy using a dense array among any of the three rift zones.
