From: Tremor signals reveal the structure and dynamics of the Oldoinyo Lengai magmatic plumbing system
a Tectonic setting and geophysical network of the SEISVOL project. Red triangles are station locations, dashed lines indicate major faults, yellow lines depict dike intrusions in 2007. Inset shows research area within the EARS. b Schematic of Oldoinyo Lengai’s plumbing system altered from ref. 11, using results by Reiss et al.12,18 for the melt reservoir at the top of Oldoinyo Lengai and Petibon et al.72 for the melt reservoir at the foot of the volcano. NBF and GF are the Natron Border Fault and Gelai Fault.
