Fig. 3: Tremor locations results.
From: Tremor signals reveal the structure and dynamics of the Oldoinyo Lengai magmatic plumbing system
Results are displayed by frequency between February 21st and April 9th 2020 for several narrow frequency bands shown as filled circles. The size of the symbol corresponds to the number of located tremors at this location (cyan for 1–1.6 Hz, dark purple for 1.4–2.4 Hz, berry for 2.2–4.4 Hz, orange for 4.4–5.5 Hz, dark blue for 7–8 Hz). Gray dots are earthquakes from ref. 37. The dashed gray lines indicate the cross sections for the topography in the right and lower subpanels. Dashed black lines are major faults. Brown solid lines are dike intrusion from 2007/08.
