Fig 7. Ranked earthquake magnitudes combining California data [23] for the two years 2015 and 2017 shown in blue.

Inset (a) data is fitted with a trajectory from Eq (3) with q = α = z = 1.9303 shown in red in logarithmic scales. Main panel: Magenta dashed-dotted curve shows a trajectory from Eq (3) with q = α = z = 2 and a small shift from tangency ϵ = 6.688 × 10⁻⁵ in semi-logarithmic scales. A vertical shift of a distance T = (ln N_max)/2 = 5.2959 results in the red curve that fits the data in blue quantitatively. Inset (b) Same as main panel but in logarithmic scales.
