Figure 3: LPW curves and model fit.

(a) Average logarithm of the Pd versus PTW (LPW) curve for each analysed event. The y-axis represents the average logarithm of Pd, obtained by using all the available data at each time point, after correcting individual values for the distance effect (using equation 1). The insert box is a schematic representation of the piecewise linear fitting function. (b,c,d), Example of LPW curve for three representative events of magnitude M 4.7 (b), 6.7 (c) and 9 (d), respectively. In each panel, grey circles are the observed data with the associated ±1σ error bars (dashed lines). The solid line is the best fit function, obtained using the piecewise linear model and the dark squares mark T1 and T2 times of each event.
