Probability density function of ascent velocity of the gas phase in the conduit. Probability density function of the ascent velocity of the gas phase (uasc) with different conditions of the VLP source depth [dVLP; 300 m (a, b), 400 m (c, d), and 500 m (e, f)] and the propagation velocity of the VLP signal [vsL; 2700 m/s (a, c, e) and 1585 m/s (b, d, f)]. The meaning of the black lines in all the diagrams is the same as in Fig. 6
