Theoretical S-P delays (in seconds, colorscale) for the station LAMJ (Lamjung) according to event epicentral distance and depth, estimated from the Pandey velocity model (a), with a systematic increase of 10% of the P & S wave velocities (b), with a systematic decrease of 10% of the P & S wave velocities (c) and with a systematic decrease of 10% of the velocities and a decrease of the VP/VS ratio from 1.75 (Pandey) to 1.70 (d). Colored dots are estimated event depths and epicentral distances to LAMJ; the color of the dots scale the S-P delays (in seconds) measured by analysts on LAMJ. Red dots show the depths that better fit these measured S-P delays, for the event epicentral distances and for each of the velocity model (a–d)
