Fig. 1. Travel time analysis.
a Travel times of the observed and calculated travel times of the P and S waves after source locations in the final 3D model versus hypocentral distances. b Wadati diagrams for the cases of experimental data (red dots) and travel times calculated in the final tomography model (blue dots). In both cases, the linear regression coefficients are equal to 1.71. c Wadati diagrams for the data constructed in two synthetic models with Vp/Vs equal to 2.0 (red dots) and 1.7 (blue dots). The regression coefficients are indicated with the corresponding colors.

Fig. 2. Examples of seismic records on the sea bottom and ice floe in two sites.
The upper traces with names starting with “GKD” correspond to an earthquake recorded by four ocean bottom seismometers at a volcano at 120°E Gakkel Ridge. The other traces with names starting with “G85” demonstrate an earthquake recorded at the 85°E volcano by seismometers on ice floes. For display, the amplitudes of station GKD04 were downscaled by a factor of 5 and for stations G8530-33 by a factor of 10 compared to the other records of the same earthquake. A bandpass filter of 3–15 Hz was applied to all traces. The approximate positions of the P and S phase arrivals are marked by blue and red triangles, respectively.
