In our paper we present the results of seismotomographic inversion for the local seismological monitoring data obtained in the area of the Samoylov Island (Lena River delta) in 2019-2021. Tomographic velocity model was used for refining hypocenter locations of local earthquakes and for geological interpretation. The results are shown as maps of anomalies of seismic waves and Vp/Vs ratios for the 5 and 10 km depths. The velocity anomalies structure made it possible to interpret low Vp/Vs ratio as rocks related to the Siberian platform, and to compare between the boundary of the low Vp/Vs area and the trace of the known geological fault running along the Olenekskaya Channel.
