Abstract
The first results of microseismic sounding the deep structure of the Earth's crust in the western part of the Middle Amur sedimentary basin are presented. Based on the measurement data at 70 points, we produced sections of the relative velocities of S waves along two transversely crossing profiles, total length 90 km. The profiles cross the Itun-Yilan fault zone and other large regional faults zones as well as the Bashmaksky, Preobrazhenovsky, and Samaro-Ditursky grabens. The sections at depths of 4-10 km do not contain velocity anomalies. This may explain the lower seismicity of the studied zone compared to neighboring areas of the Tan Lu fault system.
