英文摘要The vertical component of continuous data recorded by the temporary NECsaids array and regional permanent broadband seismic stations from July 2010 to December 2014 in the deep subduction zone in northeast China are used to obtain the Rayleigh wave phase velocity maps at periods 6 similar to 40 s in the study area, then the Rayleigh wave phase velocity dispersions are inverted to determine 1-D shear wave velocity and assembled into a 3-D model of depth 0 similar to 50 km. The results show that the S wave velocity structure of the crust has lateral and vertical heterogeneity, the velocity structure of shallow crust is well related with the tectonic units on the surface, and the deep structure reveals the volcanism and regional deep thermal erosion effect. The low velocity anomaly bodies are found at depth of 9 similar to 30 km beneath the Changbaishan volcano and have a tendency to extend deeper, which may be the magma chamber in crust of the Changbaishan volcano. There is also a weak low velocity anomaly body at depth of 12 similar to 30 km beneath the Longgang volcano, which may be the remains after eruption, and no obvious low velocity anomaly body beneath the Jingpohu volcano, which means that there is no partial melting magma in the crust below it.
