Shear Velocity Structure in NE China and Characterization of Infrasound Wave Propagation in the 1-210 Kilometer Range
Abstract
We continued the operation of the Southern Methodist University-Institute of Geophysics, China Earthquake Administration (SMU-IGPCEA) broadband seismic network through May 2008 using Program for the Array Seismic Studies of the Continental Lithosphere (PASSCAL) instrumentation. The operating network included three stations northwest of Beijing and 10 stations in Xiuyan. Lisoning Province, NE China. At the end of May, the PASSCAL instrumentation was returned to the U.S. During the 5.5-year operation, we collected approximately 600 Gb of miniSEED data. Most of the data have been archived at the Incorporated Research Institutes for Seismology (IRIS) data center. This high-quality dataset has already provided us the opportunity to study the detailed velocity structure beneath the Huailai Basin and Haicheng in NE China using both teleseismic and regional signals. We are expanding our joint inversion of teleseismic receiver functions and surface wave phase velocities for crustal shear velocity structure from the Huailai Basin to the Huabei area using data from SMU-IGPCEA broadband seismic network with additional data provided by 48 broadband seismic stations in this region.
