All China Seismic Structure Seismic Imaging Method
China Seismological Reference Model
Goal of this project are two folds: 1) constructing a reference seismic model of the crust and uppermost mantle beneath the continental China with multiple seismic constraints where a top-down construction regime is adopted, 2) understanding compositional and thermal states of bedrocks in the crust and uppermost mantle beneath continental China.

CSRM-1.0: A China Seismological Reference Model
CSRM-1.0: A China Seismological Reference Model

  1. CSRM-1.0 is constructed with various seismic constraints from data of 4435 stations using a self-consistent top-down construction process
  2. CSRM-1.0 improvements include accurate estimation of shallow seismic structure, increased spatial resolution, and enhanced model accuracy
  3. CSRM-1.0 reveals major crustal mafic rocks related to the past subductions, an Emeishan mantle plume and geological inter-block boundaries

Simultaneous inversion for surface wave phase velocity and earthquake centroid parameters: methodology and application
Simultaneous inversion for surface wave phase velocity and earthquake centroid parameters: methodology and application

  1. We develop and test a strategy of combining seismic ambient noise and regional earthquake surface wave data in constraining seismic structure of the Earth
  1. We provide high-resolution phase velocity maps and earthquake centroid parameters in the North South Seismic Belt region in the continental China and gain insights on evolutional histories of the region

Shallow seismic structure beneath China revealed by P wave polarization, Rayleigh wave ellipticity and receiver function
Shallow seismic structure beneath China revealed by P wave polarization, Rayleigh wave ellipticity and receiver function

  1. We develope a new method to constrain shallow seismic structure based on P polarization, Rayleigh wave ellipticity and receiver function.
  2. We construct a high-resolution shallow 3D seismic model in the top 10 km of the upper crust in the continental Cina.
  3. Our 3D seismic model has a spatial resolution of $0.6^°-1.2^°$ in the north-south seismic belt and the trans-north China orogen, and $1^°-2^°$ in the rest of the continental China (except the Tarim basin and the southwest Tibet).
