China Seismological Reference Model (CSRM)


Resolutions on establishing the “China Seismological Reference Model”  (Adopted at the Working Group meeting on 29 June 2016)

The current station coverage in China is dense and has surpassed that of the United States in many regions, such as the North-South Seismic Zone and North China. Researchers in China have also gained a more systematic understanding of the crust and mantle structure. The working group believes that the time is ripe to build a seismological reference model in China.

The “China Seismological Reference Model” (CSRM) should include:

  1. Reference models of the crustal seismic structure of velocity, attenuation, anisotropy, and crustal thickness in China
  2. Reference models of the upper mantle seismic structure of velocity, attenuation, and anisotropy in China
  3. Reference models of the upper mantle discontinuities in China

The CSRM construction should not be a patchwork of various models. The reference model must be consistent with all types of the seismic data. Therefore, the final CSRM construction must be a top-down process by simultaneously integrating various types of seismic constraints. The CSRM also needs to be continuously updated with the availability of new seismic data and the development of new seismological methods. From these two considerations, the CSRM construction needs to accumulate and archive the original seismic data and various seismic constraints used to construct the model.

The CSRM Rules and Data Policies

The CSRM should be established by a construction group (different from the working group) formed by the following mechanisms:

Researchers who make significant contributions in the model construction will become members of the group; any researcher who provides original data or new methods to the model construction can become a member of the group on a voluntary basis.

Original data submitted to the CSRM Product Center will be managed according to the following rules:

  1. The data (three years after the project completion) will be shared with researchers in China.
  2. The use of the data will be limited to the individual research team; some original data may be subject to the confidentiality requirements.
  3. The user of the data shall discuss with the original data providers on how to share the research results from the use of the data, with the minimum requirement being a citation of the article on the original data. Possible co-authorship should be considered subject to the wishes of the original data providers.
