Understanding the physical mechanisms of rock and exploring the characteristics of seismicity have attracted worldwide attention in solid earth geophysics. In the past, a great number of compression and shear experiments involving acoustic emission measurements have been carried out in an attempt to explain the underlying mechanisms of rocks for various geological phenomena. However, physics and seismicity of rocks are still faced with ever-increasing difficulties.

The surging demand for space and resources urges more efficient exploiting methods for deep mineral resources and low-carbon resources. Deep mining and tunneling may trigger dynamic disasters such as large-scale collapses and seismicity, leading to serious casualties and economic losses. The origin and slip mechanism of natural as well as induced earthquakes have not been well understood. Anthropogenic activities such as well drilling, water injection and the development of deep underground space become direct sources to frequent seismic activities.

It is extremely important to prevent the occurrence of disasters or minimize the risk and loss of accidents. As such, it is essential to extract useful knowledge from the data collected in both experiments and site practices by means of innovative experimental techniques, simulation methods, data mining, and geophysical methods. Efforts in integrating these technological means will help explore the challenging issues in rock physics and bring new breakthroughs of seismicity-related research.
