摘要
The editors wish to highlight the articles appearing in this issue.The first article,entitled“New physics of supersonic ruptures”by Boris G.Tarasov,concerns the development of a new theory on the potential occurrence of ruptures after deep underground earthquakes.Two other articles belong to our first special theme of“Disaster evolution in deep underground.”The final two articles introduce a nonlocal damage fracture phasefield model for rock‐like materials and the gas–liquid displacement in microcleats for mass transfer through gas‐or water‐driven displacement.These five papers indeed explore various aspects of deep underground science and engineering and constitute an integral component of deep underground fundamentals.
