| Abstract: | Introduction Many observation facts, rock-rupture experimental results, and theoretical research achievements proved that the sudden changes in ground deformation are the most possible earthquake short-term precursors. The observed sudden changes in deformation that related to the earthquake preparation are here called the precursory. The sudden change is mainly characterized by the highly changing velocity and greatly accumulated deformation amplitude. |
