Abstract Crustal deformation is the most direct phenomenon of the earthquake preparation, occurrence and adjustment process. This paper briefly reviews the development history of the crustal deformation observation, summarizes the development set up of its related physical model about earthquake forecast, and then introduces the current application of the deformation data in the earthquake domain. In the future, we suggest to pay more attentions to two aspects: 1) in geodesy surveying domain, we should dense observations in typical tectonic zones first, and then construct the universal geodetic model with multi-source data; 2) in research domain, we should develop the methods to obtain the stress/strain field in high-resolution, construct the relationship between the stress/strain field and the earthquake process, study and obtain the crustal viscosity structure distribution in high accuracy, strengthen to research the deformation mechanism of the active tectonic block, promote study of the reliable method and model to invert fault slip rate, locking degree, and slip deficit distribution, and strengthen recognition of the pattern and mechanism of abnormity phenomena in the continuous observation for typical areas. In general, the core issue is to provide effective observational constraints and establish quantitative mechanical models for the fault deformation mechanism, which is the key to understanding the earthquake process and promoting the physical forecast of strong earthquakes.
