摘要
The great Haiyuan earthquake occurred in the southern Ningxia Autonomous Region. The magnitude of this earthquake is 8.5. Study on this earthquake using modern scientific and technological methods is the first in the history of earthquake research in China. Quantitative studies were carried out on fine structures and geometry of the fault zone, Holocene slip rate, co-seismic displacement, paleoearthquake and recurrence interval of great earthquake, and future earthquake risk assessment. The innovative studies also include rupture propagation along strike-slip fault, evolution of pull-apart basin, determination of total offset across the strike-slip fault, transition equilibrium between strike-slip displacement along its major strand and crustal shortening at its end of the strike-slip fault, and the mechanism of deformation on the Liupanshan Mountains.
