摘要
Using velocity-field data observed by GPS from 1999 to 2009 in the Fen-Wei Fracture Belt, the authors study the features of the dynamic evolution of the cross-fracture section deformation, the difference of strain accumulation between fracture segments, and the possible influence of the MS8.0 Wenchuan Earthquake on the Belt. The result shows that in recent 10 years, the southern segment of the Shanxi fracture and the middle-eastern Weihe Basin displayed relatively faster strain-accumulation, the southern margin fault of the Weiguang Basin and the western segment of the Weihe fracture also existed strain accumulation to some extent.
