This paper studies the impact of the M_W 9.0 Tohokuoki earthquake, March 11,2011, Japan on the crustal deformation, active fault movement and earthquake risk in the northeastern China by using continuous GPS data. The result shows that the direction and amount of principal strain is different between coseismic and interseismic strain field. In one word, the crustal strain accumulation and stress level of northeastern region in China is released by Tohokuoki earthquake, so the authors believe that the earthquake risk is reduced to a certain extent.
