DEFORMATION ANOMALY ANALYSIS AT HUZHOU SEISMOSTATION
BEFORE M 4.9 GAOYOU-BAOYING EARTHQUAKE
1)Huzhou Seismostation ,Earthquake Administration of Zhejiang Province, Huzhou 313000
Abstract The significant abnormal trends of deformation observations were found at the Huzhou seismostation before the M4.9 GaoyouBaoying earthquake. By combining the deformation data with the focal mechanism solution, the results show that the direction of the anomaly is consistent with the direction of background stress field of this area. The observed deformation anomalies are likely to reflect the changes in tectonic stress field.
