ISOSTATIC GRAVITY ANOMALIES OF BADONG REGION AND
TECTONIC ACTIVITY
1)Key Laboratory of Computional Geodynamics,CAS，Beijing 100049
Abstract Isostatic gravity anomaly in Badong area was calculated using the Airy model.The results show that the isostatic gravity anomaly ranged from -45×10-5ms-2 to 45×10-5ms-2，the most of the region was in the gravity isostatic state.Weak positive anomaly and weak negative anomaly appeaed in local areas，and weak positive isostatic anomaly presents in strip.The study shows that Taihang，Wuling gravity zone basically was in isostatic state with some differences in the internal.The northwestern in Badong area might occur isostatic adjustment.Badong Earthquake region was in the gravity isostatic state，that means the Badong Earthquake does not relate to the isostatic adjustment.
Key words ：
Badong area
earthquake
