Gravity Anomaly Detected by GOCE in China’s Western Region

Article Preview

Abstract:

In this paper, gravity anomaly in China’s western region is computed using GOCE data and GRACE data respectively. The result shows the gravity anomaly computing by GOCE data can reflect the spatial distribution characteristics of regional tectonics and seismic activity. This new technology provides a new observed method to study seismic activity. The spatial resolution of GOCE is more higher than GRACE.
