THE TECTONIC FEATURE OF REPEATED ANOMALY IN SANMAFANG WATER TEMPERATURE

The anomaly of Sanmafang water temperature is correspondent with some earthquakes, and its shape of anomalies is repetitive and alike. As the shape of anomaly for the earthquake occurred in Zhangjiakou-Bohai Sea seismic zone is dropping type, and rising type for the earthquakes occurred in Yinshan-Yanshan seismic zone, it shows that the character of anomaly shape are controlled by active tectonics. It is significant to study the relationship between Sanmafang water temperature anomaly and the earthquakes in active tectonic zone.
