The paper analyzed and outlined the geothermal anomaly change of the 2 earthquakes of Xingtai andTangshan, and discussed the feasibility of the geothermal anomaly to make earthquake prediction.
The characters of the abrupt geothermal anomaly concern many factors such as geological structure, cause of volcanic formation, volcanic scope and type.
火山区的突发性地热异常特征与火山区的地质构造、火山成因、规模、类型等多种因素有关。
The shallow geothermal anomaly is discussed in combination with calculated results, and the problems to which attention should be paid in data interpretation are proposed.
