摘要： 以山西地震带热水点为基础资料,计算每个热水点的年热释放量,分析山西地区热水点的年热释放量与地震活动的关系。结果表明,热释放量低值区中小地震不活跃而强震活跃,高值区强震不活跃,而中小地震活跃。通过研究,还表明山西地区地壳活动所积累的能量,每年以热能形式释放的能量相当于一个7. 3级地震,这对强震的孕育起到了缓解的作用,因此可能推迟或减少地震的发生。

Abstract: Basedon the data of hydrothermal spots along the Shanxi seismic belt, the heat annually released at each spot is calculated. The relation between the heat annually released at hydrothermal spots and seismic activity in Shanxi region is analyzed. The re-sult shows that in the region where the lower the heatreleased, the more frequently the large earthquakes occur, but the more rarely the moderate and small earthquakes appear. On the other h and, the medium and small earthquakes occur frequently in the region where the heatreleased higher, and large earthquakes appearrarely. The re searchalso shows that the energy, accumulated by crustal activity in Shanxi region and released an nu-ally in the form of heat is equal to the energy released by an earthquake with M7. 3. It weakens the seismogenic process of strong earthquakes and breaks free from the recur-rence interval of strong earthquakes.
