【摘要】 对云南腾冲火山区剧烈地热活动及伴随的泉水发浑变色等宏观现象进行了现场调查及分析。通过对水样、气样化学组分、水温变化、降雨、该地区水热爆炸记录及当地震例等资料进行对比分析,结果表明腾冲剧烈地热活动,以及伴随的水发浑变色、流量增大、水温升高和喷水等宏观现象是该区域断裂活动增强和地下幔源物质活动加剧,分析认为是地震活动性的宏观现象。更多还原

【Abstract】 In this paper,the field investigation and analysis are carried out on the violent geothermal activity of Tengchong volcanic area in Yunnan and the muddy color of the spring water. The water sample,gas sample chemical composition,water temperature change,rainfall,water thermal explosion in this area and earthquake cases are compared and analyzed. The results show that Tengchong violent geothermal activities,as well as the macroscopic phenomena become muddy color,the flow increases,water temperature and water spraying is enhanced and underground mantle activity increased the performance of fault activity in this area. It is a macroscopic anomaly of an earthquake and should be treated as an anomaly of earthquake precursors.更多还原
