Abstract: In this paper an analysis of many data of temperature on ground surface suggests that the suddenly increasing abnormal temperature on ground surface in seismic area is a kind of imminent earthquake precursor,which was found before two Lancang-Gengma earthquakes on Nov. 6,1988. Here we discuss the relationship between the regularities of the increasing temperature in time and space and earthquake activity,and the mechanism of the in creasing temperature on ground surface.

Key words: Imminent earthquake precursor, Increasing temperature on ground surface, Lancang-Gengma earthquaake

摘要： 本文通过较多的地面温度资料分析,认为1988年11月6日澜沧、耿马地震前几天,震区及其周围大范围的突发性地面增温异常是一种临震前兆,总结了增温异常的时空演变规律与地震活动的关系,并对其形成机制提出初步想法。
