Abstract: The shallow layer geotemperature refers to geotemperature from ground surface to the depth of 3.2m.Through studies of the relationvship between the shallow layer geotemperature variations in the past several decades of years and strong earthquake activity,it has been pointed out that the correlation coefficient of geotemperature at depth of 0.8m and the ground vsurface temperature in a certain time interval before occurrence of strong earthquakes is the lowest value in the same period over the years;the geotemperatures at depth of 0.8m, 1.6m and 3.2m consecutively lasting more than six months are regarded as positive distance averages, and if the mean distance averages are larger than 0.8,0.7 and 0.5 respectively, it is considered that the geotemperatures show temperature-rising anomalies;in this time interval, geotemperature shows largest or second largest value in the same period over the years;plotting half year or monthly isoline nap of mean distance averages of geotemperature at depth of 0.8m and ground surface temperature, with isoline encircling the relative temperature-rising center, the temperature-rising area or its vicinity could be considered as the epicentral area of coming strong earthquakes.A detailed analysis of geotemperature anomalous variations associated with the Xingtai earthquake occurred in March of 1966, Tangvshan earthquake in July of 1976, Datong earthquake in October of 1989 has been made,the mechanism of anomalous temperature rising has been studied.and meanwhile the effect of rainfall on shallow layer geotemperature has also been analyzed.
