摘要
Abstract
The isoline map of the heat flow has been drawn by using the measured and estimated values of the heat flow in Yunnan Province and its adjacent region. The contrast studies of the heat flow and epicenters of the strong earthquakes (886 ～ 1998), the distribution of the geotemperature and high accurate data of focal depth (1983 ～ 1997 ) show that the strong earthquakes take place along the geothermal gradient zone in which the thermal stress is concentrated, and that the foci are generally located between 100°and 600° isogeotherms corresponding to the depths of 3～ 25km and densely distribute between 200° and 450° isogeotherms, i.e. the depths of 5 ～20km. The distribution range of the focal depths is probably related to the crustal brittle to ductile transition which mainly results from the geotemperatures.关键词
