【Abstract】 The Observation and research on hot and warm spring of volcano are of great significance to monitoring the activity of dormant volcanoes and to the evaluation and prediction of the potential risk of volcanic eruption. Since 1985, detailed reconnaissance, observation, and research on the hot and warm springs in Changbaishan Tianchi volcano have been carried out by the Seismological Bureau of Yanbian Prefecture. The results of observation and research show that the temperature and gas content of the hot and warm springs in Changbaishan Tianchi volcanic area have rather obvious variation, indicating that the magma in deep part of this area is now being in its instability period. The hot and warm springs in Changbaishan Mountains are controlled by major fault zone. The related fault zones are the east-west-trending and nearly north-south-trending fault zones.更多还原
