Suggestions and criteria to our presentations are briefly summarized. Associated with these international meetings, Japan-China cooperative seismo-geothermal excursion to the Sichuan and the Guangdong Provinces were made. The occurrence of large earthquakes in the Sichuan Plateau well coincides with the distribution of large active faults, along which warm to high temperature thermal springs issue. Considerable anomalies require for the prediction of earthquake have been observed at these thermal springs. The aerial distribution of hot springs in the southern China is considerably large by 1200×400km, which is larger than the area of Honshu Island, Japan. There is possibility the existence of the Quaternary monogenetic volcanoes associated with active faults in the southern China provinces. The volcanic edifice of Xiqiao (344m) standing on the Pearl river delta plain dated as 50 Ma by K-Ar method must be a Quaternary volcano, but not be as such old volcano. Geomorphological impression of this volcano should be at an age of 0.5 Ma. The distribution of hot springs and of the Quaternary volcanoes may suggest the presence of tensional stress field in this area. A careful reexamination of future destructive earthquakes might be required in this area.}, pages = {1--17}, title = {1996 IASPEI・第30回万国地質学会および四川省・広東省の地震と地熱活動の日中共同研究現地検討会}, volume = {18}, year = {1997} }
