Аннотация:Kamchatka Peninsula is famous for its widespread volcano groups. Typical hazards related to active volcanoes,such as lava,pyroclastic flow and lahar are also common in this region and exhibit distinctive features in initiation,motion,grain fraction from rainfall-triggered debris flows in China. Field investigations of three active volcanoes
( Shiveluch,Klyuchevskoy,and Tolbachik) were carried by Sino - Russia scientists in August,2013. Based on the survey data and background conditions of lahars such as topographic,geologic and morphologic settings, the formation factors,grain fraction and deposition of lahars were examined roughly and compared with typical rainfall-triggered debris flows in China. The basic conclusions in this paper are useful for promoting the research on lahars,pyroclastic flows etc,in China.
