Abstract: Many significant progresses were obtained on the physical processes of volcanic activities in the Quaternary volcanic area in China during the past few years.The physical processes of solidification,fractional crystallization and stability of magma chambers,the dynamics of volcanic conduits and eruption columns,and the transport and emplacement of pyroclasts and lava flows are addressed and reviewed.The fractal characteristics of pyroclasts and lava flows and the nonlinear processes existing in the dynamic system of magma chambers are commented,especially.

Key words: magma chamber; volcanic conduit; eruption column; emplacement processes; physical mechanism; nonlinear processes
