Based on hypothesis of seismo-geothermics and geotectonic data in Western China, we discuss the seis- motectonic activity pattern and seismic activity features of the Qinghai-Tibet Plateau, and pointed out that the Hingdu Kush and Myanmar seismic cylinders are the main reason of controlling the tectonic movement and seis- mic activity of Qinghai-Tibet Plateau, and the thick crust with 70 km in Tibetan Plateau is the favorable structur- al condition to induce within-crust strong earthquakes occurred frequently in inland regions. Then referring to his- torical earthquake case, we use activity dynamic of earthquake occurred in the lower crust with below 35 km in Tibetan Plateau and its surrounding areas. It could provide precursory indicators of possible activity intensity, activity locations and generally activity periods etc. for the within-crust strong earthquake activities and volcano activities in study area, and achieved primary effect. The seismotectonic activity pattern of Tibetan Plateau ex- plained by the seismic cylinder theory seems closer to the seismic activity characteristics of Tibetan plateau. It not only can be more reasonable to explain the cause of within-crust earthquake or volcano occurrence, but also can predict activity trend of the cylinders and its influence area in the next few years.
