1970年以来青藏高原破坏性地震目录

青藏高原地区地震活动强烈，其地震活动的动力来源于印度板块与欧亚板块的俯冲碰撞及高原内部变形。本数据集包含在青藏高原及周边区（北纬20-40度，东经70-105度）1970年以来发生的2854次M≥4.7级地震的震中位置、发震时刻、地震震级等信息，其中M≥8级地震3次，M=7.0-7.9级地震33次， M=6.0-6.9级地震192次， M=5.0-5.9级地震1152次。地震主要沿青藏高原周边及高原内部的大型断裂带发生。

The Tibetan Plateau region features intense seismic activity, which is driven by the subduction and collision between the Indian Plate and the Eurasian Plate, as well as the internal deformation of the plateau. This dataset contains information such as epicenter locations, origin times and seismic magnitudes of 2854 earthquakes with M≥4.7 that occurred since 1970 in the Tibetan Plateau and its surrounding areas (20°N–40°N, 70°E–105°E). Among these events, there are 3 earthquakes with M≥8, 33 earthquakes with magnitude 7.0–7.9, 192 earthquakes with magnitude 6.0–6.9, and 1152 earthquakes with magnitude 5.0–5.9. Most of these earthquakes occur along the major fault zones around the Tibetan Plateau and within the plateau itself.
