云南是一个地震多发区。１６５２年至１９９４年间云南地区共发生６１３次破坏性地震，其中５．０—５．９级地震５５３次，６．０—６．９级地震４９次，７．０—７．９级地震１２次，８级地震１次。云南的破坏性地震除了直接造成人员伤亡和建（构）筑物破坏外，还在震区形成包括滚石、崩塌、滑坡、泥石流、地面沉陷和喷砂冒水等地面破坏现象，这些地面破坏造成人员伤亡，毁坏建筑物和农田，形成云南破坏性地震灾害特点。云南地区破坏性地震的人员伤亡和地面破坏主要集中发生在滇中、滇西北和滇西南地区。根据统计分析，云南地区破坏性地震的平均人员伤亡人数（Ｎ）与地震震级（Ｍ）的关系为：ｌｇＮ＝１．５Ｍ－７．４。人员伤亡数（Ｎ）与震中距Ｄ（ｋｍ）的关系为：ｌｇＮ＝０．８－０．０２７Ｄ（６．０—６．９级地震）和ｌｇＮ＝３．２－０．０５Ｄ（７级以上地震）。出现地面破坏现象的最大震中距离（Ｄｍａｘ）和震级的关系为：Ｄｍａｘ（ｋｍ）＝５２Ｍ－２９８（地表裂缝）；Ｄｍａｘ（ｋｍ）＝１８Ｍ－９３（崩塌滑坡）；Ｄｍａｘ（ｋｍ）＝５０Ｍ－２８１（滚石）。
Yunnan is an earthquake prone area. A total of 613 destructive earthquakes occurred in Yunnan from 1652 to 1994, including 553 earthquakes with 5.0-5.9 earthquakes, 49 earthquakes with magnitude 6.0-6.9 and 12 earthquakes with magnitude 7.0-7.9 Times, 8 earthquakes 1 time. In addition to the direct human casualties and the destruction of structures, the devastating earthquakes in Yunnan also caused surface damage including rockfall, collapse, landslide, debris flow, ground subsidence and sand blasting in the earthquake zone. These ground damage caused Casualties, destruction of buildings and farmland, forming the devastating earthquake disaster in Yunnan. The casualties and ground damage caused by the devastating earthquake in Yunnan mainly occurred in central Yunnan, northwestern Yunnan and southern Yunnan. According to statistical analysis, the relationship between the average number of casualties (N) and the earthquake magnitude (M) of a devastating earthquake in Yunnan Province is: lgN = 1.5M-7.4. The number of casualties (N) and epicentral distance D (km) are as follows: lgN = 0.8-0.027D (6.0-6.9 earthquake) and lgN = 3.2-0.05D (level 7 Above earthquakes). The relationship between the maximum epicentral distance (Dmax) and the magnitude of the surface damage is: Dmax (km) = 52M-298 (surface cracks) Dmax (km) = 18M-93 (landslide) Dmax (km) = 50M- 281 (Rolling Stone).
