On February 27, 2010 a powerful earthquake followed by a tsunami stroke Chile. The study of mortality during this emergency can provide important public health information.
To describe the main characteristics of people who died during the earthquake and the following three months.
Cross sectional analysis of death records databases obtained from Department of Health Statistics and Information of the Ministry of Health and the Coroner office.
Until May 25,2010, 505 corpses were completely identified. Seventy two of these corresponded to people aged 80 years or more. The higher age adjusted death rates per 100,000 inhabitants were observed among subjects aged more than 80 years and those aged 70 to 79 years (22.6 and 7.7 respectively). The higher rates of deaths were observed in regions where the earthquake had a higher intensity and coastal regions affected by the tsunami. The causes of death were trauma in 75% of cases and drowning in 25%. There was no association between the Mercalli scale of earthquake intensity and rates of death. Among deceased subjects, there was a concentration of unemployed, under educated and low socioeconomic status subjects.
After the earthquake, the higher rates of deaths occurred among older people and in the region of the epicenter of the earthquake. Most deaths were due to trauma.

描述在地震及随后三个月内死亡人员的主要特征。
对从卫生部卫生统计与信息司及验尸官办公室获取的死亡记录数据库进行横断面分析。
截至2010年5月25日，已完全确认505具尸体身份。其中72人年龄在80岁及以上。在80岁以上人群和70至79岁人群中，观察到每10万居民年龄调整死亡率较高（分别为22.6和7.7）。在地震强度较高的地区和受海啸影响的沿海地区，死亡率较高。75%的死亡原因是创伤，25%是溺水。地震强度的麦加利震级与死亡率之间没有关联。在已故受试者中，失业、受教育程度低和社会经济地位低的人群较为集中。
地震后，老年人和地震震中地区的死亡率较高。大多数死亡是由创伤所致。
