| 摘要 | The Ya’an Earthquake occurred on April 20, 2013 (Beijing time). Its epicenter was located in Lushan County, Ya'an City, Sichuan Province, and the magnitude of this earthquake was 7.0. As of 14:30, 24th April, the earthquake caused a total of 196 people dead, 21 missing and 11470 injured. With the development of information and communication technology， we find that micro-blog system had shown great potential in promoting emergency response because they provided an easily accessible platform on which disaster information could be rapidly organized and disseminated to a large number of people. In view of this, we built this dataset of Ya’an Earthquake based on the Sina-Weibo microblog posted within Sichuan Province during 7 days after the earthquake. Sina-Weibo, a platform for information sharing and exchange, entertainment, leisure and life services, was launched in August 2009. Sina-Weibo can be used to search, inquire and publish post-earthquake-related data. It provides a platform where the public can communicate, express their feelings, offer suggestions, and so on. |
