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,April 24,the earthquake caused a total of 196 people dead,21 missing and 11470 injured.With the development of information and communication technologies,microblog shows great potential in promoting emergency response as it provides an easily accessible platform on which disaster information could be assembled and rapidly disseminated to a large number of audiences.In view of this,we built the dataset of Ya’an Earthquake based on Sina-Weibo microblogs posted within Sichuan Province during 7 days after its occurrence.Sina-Weibo,a platform for information sharing and exchange,entertainment,leisure and life services,was launched in August 2009.It provides a platform where the public can communicate,express their feelings,offer suggestions,and so on–a platform that is essential for earthquake data search,query and publishing.
