Popis:	SUMMARY As a steady new network communications tool, social media have reached global proportions. This phenomenon has had an impact on societies all over the world. Above all, people provide information to Twitter and Facebook on a daily basis. As a result, vast amounts of data exist on Twitter and Facebook, and we can expect to gather useful information from these services. Twitter was changed by the 2011 Tohoku Earthquake. Further, Twitter greatly contributed to the diffusion of information. For example, many users checked on the safety of their friends or family. However, numerous false rumors were spread, probably due to the source of information being unclear. To prepare for future disasters, we must analyze the diffusion of information through social media as soon as possible. In this paper we analyze how the diffusion of information on Twitter has been influenced by structural changes in the network that are caused by communication among users. As a result, just after the 2011 earthquake in the Tohoku region in Japan, it became easier for information to spread in the network. However, this means that misinformation too can spread. We also found that a few users believed misinformation despite being corrected.
