EU projects – Social media is a serious and fast growing phenomenon for creating and maintaining social links. The convergence of social networking and mobile media technology is also shifting the way people communicate, and gain or share information, especially during emergency or crisis situations. For example, during catastrophes throughout the world, like the Loveparade disaster 2010 in Germany or hurricane Sandy 2012, social media has been widely used. The EmerGent project, which will run for 3 years, will examine the positive and negative impact use of social media in emergency situations involving citizens, emergency service organisations and public authorities. EmerGent will provide guidelines and tools on how to use social media which the emergency service organisations could use during and after emergencies in the future.
