GeoSocial: exploring the usefulness of social media mining in the applied natural geohazard sciences

Obtaining real-time information about a geohazard event as it unfolds, such as a flood or earthquake, used to be largely limited to the professional media. Nowadays, obtaining news stories from social media (e.g. Facebook, Twitter, YouTube, Flickr etc.), directly as they unfold, is becoming the ‘norm’ for many in society. The Haitian Earthquake in January 2010 and the Great East Japan Earthquake in March 2011, provided some of the first natural hazard examples, to really demonstrate the power of social media over traditional news sources for obtaining, live information from which people and authorities could gain situational awareness.
