Obtaining real-time information about a hazard event as it unfolds, such as a flood or earthquake, was until relatively recently largely limited to the professional media. However, social media (e.g. Facebook, Twitter, YouTube, Flickr ,etc.) have been increasingly used in recent years to gain situational awareness. More and more people are looking to social media as additional, more immediate sources of information.
What is GeoSocial?
This site is temporarily out of action whilst it undergoes further development.
GeoSocial (v2.0) is a tool that allows users, including BGS scientists, to display geoscience-related posts from social media sites such as Twitter. Social media provides a different channel for gathering potentially useful information for scientific analysis from the public. The aim of GeoSocial is to explore whether we can make use of the wealth of information that is publicly available through such sites to help advance scientific understanding and provide better and more timely advice.
How does GeoSocial work?
GeoSocial identifies potentially relevant postings about different geoscience themes (e.g. landslides, aurorae, flooding, volcanic eruptions and earthquakes) from Twitter and, if they can be located, displays them on a map interface. The application currently relies on keyword filtering and currently only searches for English terms. As such, some relevant postings may not be retrieved where they do not meet the predefined search criteria.
Although a level of filtering has been conducted, the posts that are displayed are content provided by Twitter and outside of the BGS’s control. The BGS therefore cannot guarantee that these postings won’t contain obscenities or cause offence. Over time, we hope to be able to build on the methods behind this data filtering to improve the relevance of the content that is displayed.
We hope to develop this tool further to improve the usefulness of the information it returns. This may be through:
- novel data analytical techniques (e.g. using tools such as TensorFlow)
- exploration of other web tools that allow user-generated content to be collected
- crowd verification
In time, we also hope to provide analysis of the usefulness of this type of information to (BGS and other) hazard scientists when it is compared to structured data holdings, field observations and models. We will also explore opportunities to transfer the knowledge gained to other science themes.
Use of your information and BGS disclaimer
This site supports Twitter services that are aimed at helping and supporting users to share information with the world. Tweets are then displayed on the map using positional information contained in the tweet, either as coordinates or text. The BGS will endeavour to locate the social media post (e.g. a tweet) as accurately as possible on the map using this positional information. Since the positional accuracy cannot be guaranteed, the BGS has limited the zoom scale of the application.
Where, through any error, act outside our control or misjudgement, the BGS is found to hold any of your personal information, we promise to handle it in line with our policy, which will include:
- making sure you know why we need it
- protecting it and making sure nobody has access to it who shouldn’t
- letting you know if we share it with other organisations in order to give you better public services, unless you say no to such an action
- making sure we don’t keep it longer than is necessary
- removing it from the site if it is identified and you no longer wish it to remain on the site
Please inform us via the BGS Enquiries team of any content you wish to have removed from this site and we will promise to act to review and remove that content as required.

We are using citizen science for people to develop a shared understanding of hazardous phenomena and for communities to contribute to hazard forecasting and early warning.
