Twitter and the Christchurch Earthquake Towards better strategies for social media in disasters: February 2011 earthquake building on lessons learnt in September 2010 #eqnz and key Twitter accounts already established Several key accounts sharing the load and dividing responsibilities More experienced use of Twitter by residents and authorities Clear shift in attention after the immediate rescue phase: Marked differences in list of most @replied/retweeted accounts Some tracking of current problems / issues / fears may be possible Decline in overall tweet volume / diversification of #hashtags?

Background: Researching Twitter #hashtag studies: Selected #hashtags captured from the Twitter API using yourTwapperkeeper Data processing using custom-made tools – keyword and network analysis Statistic and network visualisations – including dynamic visualisations Broader research: #hashtags are limited – much additional activity outside #hashtags How do #hashtags emerge, how do users encounter and choose them? How much does Twitter use during crises differ from everyday usage? Mapping Online Publics: ARC Discovery project, 2010-12: Assoc.

The document discusses energy generation and usage in the United States. It states that in 2014, the US generated about 4,093 billion kilowatt hours of electricity, with fossil fuels (coal, natural gas, and petroleum) accounting for about 67% of generation. Coal specifically accounted for 39% of electricity generation while natural gas was 27% and nuclear was 19%. The document then discusses various strategies and their potential contributions to meeting the projected increase in global energy demand to 30 terawatts by 2050.

Hunting for (energy) demanding practices using big & medium sized data

Ben Anderson

Dr. Ben Anderson presents on hunting for energy demanding practices using big and medium sized data. He discusses linking transactional energy use data to surveys and time use studies to identify household practices that influence demand, such as cooking and cleaning routines. New sources of data like smart meter traces are also explored for revealing rhythms of demand. Challenges include scaling up micro-level insights and taking post-disciplinary approaches to analyze data of different sizes.

This document discusses the use of social media, particularly Twitter, during crises and natural disasters. It analyzes the hashtags #qldfloods and #eqnz which were used during the 2011 Queensland floods in Australia and the 2011 Christchurch earthquake in New Zealand. The analysis shows how Twitter was used to coordinate information sharing during the crises and how official accounts helped establish hashtags and amplify key messages. It also compares Twitter usage and themes between the different events.

Tracking Crises on Twitter: Analysing #qldfloods and #eqnz

Axel Bruns

This document summarizes research on the use of Twitter during crises and natural disasters. It analyzes the #qldfloods and #eqnz hashtags around the 2011 Queensland floods in Australia and the 2011 Christchurch earthquake in New Zealand. The research found that Twitter provided a way to coordinate information through central hashtags. Official emergency accounts helped establish hashtags and cut through large amounts of public posts. The types of tweets shifted over time from rescue information to recovery updates. Lessons from previous crises helped authorities and the public make better use of Twitter during subsequent disasters.

Social Media Use in the Queensland Floods and Christchurch Earthquake

Axel Bruns

This document discusses social media use during emergencies like floods and earthquakes based on case studies of hashtags like #qldfloods and #eqnz. It finds that Twitter is increasingly used to coordinate information sharing during disasters, with authorities, media, and individuals all actively participating. However, Twitter activity declines after the immediate emergency response phase, and its role must be considered as part of the wider media ecology. The document also outlines research analyzing the structure of social networks on Twitter to map how public discussions form and evolve on the platform.

Social Media Use in the Queensland Floods

Axel Bruns

This document summarizes research on the use of social media during the 2011 Queensland floods in Australia. It analyzes tweets using the hashtag #qldfloods to understand themes over time, key actors and networks. It finds that #qldfloods served as a coordinating tool, and that the Queensland Police Twitter account @QPSmedia emerged as a central information source. It also compares social media use across different recent crises and outlines next steps for the research.

Social Media and Crisis Communication

Axel Bruns

This document discusses the use of social media, particularly Twitter, during crises and emergencies. It provides examples from the 2011 Queensland floods in Australia and the 2010-2011 earthquakes in Christchurch, New Zealand. Key findings include that Twitter allows for rapid sharing of first-hand information; different platforms are suited to different communication needs; and social media can help with community self-organization and resilience during crises. The document advocates analyzing social media communication patterns to improve emergency response strategies.

Local and Global Responses to Disaster: #eqnz and the Christchurch Earthquake

Axel Bruns

This document discusses local and global responses to disasters using the 2010-2011 Christchurch earthquakes in New Zealand as a case study. It analyzes data captured from Twitter using the hashtag #eqnz to understand communication patterns and how social media were used. The analysis revealed shifting attention and roles of key Twitter accounts over time, from immediate rescue to longer-term recovery. It advocates for better social media crisis communication strategies and tools to inform, support, and organize affected communities.

Analysing Twitter Activity in Crisis Contexts

Axel Bruns

This document analyzes Twitter activity during crisis contexts like floods and earthquakes. It finds that Twitter provided first-hand information and photos during crises. Communities formed around hashtags like #QLDFloods and #EQNZ to share updates and organize relief efforts. Analysis of these hashtags revealed changing patterns in retweets and mentions of emergency services and media over time, from rescue to recovery phases. The document advocates for better social media crisis communication strategies and tools to monitor issues and improve response.

The document discusses what causes earthquakes and how the ground shakes during an earthquake. It explains that earthquakes are caused by the sudden release of elastic strain energy along faults due to the movement of tectonic plates. When the rocks reach their strength limit, slip occurs along the fault, causing seismic waves that travel through the earth. These waves include P-waves, S-waves, Love waves and Rayleigh waves, each causing different types of ground motion. S-waves and surface waves cause the most damage due to their ability to cause side-to-side shaking of the ground and structures.

Identifying the Symptoms of Destructive Polarisation

Axel Bruns

This document discusses research into destructive political polarization. It presents a project studying polarization across multiple countries over time using various online data sources. Five symptoms of destructive polarization are identified: breakdown of communication, discrediting information, erasure of complexities, disproportionate attention to extremes, and exclusion through emotions. A referendum in Australia on an Indigenous Voice is used as a case study, and analysis of social media content around it reveals examples of several symptoms, including extreme views receiving attention and complex issues being oversimplified. Further research perspectives are discussed, such as more systematically diagnosing symptoms and evaluating polarization across different forms and platforms.

Axel Bruns

The document discusses the rise and fall of Twitter as a social media platform. It describes how Twitter started as a niche platform that gained widespread popularity for connecting communities and sharing news in real-time using hashtags. However, over time Twitter struggled with inconsistent management, a slow response to misinformation and harassment, and changes that disrupted the third-party development community. After Elon Musk's acquisition, he laid off much of Twitter's staff and promoted policies that led to increased confusion, chaos and the spread of disinformation, contributing to Twitter's decline.

Axel Bruns

This document summarizes the rise and fall of the Twitter platform. It describes how Twitter started as a niche site in 2006 but grew to be an important platform for news, communities, and public discourse. However, inconsistent management and slow responses to challenges like misinformation contributed to its decline. Elon Musk's chaotic leadership after acquiring Twitter in 2022 accelerated this, through mass layoffs, attacks on content moderation, and promotion of disinformation, further undermining the role Twitter once played.

Axel Bruns

This document discusses types of polarization that can be studied in digital media, including micro, meso, and macro levels as well as issue-based, ideological, affective, perceived, and interactional forms. It describes a research project studying drivers of partisanship and polarization across multiple countries over time using digital methods like topic modeling, sentiment analysis, and network analysis. Examples are given of analyzing polarization on topics like climate change on Twitter and political rhetoric on Facebook. Finally, it outlines perspectives on further defining symptoms of dysfunctional polarization and developing more systematic diagnostic approaches.

Gatewatching 5: Weaponising Newssharing: ‘Fake News’ and Other Malinformation

Axel Bruns

This document summarizes a research project analyzing the dissemination of problematic information on Facebook from 2016 to 2021. The researchers compiled a list of over 2,300 "fake news" domains and collected Facebook posts sharing links to those domains. They analyzed the link-sharing network between public Facebook pages/groups and domains, identifying clusters that commonly share the same domains. They also analyzed the on-sharing network between public Facebook spaces to identify communities with common interests spreading this information. The goal is to better understand the dynamics, themes, and networks involved in spreading problematic information at scale on social media over time.
