Washington: A team of scientists from the National Information Communications Technology Australia (NICTA) and the University of California in San Diego, have revealed that tweets from disaster affected regions, can help determine the damage caused by a natural disaster in just a few hours,

 The researchers analyzed Twitter activity before, during and after Hurricane Sandy which caused severe damage in the US four years back.

Hurricane Sandy caused more damage than any other storm in US history, with an economic impact in the region of $50,000 million.

Hundreds of millions of geo-located tweets making reference to this topic were collected from 50 metropolitan areas in the US.

“Given that citizens were turning to these platforms for communication and information related to the disaster, we established a strong correlation between the route of the hurricane and activity on social networks,” said Esteban Moro Egido from Universidad Carlos III de Madrid.

The study, published in the journal Science Advances, found that Twitter is useful for the management, real-time monitoring and even prediction of the economic impact that disasters like Hurricane Sandy can have.

The main findings were obtained when the data relating to Twitter activity was examined alongside data relating to both the levels of aid granted by the Federal Emergency Management Agency (FEMA) and insurance claims.

The team found that there is a correlation between the mean per capita of social network activity and economic damage per capita caused by these disasters in the areas where such activity occurs.

Furthermore, researchers verified the results obtained from Hurricane Sandy and were able to demonstrate that the same dynamic also occurs in the case of floods, storms and tornadoes.

“In this way, communication on Twitter allows the economic impact of a natural disaster in the affected areas to be monitored in real time, making it possible to provide information in addition to that currently used to assess damage resulting from these disasters,” the authors pointed out.

Moreover, the distribution space of the event-related messages can also help the authorities in the monitoring and evaluation of emergencies, in order to improve responses to natural disasters.

The authors suggest that we are facing an increase in the frequency and intensity of natural disasters as a consequence of climate change.

“We believe that this is going to cause even more natural disasters and, therefore, the use of social networks will allow us to obtain useful supplementary information,” professor Esteban Moro pointed out.

“We are trying to see if there is a relationship between activity on social networks and climate change which will affect us in the future,” he added.

Lockdowns in China Force Urban Communities to Defy Censorship and Vent Frustration Online

Shanghai’s rich middle class is leading a wave of online dissent over the strict and prolonged lockdowns imposed in various parts of the country. Chinese internet censorship is struggling as patience is wearing thin in many urban centers, coming up with creative forms of online protests.

Social Media Posts Revealing Lockdown Tension in Shanghai

Drawn-out lockdowns are nothing new in China as authorities insist with the nation’s zero-Covid policy since the start of the pandemic. Currently over This time around, however, metropolitan areas like Shanghai are increasingly difficult to keep quiet, given that its more than 25 million residents have seen weeks of total isolation along with food shortages and many other service interruptions.

Dozens of towns and reportedly over 300 million Chinese citizens have been affected by lockdowns of different severity. As expected, urban netizens have been most outspoken over their difficulties by finding creative ways to get around state censorship and bans placed on topics, news comments and spontaneous campaigns.

Shanghai residents have been using mobile proxies and hijacking seemingly unrelated hashtags to talk about healthcare issues, delivery failures and the overall severity of their situation. The “positive energy” that the Chinese government wants to transmit during the recent prolonged series of lockdowns does not come naturally to those counting food supplies and online censors are working hard to filter words, trending topics and undesired social media sharing.

WeChat groups and message threads are under constant monitoring. Posts questioning the zero-Covid approach have been quickly deleted, including by leading Chinese health experts like Dr. Zhong Nanshan. Video footage is soon censored and protests and investigations are quickly made to disappear.

Where this has not worked, officials have exposed banners with warnings and outright threats like “watch your own mouth or face punishment”, while drones have been patrolling the city skies. Yet, if anything, this has led to further tensions and unspoken confrontation with Shanghai’s educated and affluent middle class.

Creative Online Solutions Harnessing Civic Energy

Announcements by Chinese social media that they would be publishing the IP addresses of users who “spread rumors” have not helped either. Tech industry research has shown that much of Asia’s tech-savvy population has a habit of using mobile proxies and other privacy tools, quickly finding workarounds to browse the internet freely and talk to the world about the hottest topics.

The sheer volume of forbidden posts is already a challenge for the very censorship system, experts explain. Unable to track all trending hashtags, state workers overlook topics that speak about the US, Ukraine or other popular news. Linking human rights elsewhere to their situation, Chinese online dissidents establish their informal channels and “hijack” the conversation to share personal or publicly relevant information about the Covid suppression in their town.

Sarcastic and satirical posts still dominate. Others hope to evade the censors by replacing words from famous poems or the national anthem. One thing is certain – social media, when harnessed with the right creativity, has proven its ability to mount pressure on the government in even some of the most strictly controlled tech environments like China.
