On March 11, 2011, an earthquake registering 9.0 on the Richter scale struck the coast of northeastern Japan, triggering a tsunami that would kill more than 18,000 people and leave an estimated $180 billion in damage. The news media worldwide provided extensive coverage of the disaster and its aftermath, but millions of people also turned to the web to learn about the event on the video sharing website YouTube.

A new report from the Pew Research Center’s Project for Excellence in Journalism¬†examined 15 months’ worth of the most popular news videos on the site (January 2011 to March 2012)—some 260 different videos in all-by identifying and tracking the five most-viewed videos each week located in the “news & politics" channel of YouTube, analyzing the nature of the video, the topics that were viewed most often, who produced them and who posted them.

Above is the most-watched news video that was shot by what appeared to be a fixed closed-circuit surveillance camera at the Sendai airport. Read our full report here:  http://pewrsr.ch/ODl8U9
