Seoul Station (서울역) Before the Chusok Holiday

Here's a quick look at tweets that mention Seoul Station on the day before the 2014 Chusok holiday.  Lots of people are traveling, but there are also political protests going on around the plight of the families of the Sewol ship sinking.  The massive blue cluster represents tweets from those activists and politicians who wanted to remind people about the cause before they traveled to their hometowns for the holiday.

A quick social graph on NodeXL using 'plaza' as a search term.  For the most part, these tweets focus on continued protests from activists organizing around the Sewol disaster.
