Dot Distribution/Isopleth Map

 

The following map shows the distribution of earthquake and tremors in relation to social media posts.  This map includes the earthquakes and their subsequent tremors along with a "shake index" provided by the USGS.  The epicenter of the earthquake can be seen in the upper right hand corner of the image; indicated by the large pink circle.  The map also includes Youtube uploads, tweets, and flickr posts as well.  Through this we can see that there is a clear relationship between density of earthquake aftershocks and social media posts.  This gives a clear indication that social media has become ingrained into our everyday lives.  Granted this tragedy is more involved than updating what you did for the day or what kind of mood that you are in, but these posts have proven (through more than one situation) to be a resounding force  in news propagation.
