Just for fun, and because I just spent a week in Iceland on vacation (awesome place!) I pulled some quake data from the Iceland Meterologic site and displayed the recent quake swarm under the Barðarbunga volcano in ArcScene as a time series. At the time (about 5pm Iceland time on 19-Aug-2014) there were 1,600 quakes in the last three days. In this series it appears to me that they are starting to focus in a vertical column which could indicate magma movements towards the surface. I have attached the ArcScene (v10.0) project with a file GDB of the data, and a georeference image of the surface. Could be interesting soon.
Note: the data is available here: http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/#view=map
And there is a pretty cool visualization on the web here: http://baering.github.io/ (NOTE: This does not seem to work in IE, but does in Chrome) Way easier that ArcScene...
