Mike Dickison, from the excellent Pictures of Numbers information design blog, has been working with GeoNet’s seismic data. This morning Mike asked the Internet “has anyone produced a graph of all the aftershocks and their intensity over the past two days?” It seemed that nobody had, so he created his own … by hand.

The figure below is a scanned copy of Mike’s bar graph of aftershocks following the large quake. Note the tall line at the far left of the chart. That is not the Y axis – that’s the big one.

A chart created with actual graph paper is a rare and wonderful thing. This made my day.
