For some time I was thinking to implement a heatmap layer for Google Maps, but could not have a chance to do so. Coming across Patrick Wied's code for the same purpose, I tried to play with his code a bit. Remembering the old earthquake map, I used Patrick's code to create a earthquake density map for Turkey using the Kandilli's data.
Above is a snapshot for the produced map. Colors changing blue to red implies increasing earthquake magnitude or more earthquakes around that area. Click the image to see the active version of the map.
