This is the first outcome of my exploration of scientific data and methods by means of art and design. I’m generating the logo using the realtime seismic data of a nearby station and the recent earthquakes.
The basic shape is an circle. This combines basic elements of seismogram visualizations: the line and the drum of a helicorder.
Along the circle nodes are distributed. Each node acts as a damped spring-mass system. The position of the nodes is altered by radial forces correlating with the frequency content of a seismogram and the temporal distribution of the amplitude maxima of the seismogram. The color of the resulting shapes is determined by the maximum magnitude of the worldwide earthquakes which happended during the timespan of the processed seismogram. For the color mapping I’m using a rainbow colormap:
Currently a new logo is computed every hour using the data of the station ARSA of the Austrian seismological network. The computation is triggered 20 minutes after each full hour to account for delays in the reporting of earthquakes. The updated most recent logo ist displayed in the navigation bar on top of this site. To check the most recent earthquakes visit www.seismicportal.eu/.
Here a the last 10 computed logos:
