See this map of seismic activity in India. The map is divided into different bands. Red are the most active regions and white are the most stable regions. You will need to use the color filters of the vOICe to hear the different bands.
Yellow regions are the areas with a moderate amount of seismic activity. The color identifier of the vOICe is able to identify some of the colors in the image. I wish it would give me a complete color breakdown. It does render the entire image after all.
