Sounds generated by seismic activity
Geographic information of an event is used to procedurally generate sounds. They also determine the position of the visuals on the screen.
The visuals and sounds are controlled by a number of data points related to each earthquake event. The depth changes the pitch of the note while the magnitude influences the radius of the circle.

Mapping events to sound
Earthquake events are converted to music notes based on their depth, and some randomness is introduced to avoid situations where the same note is played multiple times. The melodic motion is also constrained to short distances to keep the sound pleasing.
